Hi,

Since you have replaced the inverter and the unit works with an external monitor, then probably problems would be with:

  • CCF lamps (backlight);
  • inverter triggers and/or B+ supply.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

My thinkpad makes 1 beep followed by 3 more other beeps. Nothing shows up on the screen


I'm fairly sure this means there is some error in connecting with the screen, maybe a cable worked loose maybe the screen is dead, or maybe screen inverter or backlight dead.

if the screen is dim and the images still display it means that the it's probably the CCFL tube or the inverter (located in lcd panel) it will need to be replaced.

My IBM T40 boots to a black screen with the "z"(light at top to right of power.


Try these steps:

1. Remove battery and unplug AC adapter
2. Press power on button for 30 seconds or so (one min is also too)
3. Attach battery and plug into wall
4. Power "ON" as normal

If you are still getting the "Z" and a black screen then I would have the video card or hard drive looked at and replaced. Start with the video card and then look at the hard drive

Hand-me-down IBM Thinkpad 600E 2645 has blinking LCD video XP O/S


This sounds to me like either your flourescent lighting tube is beginning to go bad ,,, or the inverter is going bad ... or even both. :-)

The cheapest and easiest solution for you is to simply replace the LCD screen (replacing the inverter or the tube are actually a bit cheaper, but not quite as easy to do - most computer repair centers will try to talk you into a new screen anyway). This is actually very simple for either you or someone you know who is an avid "do-it-yourselfer". IBM makes ity very easy. You will find easy, detailed instructions in the ThinkPad 600/600E (2645) Hardware Maintenance Manual, IBM S10L-9619-03 June 1999 available for FREE downloading in .pdf format on IBMs website. Follow this link to some really sweet deals on LCD screens for your 600e on eBay for under $35.00. http://shop.ebay.com/items/?_nkw=ibm+thinkpad+600e+lcd+screen&_sacat=0&_trksid=p3286.m270.l1313&_sop=12&_dmpt=Vintage_Electronics_R2&_odkw=IBM+tube&_osacat=0

Remember you can always connect an external monitor to your ThinkPad until your new screen arrives if you have one. The manual should also give you instructions to change out the tube if you wish to save a few more bucks and try that route. Hope this will FIX-YA! Please leave your feedback and let me know!

Ibm thinkpad t43 backlight inverter issue


Did you say the the video output flickers on and off when you connect an external monitor to the video output. If the inverter is faulty this would not affect the video output and the external monitor would not flicker but if the external monitor flickers it would point to a video card problem.

Laptop screen goes black, no backlite


You could have a defective screen - a defective inverter or a CCFL lamp.
To determine if you have a LCD screen or video card problem, read this and follow the instructions.

Defective CCFL backlight, it may have the following symptom:
  • Screen flashs on red/pink and off.
  • Picture stays on in red and slowly be come normal.
  • Picture flickering with dim display or appear black.
  • Picture flickering on and off.
All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Problem with ibm thinkpad r40


The IBM beep code error 1 long 2 short beeps means there is a video card fault. Reseat your RAM because the video card uses some of the RAM. If it doesn't work then the video chip on the motherboard is faulty, the only way to fix is to replace the motherboard - this may not be a cost effective solution.
Connecting an external monitor to the laptop won't work because the video card also sends data to the video port.

IBM T40 Laptop screen goes black, will not come back


First of all, you have to check whether you can see video signal with surrounding light tilting the screen.
If you can see dim image, all you have to do is replace back-light inverter or fix it. Usually, the fuse is open and you can connect it by simple soldering.
If you can't see dim image, it is another problems.
Give it a try.
