    Try it in a darkened room. If there is NO light coming from the screen you have what is often called the 'two seconds to black' problem. It could be a problem with the inverter, the CCFLs, or even the wiring to the CCFLs.

    If there is still some light coming from teh screen, I wouldn't even hazard a guess.

      i think its the CCFL because before it turns off i hear sparks sound from the top left of the LCD.

        Either CCFL or wiring. It's time to start disassembling it until you find what's arcing. If you need help, post pictures of the problem area.

          Lenovo Legion 5 high fan spin turns off after 34 seconds
          by twonk9098
          Hi all,

          I have a Lenovo Legion 5 with a Ryzen 7 series CPU and RTX 3070 GPU. My issue is that it turns on and all seems fine except after a few seconds the fans spin up high and the laptop turns off after 34 seconds.
          I can get into bios and can even boot and login to Windows however after 34 seconds no matter if Im at the bios screen or booted into Windows it will just turn off.

          I have managed to run HWmonitor and the temperatures of the CPU and GPU are fine, I can also touch the heatsync which is warm but not hot.

          I have tried a few new bios but exactly...

          Lenovo 15iml05 Power led lights for 12 seconds then off 12 seconds
          by liquidzorch
          Hello. I bought a faulty Lenovo ideapad 3, but it turns out the 3Valw buck converter burnt a hole through the board. I was able to clean it up, and remove all the shorts. I now can power the 3.3v rails from a bench power suppy while connecting the laptop to its psu, and I get the additional 5valw, 1.8v, and 1.05v, form what I can tell in the schematics, those are the only 4 voltages I should see before turning on, and they are present. When I hit the power button, the power indicator on the left side turns on (not the one on the power button), stays on for about 12 seconds, then turns off for...

          LG 23MP55HQ LED Monitor turns off after a few seconds or flickers.
          by Rick_1234
          Good evening, gentlemen.

          I have a problem with my monitor. It turns off after a few seconds or flickers. Shining a flashlight on the screen doesn't show any image, so I guess it's not the "2 seconds to dark" I read in the forum.

          To turn it back on, I have to press the power button twice. Then after a few seconds it turns off again or flickers. See video.

          Harman/Kardon AVR 645 returning to stand-by after a few seconds.
          by PowellSkier
          A Harman/Kardon AVR 645 repair has been a hobby of mine for the past several years. My latest attempt involved the purchase of a DOA unit for part swapping and testing. The original AVR would power up then shut down after a few seconds. I completely tore down both units, found a couple of bad components and reassembled one of them. Same issue, no speakers connected. After extensive research I found a repair document from Harman/Kardon that explains the protection circuit in fantastic detail and provides specific test points for each fault (power, DC detection, overload & power) and the voltage...

          Philips 243v5lhsb00 Monitor Picture too bright
          by Schwoin
          Hey everyone,

          the picture on my philips monitor looks way too bright so that black appears grey and colors also seem too bright.



          While i tried to tilt the screen a little bit while it was displaying a picture, iยดve noticed, that there appeared some purple pixels. In the following picture
          you can see them on the top half of the photo.



          At a certain point during the tilting, the picture looked normal again but as soon as i laid it back down, the purple pixels were gone and the picture was bright again.
