Are they integral with the system board or separate components?I ordered an X61 tablet on 9 Nov and received it on the 27th. The backlight kept crapping out so it went back to Easyserv on 4 Dec. I got it back on the 20th and the info sheet said they'd replaced the system board and restored the HD to as-shipped state.Yesterday the backlight started going off again, and today it wouldn't come on at all. Obviously it's got to go back again, but I'm curious if replacing the system board was the right thing to do.

I have an IBM Thinkpad and recently my backlight has been failing (you can still barely make out then screen but its all dark) and sometimes it comes on when i start the computer but this is getting rarer and rarer.

I can fix this but my problem is determening if the problem is the backlight or the inverter as i dont want to buy the wrong part. Is there a way to detect which is the problem or should i just buy both? which is it more commonly?

So my laptop (same one I've been trying to get a mouse to work on) had a blank screen, at all times. I can vaguely see the desktop or whatever is shown by using a flashlight, but I'm confused whether this requires a new backlight, or simply a new inverter.

I've already found the thread concerning opening up around the screen to view the FRU and PIN numbers for my current inverter (FRU: 27K9951 EC, PIN: 27K9952, on an IBM ThinkPad R51), but I'm unsure where to go form here. After a few Goole searches I've found a few decent prices (best being around $50) for an inverter, but I want to be sure I'm buying the right part to fix my problem. Just some confirmation or helpful tips would be helpful from the community, thanks a bunch.

P.S. I have already found the thread with the pictures of removing the frame, and from it I've understood that it is the inverter I need to replace, but better safe than sorry, I suppose - don't want to buy a $50+ part I don't need.
 

A:Inverter vs. New Backlight Bulb?

Inverter.
That is a very high price for an inverter for an R51, but the R51 is a very rare computer... so you may have to pay it.
you need a very good quality #1 hard steel philips screw driver, great care in removing and replacing the screw covers, and the time it takes to remove and replace 18 screws. But the inverter just plugs in. Mark all your screws as you remove them as they are not all the same length or diameter. But the most important function is removing the screw hole covers so you can use them again. You will benefit from a very, very thin flat blade screw driver or other tool to lift the screw covers out and off. You will need a nice adhesive that remains soft when you replace them.
It is very rare for an inverter to go out in that model.

My Inspiron 1545 laptop screen no longer works properly. The display is extremely dim (just about impossible to see) so I figured I'd replace the backlight.

I am having problems diagnosing the error with a notebook LCD display inverter.Symptoms: After switching the notebook on, the LCD backlight comes on but the intensity oscillates rapidly (flickers). After about 1 second the backlight turns off completely. Once the backlight has turned off, the AC output of the inverter measured with a DVM is 0 Vac.I visually checked the inverter board and there are no obvious faults.Given the symptoms, can anybody venture a guess at the problem?On the one hand I am tempted to say that the backlight is ok (after all it ignites) and the problem is more likely to lie with the inverter.On the other hand I am wondering whether the flickering of the bulb (faulty bulb?) causes a open-circuit protection of the inverter to kick in after 1 second.So in summary I am not quite sure whether the fault is more likely to lie with the bulb or the inverter.

What I'm wondering is, this sounds like instructions for replacing just the inverter, but what if my problem is with my backlight as well (or instead)? Apparently they can also be replaced, but I've read suggestions that this may involve soldering. If you are lurking, raybay, do you know specifically what is required to replace the backlight on this model?
 

A:Replacing backlight/inverter on thinkpad r51

You can get the inverter, new, on eBay for $9.95 on up to $20... DO NOT BUY A USED ONE, and DO NOT BUY ONE FOR A SLIGHTLY DIFFERENT MODEL. It is the screen that determines the model number... and that inverter/backlight is part of that particular model number.
Your inverter and your backlight are basically the same thing the failure of one affects the other... or they are in the same device depending on the laptop.
None of the IBM Lenovo units need soldering... but you have to remove about 20 screws, and remove the rubberized screw covers... so making it pretty again when you are done is the hard part... as you have to learn how to reapply the screw covers and the rubberized stickum.
USE VERY GOOD, VERY TOUGH TOOLS. DO NOT USE TOOLS that wear easily. Cheap toosl will mar the screws and ruin stuff.
First you buy the backlight.
Second, remove the keyboard.
Third, you remove the screw covers with a very thin device like a 1/2 or #1 flat screw driver, only with thinner metal... and some tweezers to lift off and store the screw covers which are mostly very thin, round flat rubber disks.
You need some soft of bowl or series of cups where you can put the different size screws. You need to keep a chart of which size screws come from where... Unless you have a good mind for those sorts of things and nobody does.
You may find it easier to remove the back of the computer where the screen is kept... and CAREFULLY remove the ribbon cable for the screen that plugs in beneath the keybo... Read more

