Hi, I just built a pc running Windows 8.1, an A10 7850K processor, 8GB 2400mhz ram, and a FM2+ motherboard plugged into my TV, a Panasonic TC-L32X1. Up until yesterday I was displaying it on HDMI until I pressed something wrong in Catalyst and lost all display. The only thing I see when I start it up is the BIOS flashing on the screen, then the windows logo, then the picture is lost. I tried other HDMI outlets on it and still got no response. I can output a signal to the TV as well as a monitor fine in VGA, and can even output in HDMI on a different TV, but I still get a black screen with my TV. I reset Catalyst as well as my TV to factory settings and still got nothing. Does anybody have an idea of what's wrong?
Have you tried to run the PC through the DVI port on the tv, if there is no DVI output on the PC, look for a VGA port, if there is, buy an adapter (VGA to DVI), if there is not,I have no idea. Good Luck!
