Panasonic th-42pz81B 7 blinks-sometimes

[steviewonder]

Here's possibly an interesting one..
Had this set brought along with (apparently) 7 blinks,however having tested the set it appears to work perfectly,so would seem a intermittent issue.
I have removed the ss board,(tnpa4410),had a study as was expecting dry joints-seems not at a glance.
Anyone had this peculiar issue before?

no not exactly but I think you meant SC board. Have you check the voltage levels that are monitored by the SOS 7 cct? Could they be close to the thresholds?

Reseating all the connections maybe on the SC including the sc20 may be worthwhile.

I have a 42X20 which randomly shutdown on a 7 blink. Nothing failed, boy was on his PS3, it came back on after a reboot never happened again that was weird.
I got a TNPA4782 SC board I repaired, something is amiss with that. Turns on fine but has small amount of maldischarge, if I go into serv tool and hold the return button on the remote forcing the TV to reboot from hot it goes 7 blink. turn off then on and it will turn on no blinks?

None of this helps you except to say strange things go on. Could be nothing wrong and the SOS 7 cct itself maybe the issue?
