OK, there seems to be some confusion about this board and what I have done to it so far. The 4 capacitors in the 5 volt and 12 volt supply have been changed out during "parts cannon" day. The two tall black ones are 470 uf/25 volt Panasonic caps, replacing C915 and C922. C915 was 470/16 and the old one currently checks at 441uF. C922 was 470/25 and the old one currently checks at 458uF. These two black Panasonic capacitors will stay in place. The red one is a 330/16 volt "Wurth" capacitor replacing C917. The old C917 currently checks at 345 and will be put back in the...

I have been going round and round with this one for a couple of years. It's a 16x10 display that allows you to size your OTA picture correctly to 16x9 and that makes it kind of cool so I really want to keep it on my OTA monitoring wall. Accidentially let a screw roll under the powered power supply board and ended up replacing the MOSFET drivers for the inverters, then one of the Schottky rectifiers for one of the supplies, then the PS caps becuase I fired the parts cannon at it one day.

Problem was no cold startup; it would only startup when you applied a heat gun to the board....
