Panasonic TC-P55ST60. 7 flashes

[planky]

I have a Panasonic plasma tv - model # TC-P55ST60. I bought it from Sears in May 2013. A few days ago it shut down suddenly with the power light flashing 7 times in sequence. I have changed the P, SC and SS boards (bought from ShopJimmys) with no success. Would appreciate any suggestions/assistance with trying to trouble shoot the problem and arriving at a solution

Could be bad SU/SD boards. Can you supply pictures of the parts inside the set and one with the whole back cover off?

tom66,
Thanks for your quick and helpful response. Both boards are in fact on order and I hope to receive and have them installed in a few days. If this does not prove to be the solution, I will forward the photos suggested .In any event, I will be in touch again a.s.a.p. Thank you again!

Er... are you aware of the possiblity of testing them? "Could be" is not a DEFINITE...!

Also you can get bad SU/SD which can DAMAGE the SC board. So it is important to know if they are all in working order.

How do I test?

Please supply clear photos of them. You will need a digital multimeter.

You could have pulled off the su and sd boards first and tested the sc board with a jumper. I have seen su and sd board's damage the sc. As.a matter of fact I just repaired a 65 inch the same way.