Are there any Toshiba people out there who would know if ALL the M30X series Satellites used the same or virtually the same backlight inverter?

My model number is simply M30x with no dash and additional characters (looked on bottom and on box) and all the compatibility info I can find is for M30X-Sxxxxx or M30X-x0. I'd feel more comfortable ordering the part, knowing the affirmative. MoniServ claims to have a hardier new inverter that I 'm planning to try.

My screen went dark after 2 and a half years use. I can still see an extremely faint shadow of the desktop; so I know the problem isn't something more drastic. I suppose it might also be the backlight itself - if so can someone help in finding the right part to replace that? Is that something a gutsy non-professional can do? I can send more info if needed - just tell me what.

Thank you SO much,

Hi,
Over the past year, since I upgraded the memory on my IBM R31 Thinkpad, I have had intermittent problems with my screen blacking out. It's not completely gone, just extremely dim, but I can make out the things on screen by using a torch. At first, I was able to trigger it back by leaving the lid open and never closing it, taking all the usbs and plugs out of the back, or re-starting it.

However, it seems like nothing I do will trigger it on now. I've done a search and apparently the commonest cause is that the inverter needs replacing. Would this seem like a sensible thing to buy?

http://cgi.ebay.co.uk/IBM-Thinkpad-...goryZ162QQrdZ1QQssPageNameZWD1VQQcmdZViewItem

The only thing I'm thinking now is, i've had this laptop for 5 years now!! I'm not sure if it's worth fixing or upgrading anymore. I mean, I love it, just cos it's lasted this long, i've upgraded the memory from 128mb to 384mb and i've bought a wireless card for it but would it be worth trying to buy and fix myself a new inverter or just buy a new laptop?

Thanks!!
 

A:IBM Thinkpad - Backlight screen black.. inverter replacement?

Well the most common things would be the inverter board you linked to, or the backlight bulb itself.

If the laptop still suits your needs, in terms of performance than its much cheaper to just fix this one, than buy another laptop of similar quality.

The great think about IBM is the great support. Here is a link to the hardware manual for the R30 model.
http://www-307.ibm.com/pc/support/site.wss/MIGR-39797.html
It should tell you how to get at the inverter and bulb.

Even if you do get a new laptop, its still worth it to fix this one up as a backup laptop. 20-30 pounds and a couple hours to fix it isn't that bad.

And i believe its called a flashlight not a torch. You could burn the house down with a torch

Sooooo.... I'm working on a free hand-me-down laptop. Had a hard drive problem, which I fixed and happened to find 4GB of RAM to toss into it... and what do ya know, the screen starts messing up as soon as I fixed it...

The laptop is not very old so I would like to fix it... onto my problem.

The screen sort of "flickers" and "moves around" and also has a pink tint to it every once in awhile. The screen is this way as soon as I power on the laptop, and having it plugged into the wall proves no difference. Another strange thing is, if I leave it on, after about 5-10 minutes its works perfect, but only for about 15 seconds, then back to like the picture above.

- Tried hooking it up to my desktop monitor, works great.
- Took this thing apart, checked the all of the wire connections, seem to be solid and fooling with them with the lappy on did no justice. I'm stumped basically.

So now I'm wondering, backlight or inverter?

A:Acer Laptop Screen Problem-Inverter or Backlight

Normally when the backlight goes out, it will affect the full screen. It can flicker or go out completely. This can be checked with a flashlight held up to a text area on screen and looking for the contrasting image on the LCD. From the way you describe the working then stopping, it sounds to me like the inverter is building up a charge then letting go.

