I have a 32" Elonex Lumina TV/PC combined media center . As soon as I plug it in to the mains it tries to power on. The screens backlights flicker on and off fast for a while and then starts calming down and eventually stays blank. While the backlights are flickering all DC voltages are doing exactly the same, but after 20-30 secs the voltages become stable around their expected values i.e. 24v=24.35v 3.3v=3.31v 6v=6.12v 12v= 12.4v and 33v=32.96v, the only one that seems a little low is standby 5v=4.45v
I am assuming the fault is on the primary side as all DC voltages are effected. I checked the caps and they appear ok apart from a high esr on one small cap which I replaced.
Could this possibly be down to the PFC(IP3002) or the PWM(Viper 12A)?
