No Picture

[wwizardone]

I have an Acer Lcd tv Model AT3201w. My problem is that when i was watching TV I left the room for a few minutes and after returning the screen was lit up and i could hear the sound but no picture. I have opened it up and could find no blown caps. I have also checked the fuse on the TCONN board but it appears ok when i do a continuity test on it. Also I have hooked it up to different inputs and still just sound but no pics. The PS to me appears to work or the sound and the screen would not light up and the audio board appears to still be working, leaving me with the input board would be my guess. But I am no expert and any ideas would be very helpful. Thanks....

Post some pictures of the boards using "Manage Attatchments". The backlight could still be your problem. The inverter board(s) give you the voltages for the CCFL's that light up your screen.


Here is a service manual/troubleshooting guide I found for this set online.
