I'm sure you did this but the picture of the PC side shows a solder connection blown loose with the number 912 going to it. Did you check the resistor and resolder that connection? Just curious.

C912 is likely some sort of "snubber cap" for the primary of the SMT transformer.. Somehow I missed seeing that. R912 is on the supply line to the chip...if it was open...you would NOT see 171 volts on the chip...but check the connections anyway..
And YES...IF that cap is not connected...the PS may NOT run at ALL. Not sure EXACTLY what the voltage on the hot-side of the opto should be.... withoust seing a manual...BUT it WILL NOT be high...likely 12 volts or LESS...on BOTH pins..

checked both c912 and r912. both connected well. not sure how to test them. i'm assuming the board would need to be powered but not sure what meter setting to use. still trying to get used to this whole meter thing. the solder on r912 just has two different appearances. shiny and dull surface, im guessing made it look like it had lifted. any ideas?
rca2000, i have the pdf service manual if you want me to email it to you. Last edited by pac.attack76; 08-21-2015 at 07:36 AM.

I guess i'll just order the chip and optcoupler. Chip is $16 shipped. How do i look up the optocoupler? I'm 3 days away from ordering so i just have to figure out what to do. If this doesnt fix the no power issue, then i dont know.