I had a customer dropp off an Inspiron 1525 laptop due to the "not charging issue". Therefore, the dc jack power board was replaced. However, when the laptop was put back together and turned on, we noticed that the LCD was extremely dark as though the backlight was shot.
When we hooked up the 1525 to an external monitor, it worked great. We thought it was the inverter so we replaced it and still "no backlight"! We changed the lcd cable and still "no backlight". I even swapped out the LCD screen and still "no backlight". I tried the original LCD screen on an inspiron E1505 and it worked great. What the heck is going on? I even tried connecting the LCD screen to another 1525 motherboard that we had around collecting dust and still no backlight. I'm extremely upset at this point. This problem seems to defy all logic to me. Obviously the LCD Screen and inverter are fully working.. Any thoughts? Is there somekind of weird issue that only dell knows how to fix. I'm thinking of getting another 1525 motherboard but fearful it will not fix the problem. What am I missing?

I have a Toshiba Laptop... A week ago, my screen has started going black and coming back. Just two days ago, my screen went black and did not come back. I thought my screen was dead but then I figured that the back light of my screen was gone because when I look at the screen carefully, I barely see the things on my desktop....When I turn on my laptop, I can see my screen for 3-4 seconds, then it goes black again. Same thing happens when I log on after log off... It again gives me the light about 3-4 seconds after just logging on, then it goes black again. I finally opened up the screen, and found the display inverter... and it again gives me the light 3-4 seconds after I plugged out and plugged in the inverter cable. I am not sure whether the problem is the inverter itself of the inverter cable. I really need help.
 

A:Distinguishing between display inverter and inverter cable problem.

It sounds like the inverter may be sensing an overload on its output(s) and shutting down after a few seconds. Some possible conditions causing it could be 1) the backlight lamp(s) failing, 2) arching of the inverter output cable to itself or the frame of the LCD panel, or 3) a failure of the inverter's overload sensing circuit that makes it think it is being overloaded, when it really isn't.

WARNING: Use extreme caution when working around a CCFL inverter with power applied to it. Portions of it will have hundreds of volts of electrical energy on it. You could receive a nasty (and possibly fatal) shock if you come in contact with the high voltage.

My sister dropped her T410 and cracked the LCD screen, which clearly was not covered under the basic warranty.  The $950 quote for repair was a little steep (basically the cost of the laptop) so we decided to try a repair ourselves.  I replaced the LCD screen with a model suggested by the Lenovo rep.  With the new screen in place, the backlight doesn't function at all (can see information on the screen with a flashlight but otherwise nothing).  I also put the old screen back in (which previously was backlit despite being cracked) and observed the same problem.  I made sure the LCD cable was seated firmly at both ends. Considering things as they stand now, my question is about the best route to take from here.  As I understand it, since the LED backlight is powered by the system board, we either buy a new system board or use this laptop as a "desktop" attached to a standalone monitor.  Replacing the LED sub card seems questionable for this particular problem (saw another post here with that conclusion).  We could replace the LCD cable, but it seems to me more likely that the fuse on the motherboard is blown.  If it comes down to motherboard vs. desktop use, we'll probably avoid the motherboard replacement since it is somewhat expensive. Am I missing any obvious ideas?  Should I consider replacing the LCD cable more seriously?  Is the LED sub card more relevant to the LCD/backlight than I think?  I'm hoping t...

New to the forum so Hello everyone.

I understand how to turn down the level of brightness through backlight control but how do I decrease the level even further? The slider in the brightness bar is all the way down (left) yet at nights the light from backlights are too bright!

Couldn't someone please help me out?

Dimming is an option but it still doesn't decrease backlight.

A:Backlight - Decreasing backlight Level more

let's see: there should be backlight and brightness adjustments on the monitor, plus contrast which does affect final light output somehow, plus all those except backlight should be duplicated inside video drivers on your computer and gamma on top of that. If it's a laptop then there should be some combination of Function key and arrows to adjust backlight directly. If you can't get the screen dark enough with all those controls, could be something wrong. If controls are too limited and your environment is totally dark then buy anti glare screen protector, that usually cuts the light coming out probably at least by half.

Recently my Inspiron 8600 started booting with a black screen. Shining a flash light on it, I could see login prompt then XP desk top.

A:LCD inverter?

To be honest, the best way is by substitution of the inverter or the backlight. Whichever fixes it is the problem.

