    thinkpad t30 screen goes blank

    Hello,

    Just two days ago, my Lapi screen started going blank. the lapi is on, but the back light goes off.

    When plugged in an external monitor, the screen displays fine.

    I have 1GB Ram, 80Gb hard drive and installed windows xp.

    Research from google shows that most people says its the inverter, others says its not the inverter. but screen.

    Any suggestions

    Does the display have pink/red-ish tint when cold, which goes away when it warms up?
    if so, it's the panel (actually the CCFL tube inside).

    If not, it's most likey the inverter.
    Set windows up so it doesn't go into standby (or whatever) when you close the lid (screensaver properties page).
    if it comes back on after you've closed the lid for a bit, the inverter is suspect.

    Also check if you can see anything on the screen when the backlight is off by using a flashlight/torch. Works best when playing a video with lots of movement in it in fullscreen mode instead of a static desktop.

          if i use an adapter with slightly higher voltage rating, can it affect it,aking it behave this way?

            Lenovo Thinkpad X1 Gen 10 - Flickering Screen
            by Ado02
            Hello everyone,

            We recently replaced the OLED screen on a Lenovo ThinkPad X1 Gen 10. After about a month, the replacement screen began to flicker. Initially, updating the Intel® Iris® Xe graphics driver resolved the issue for about a week. However, when the problem recurred, updating the driver again had no effect.

            The flickering only occurs once the system reaches the Windows login screen. Interestingly, if we disable the Intel GPU driver or connect the laptop to an external monitor, the flickering stops. We have tried installing two different replacement screens,...

            Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
            by Ryan.man
            Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

            My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

            This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

            ThinkPad P15s Gen 1, NM-C931 REV 1.0 touch screen replaced only works in UEFI menu
            by Yehuda170
            original screen was BOE NV156FHM-T07 with On-Cell Touch screen I²C

            replaced with what was in my stock, which is IVO R156NWF7 R2 which is also with On-Cell Touch screen I²C

            now touch screen works perfectly in UEFI BIOS menu & boot menu. but not working in OS, tried windows & linux too

            with original broken screen i can see in device manager touch screen in human interfaces

            but with the new screen it's not showing in device manager

            is it lenovo blocking it? is it driver missing?

            I²C is a headache

            HP Elitebook Screen blank - backlights but no image
            by dicky96
            Hi guys
            I'm trying to fix this laptop screen

            Basically the owner is a computer shop and they brought it to me with two screens. They said the repair shop they use could not fix it, so I thought i would try to see if I am better than their current repairer!

            OK so I have the original screen which works but has lines across the bottom quarter of the screen

            I have the replacement screen, which they fitted and it worked. They then put the laptop on one side for a couple of weeks until they found a buyer. When they showed it to the buyer, the screen would...
