Question about IBM ThinkPad T23 Notebook

1 Answer

IBM t20/t23 Hi - I have a T20 that went dead (bad mother board I'm told) last year, so I got a used T23. After a few months, it's screen started flickering, then finally went almost totally black (I can barely see the image of the desktop so I know the machine is running, just can't DO anything since it is too black). Can a non-expert (I'm tool handy, just not a laptop geek)take these things apart, then move parts (video?) from the dead T20 to make the 23 work again? How do I know what to move? Thanks... Bob

Hey, Laptops are very fragile and sensitive components! If you feel that you are capable of task like this then godspeed! Something like that could be three things! 1.) Your screen inverter has gone bad! The inverter is the device that provide high voltage power to the lamps in your screen! 2.) The lamps in your screen are bad! These things are usually rated for like 50000 hours. 3.) It could be as simple as servicing the laptop(cleaning up the contacts and ensuring good connection) Laptops come in all shape and sizes, and worse some come with a thousand screws of different sizes! It should be relatively easy to take down but the hard part is putting it back together. I have this friend who, after he re-assembled a laptop, always has extra screws!! He says the laptop don't need em! LOL What i would suggest is moving the entire screen, that way you don't have to take it apart to get to the inverter( should be the only other device located in your screen aside from the actual LCD(the lamps are in the LCD) The models sound very similiar but not sure about them either, it the screen looks the same then you can change it! Practice taking down the t20 first then if it breaks you'll know how NOT to break the t23! lol I would always recommend getting a pro to handle something like this though, cause is very tedious you have to be real careful! Best of Luck! regards, babb

Hi..i am using compaq presario cq 40 and screen is flickering.i had it checked and they told me lcd is the problem but they didnt even bother to check.they just turned it on and they told me that i have to...


When it flickers, can you still see the text when the screen goes dark?
May have to use a bright flashlight set right on the display to see
the text on the screen beside where the light sits.
That will tell you if it's the backlight.

You can also look at a grazing angle into one of the edges to see if the
backlight is flickering when the display does.
When it's cold, does it start with a slight pinkish color? That can be
a sign of backlight going bad.
Anything interesting happen when you flex the cable by moving the screen?

I'm not saying it's impossible, but I've never seen software cause
consistent screen flicker. And if the vga port doesn't flicker, sw is
even less likely the problem.

If you bet the odds, you'd bet on a bad display cable.
Won't hurt to try replugging it.

If that doesn't help, then your monitor may be dying....

ThinkPad T23 white screen


1. your issue may be a bad hard, a damaged or loose flex cable to the LCD screen, a defective CPU (central processing unit, a cmos battery that needs replacement ( this is the battery that retains the information for the motherboard), a bad power supply regulator on the mother board.
2. this is just a few of the issue that have caused a white screen.
3. Laptops are mostly disposable and are usually good for 2to 3 years of service depending on the care taken.
Your friend probably thought he was helping by giving this to you to see if you could use it or part it out.
Not worth the work unless you are into PC repair or project work.

When computer is turned on screen stays black and fan races fast


If you put it in another T23, Windows will recognize the hardware change and ask you to re-activate Windows. Microsoft may or may not require you to pay for Windows again.

IBM THINKPAD SCREEN DEAD


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.
