Well I got everything working .. looks like it was indeed just
corrupted EEPROM settings. So after getting into service mode with the
mute+1+8+2+power_on I used both the info from
http://schforfree.seedhost.com/archi...deo%2FProducts on the
samsung chassis KCT52A as well as a bit of luck and managed to find a
working set of numbers for the option bytes, specifically byte0: 20
byte1: 554

Since the chassis manual seems a bit dated the info on byte1 didn't
jive completely but I now have audio and video like normal, so I am
happy. Thanks to all that replied.
