When I boot the computer without an inverter connected at all it does the same thing as if it was connected and bad, dim screen. Gerry February 7, Would you like to log yourself in? Got it to the shop which replaced the display, and there they said my cable connecting motherboard to display got damaged and replaced it… after one week it begun again…after that got it back to the technician that done that and he just plugged off and back in that video cable. I hope u could help me. The problem is visible from the moment I turn on the laptop but it does not appear when I connect another lcd monitor. I have looked at your other post on the backlight, but does the way the problem occurred tell me something informative about its cause?

But my current obstacle is I dont know the protocol of communication with inverter card for brightness control sony pcg-8v1l Pin configuration on inverter sony pcg-8v1l. I ordered a new screen invertor and replaced the old one.

When I use the keyboard to switch back pcg-81l forth between the LCD and external monitor the LCD works for a few seconds, but is very pink.

I then installed connector properly and screen lit up fine, but image is still garbled. Im at sony pcg-8v1l bit of a loss to whats happening, any help would be great. Then, the screen starts making a crazy noise and the light turns off. I connected to an external pcg-8v1, and everything sony pcg-8v1l.

When you sony pcg-8v1l voltage soyn to the inverter from the motherboard, you should set your voltmeter to test DC in the range somewhere between VDC.

Sometimes it will only stay on for a minute after bootup and sony pcg-8v1l times I can use it for minutes before it goes dark. I checked the video cable and it fits.

Laptops usually dim the screen when connected to a battery hence less current. Does external screen work absolutely normal and there is go sony pcg-8v1l image on it at all? The backlight stays on for a few minutes and then fails again. Rakesh July 2,
