About 6 months ago, a small spot appeared on my IBM R40 laptop TFT screen. This spot grew in size to about 1inch dia. Now there are two such 1 inch dia spots on my screen at different places. The 2 black spots look like cells of ink have burst. Can you please urgently advise on whether I can self-handle this and how or whether I would have to give it to an IBM/Lenovo Service Centre for screen replacement and the cost approx. or other suggestion please. Thanks. Karl Lobo

If your laptop appears to boot up and the hard disk LEDflashes, then the problem is probably a back light fault. This can be a faultyinverter or a faulty CCFL lamp. Please click on this link and follow myinstructions to identify the fault and possible fix :-
There are a few options as far as what could be going wrong but unfortunately whatever it is, it won't be good. The options are: video card (probably onoboard, if this is the issue the whole motherboard will need replacement), driver board for the LCD display (cheaper fix) or the LCD itself (probably not the issue). The only way to know for sure is to take it in to a place that fixes laptops and have them look at it. They can order the part you need and install it for you or at least check it out and give you a quote. If it's the motherboard it would be better just to buy another laptop instead since it might cost up to $300.
There's a very low chance it could be driver software related but this could only be the case if it does it ONLY after starting windows and during the welcome screen. If it does it during that black screen with white writing when it boots up, then it's hardware since at that point no drivers are loaded.
Usually we can see these type of spots, if we place any magnetic field next to a CRT monitor. Try removing if any speakers or its power adapters or any radiating devices near to the monitor. It will get ok after a while.
If still the problem persists contact a service center.

Hi, During the boot at the THINKPAD SCREEN press the Thinkvantage key ( Blue button ) it will launch rescue and recovery and allow you to reboot factory. This only works if you did not corrupted/deleted the rescue and recovery hidden partition on the HDD. Otherwise you will need the rescue and recovery CD to proceed. IBM/Lenovo support should be able to provide you the CD. thanks and have a nice day J-
I think you have an inverter board thats just about dead. It's located in the screens plastic housing at the bottom of the screen just above the keyboard. It's about 4 inches long and a half inch wide.There's just one little cable connecting it. But you have to take your screen apart to get to it. It's easy to replace and relatively inexpensive but it does require a little disassembly skill.
Also ,I will need the exact part number from the bottom of your laptop. There are several different R 40 models, and 2 different screen sizes.
Did anyone try to dry up the liquid inside? I've seen customers machines that had wine spilled in them and last a month before finnaly shorting out the system. If you're lucky a tech may be able to recover the data off the hard drive.
ccfl ( cold cathode flouroscent lamp ) is the backlit feature of the lcd panel.
If you see a blank screen but do see the output on the external monitor then you sure have to take it to the hardware tech to get the inbuilt LCD panel checked.
it seems to be a electronic failure.
