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....

Hi I am new to this sites looks like alot of good info. Anyways I have a Acer at3201w lcd tv/monitor that worked fine then the screen just seems to have lost the picture. When I turn it on I can hear the audio from the input and the screen lights up as if it is turning on but no pic. Also the buttons on the front work sometimes. I have opened it up and could not find any visibly blown caps. I think it maybe the mainboard. I have found a replacement part but not sure if this is the problem, any help would be greatly appreciated. Thanks
