Re: 7 blinks of death for Panny Plasma TV, Viera, TC65PST34
Success! Thanks a lot for all your help and advice, TVTIMMY, TW2005, TOM66!
It was a good learning experience. Vendor sent me a bad SD replacement board, I had to ask them to re-send. Also, I had really difficult time re-inserting 10 ribbon connectors into SD/SU boards, was finally able to insert it correctly.
Completed Steps:
1) TV stopped working with a loud pop; No picture or sound after that.
2) LED blinks 7 times in an infinite loop, which I identified as SC or SD/SU Board...

Re: 7 blinks of death for Panny Plasma TV, Viera, TC65PST34
No, I did not remove the SU to SD ribbon connector before measuring resistance. Now I did, and got the same result:[U] shorts in both SU and SD[/U], all over. I just ordered new SD and SU boards [$62 for both], but now I feel less confident, since you told me that this situation with both boards being bad is rare. I cannot check screen for cracks now, because the TV is laying face down. I recall, there were no cracks when I put it on the table 5 days ago.
What else do I need to check before the...Leave a comment:

Re: 7 blinks of death for Panny Plasma TV, Viera, TC65PST34
I am getting a lot of shorts, in both SU and SD, almost for every 3rd or 4th pin. What do I need to use for Ground? I currently use a spot where 4 screws are sitting that connect SU/SD with SC. I removed the screws before testing.
Just need to make sure I am checking for shorts the correct way.
I added a pic to show what I am using as Ground while testing pins on SU/SD. Please advice if this is a correct spot for Ground. Thanks....Leave a comment:

Re: 7 blinks of death for Panny Plasma TV, Viera, TC65PST34
Thanks, tom66.
Everyone, pls read my first two posts above in this thread and let me know if this is a valid plan going forward
1) get New SC board [already ordered]
2) replace the faulty SC board with the NEW one
3) while isolated from SU/SD boards, and using the SC jig, test the New SC board by powering the TV; If no blinks observed, I'll assume that New board is OK.
4) validate SU/SD [still need to learn the procedure]
5) upon validation in 4), hook up SU/SD boards to...Leave a comment:
