Question DetailsAsked on 12/30/2014

My Panasonic Viera tv just turned off for no apparent reason and will not come back on..

Model number is TC-P55VT30, Panasonic Viera, two years old. Just shut off unexpectedly and will not come back on.. The only thing that happens is the power button, to turn it on, will blink 7 times, then pause and blink another 7 times. Keeps doing that, but will not turn on. Any ideas?

If you Google this search phrase - Panasonic 7 blinks - you will find tons of complaints on this problem - known as the "7 blinks of death". Evidently this is a very common problem with large Panasonic TV's, Viera's in particular - commonly dying at 1.5-3 years of use even though Panasonic advertised 30-40,000 hour life for the TV. Unfortunately, many manufacturers claim a 30-40,000 hour life for LED's (which may or may not be true because in most cases they extrapolate life over a short period or a large number of test LED's to a much longer period, which is phony statistics, plus that ignores the fact most electronic circuit boards of basically any type last nowhere that many hours of use.


The problem MAY (depending on source you read) have to do with the Contrast being set too high, burning out one or more of the scan drive boards (which evidently cannot takethe higher power demand even though the contrast setting can go that high) - also a problem with HP computer monitors, BTW.


Here is a link to an article -

stating (as severalother blogs and comments said) there is a "silent" warranty extension for this problem, which Panasonic will pay for IF it turns out to be the SC board that is the problem. Unfortunately, if that is NOT found to be the problem, then the total diagnosis and repair cost is on you - web postings indicate $400-600 common repair cost depending on how many boards went out - commony SC board, but evidently sometimes takes out the SD and SU boards, and sometimes the overload thermal fuse on the power supply.


Therefore, a lot is at risk if you go ahead to have it fixed - especially as you can buy another brand (image quality you would have to see at a store) from LG, Vizeo, Samsung, etc for about $400-600.


Obviously, if Panasonic does not come through for you with a free repair, sounds like a review somewhere is in order - unfortunately, AL does not allow product reviews and you will not find a local listing for Panasonic, so you wouldhave to post it elsewhere.
