Question about Proscan Televison & Video
I have to unplug the cable to the tv and let it get warm because as soon as the picture comes on it shuts off. once it gets warm it's fine
It was a common problem with an lcd tv, usually a leak or bulged capacitors in the power supply board will be the caused.

This depends on whether you have digital cable box or not. If you have a Digi Cable Box look for the red/white RCA output and connect this via RCA cable to the Red/White Audio input on your surround.
If just Basic Cable look for a red/white audio output on the back of your televison. connect this to the Red/white in on your surround. Could be called tv in or auxillary.

Is the HDMI port 2 work? Try to turn it off and turn it back on. If it is still not working then the HDMI ports have gone bad. You will need to replace the main board.

I had this exact problem on my Vizio 47" HDTV. I removed the speakers and all the screws on the back cover. Took the cover off and located the fuses on the largest circuit board. The are in the upper right hand corner of the board. There are 3 of them in a row labeled LF 1.5, LF 3.0 and LF 3.0. The are white in color with copper ends. I took a volt meter and measured continuity across all fuses individually and found the LF 1.5 to be blown. The guy at the electronics store sold me a barrel 1.5A fuse and told me to soldier it across the top of the blown fuse. It took an extra set of hands but the TV works perfectly.
