Re: Panasonic tc-p65s2 dead 10 blinks

finally able to get back to this !!! thanks again Tw2005 for all your great help !! just want to clarify some points before i send SC for repair.

summery of where i am in respect to this tv.

1) SC board is faulty plan on sending to Moduslink for exchange/repair

2)wanted to ensure that SD and SU boards are not faulty , I am going to check that none of the pins on the ribbon cable are shorted to ground, but I wanted to ensure that I am talking about correct pins/ribbon cable.
these are the cables that connect SD/SU boards to SC board correct ?? Currently I have Sc board removed and ribbon cable between SU and SD disconnected, I see pins on connector SD 46 (pins 3,5,7) are shorted to chassis ground(screw fastening board to chassis), rest of pins are at 30 Meg or so

Faulty SD board as well as SC ??

thanks

Post #8 has some docs, download G20 series and go to slide 44.

so long as the above are not short or greatly different(lower) I would assume they are ok. traditionally Vfo will go short.

here's a spreadsheet I did on 3 board sets. 1 good, 2 x bad
