Hello all! As mentioned in the title of this post, all 3 HDMI ports and Video Inputs (1 & 2) are dead. The cable TV input is the only thing working. I was able to verify that I had a good signal by connecting to an LG flat panel display. I pulled up the self-check screen and all items are listed as OK with EPOP value of 200. I have done capacitor replacements on PC boards previously and own a digital volt/ohm meter. Any help on diagnosing this problem would be much appreciated!