The high voltage produced by the inverter could be measured with an appropriate meter, but as it is effectively a ballast the results could be affected by the CCT backlight, it may be hard to deduce just which is the problem. Open circuit voltage would also be inconclusive, it could still be a defective inverter that falls over with the load and fails to strike the CCT.

Here's the problem -
4 year old Gateway laptop, LCD went dark suddenly (could just make out screen in certain light.)
I figured out it was the inverter, order a new one, and installed it.
Hooray, everything worked fine. Bright clear screen.
I'll say here that the drive was wiped, so when it boots it boots to "No OS found."
Booted it up and left it alone for it to charge battery. Sat for 1/2 hour with no problem with "No OS found" bright and clear.
Re-booted to begin install of OS and it lit up, showed 'No OS found" for 60 seconds, and then goes completely black, not even faint.

So I can't tell now if this inverter went, backlight is shot, or ????
Since it starts every time bright and clear I have no idea. It just goes black 60 seconds after I turn it on.

Any help would be appreciated.

I've had my laptop for around 3 years now and just last week, the lower half of the screen flickered for a few seconds. I never thought much of it but over the last few days, the problem has become more noticeable. I have done some searching around and this isn't an uncommon problem, across all makers of laptops.

I have been advised to hook up an external monitor to see if it flickers in sync with the laptop, if it doesn't then it is most likely a failing LCD Inverter.

Does anyone know how much one of these would cost over here in the UK, or if they are all compatible?

Hey,

The exact price is depending on your notebook model and display. Different notebooks have different hardware so there is no common inverter for all displays.

An exact answer you can get from an authorized service provider in your country. The guys have access to all Toshiba databases so they can tell you the part number and how much it would cost.

But, I need to know if I need the inverter board and if I need the switch on the lcd frame. I have a Compaq fp7137 monitor and the backlight doesn't like to stay on. So do I need those two parts? Thanks.
 

A:what does an inverter board do?

The inverter basically gives the backlight power to light up if you don't need light on the backlight then you won't need it

I was given a slightly beat HP laptop when one of my customers upgraded. The video chipset still works (i.e. works fine when attaching an external display) but the screen itself is acting up. When the computer is powered up, the backlight turns on but there is just a single vertical line of colored pixels. I know all of the pixels work because if I tap the side of the screen they will display normally at any given time, but then the picture seems to get distorted or slowly burns out. So I'm thinking the inverter is junk, which is an easy enough fix... but I wanted to ask someone who has a bit more experience with this sort of thing. Any ideas?

The LCD panel itself might be bad, but you can check all cable connections before you purchase any parts. i really don't think it is the inverter

Folks,

If you have a problem with a laptop screen is there a definitive way of telling whether it is the inverter that has failed or the screen? I have seen a number of forums mention the possibility of either but no way of actually definitively telling.

I have a HP NX9105 where the display is extremely dim but is just visible in light and an inverter will cost a third of the price of a screen but I don't want to buy both if only one needs to be replaced. Have tried the Fn buttons and the screen button.

Any help greatfully appreciated.

Regards, stucuk

I have a DCL LCD19A 19" LCD Monitor. It went dark and when I unplug then plug it in it lights up for a few seconds then goes dark again. I paid $139.00 for the monitor, and when I queried the manufacturer, they said they won't sell me the part, but for $99.00 plus shipping they will repair the monitor. Since this would probably end up costing me more than the original cost of the monitor, I am surely not going to ship it to them. I have opened the monitor (I am fairly technical and a Ham operator), and I cannot find a separate inverter. It appears that the monitor has a single board. Does anyone have an idea as to where I can find a replacement? Any and all thoughts would be much appreciated.

I am working on a HP dv6000 with no display. It will power up, indicator lights are working, but no display. I tried the "flashlight trick" and tried to view desktop items under intense light, but nothing was visible. I believe the display inverter is bad, but I would appreciate information on any available testing procedure for this one before I order a new one. Any help?

Thanks in Advance
 

A:HP Display Inverter

if inverter is bad, you can still see the image on the screen. if you don't see, so there's lack of LVDS signal from MB to LCD screen. in this case, you should check connection between MB and LCD, and if your laptop has nvidia geforce7200/7300/7400 videochips or nforce 6150go video, you should repair this laptop via warranty service.
