Panasonic TH-42PZ80U

[taxicap]

Howdy gang!

The symptoms: I'm pretty sure it started as a 7 flashing light error - but now - the tv will stay on for about 15 minutes until powering off and retreating into 8 blinks

have searched and found SS board is common problem on these units - tv from 2008! Would like to save it if possible

Have a little experience and wondering if someone would baby step me through a further diagnosis process - have a cheapy volt meter ---

here are the pics - please help me correctly identify any testing points and the SS board ---

THANK YOU KINDLY!!

I'm in Columbus Ohio. If needed I have the sc, su and sd board that came out of this model tv. All 3 boards work.
The tv had a bad panel.

Doubt its the SS more likely the Controller Ic and Ceramic cap fault on the psu IMO.

Most of the time the IC is good on both "sub boards".
I just solder in a new cap on each. Been working for me so far(4 months).
You dont have to mount them the way he does it in the video, do it the easy way, small wires soldered to the boards, soldered to the caps, them glue or zip tie to something that stays cool.
