Hi folks - yes I have a Panasonic Viera which for 2 years behaved perfectly then started to ‘not respond’ when reconnected to power. My thinking was that I needed to power down on occasions to prolong the life of TV but that seems like a bad idea with these TVs because you cant get them to go again! - no lights, nothing - googled it of course and tried all the fixes which did work - my point is that the first occasions I booted again by disconnecting from power for 30 + secs reconnecting then pushing power button — later for longer periods and then adding a program or volume button. The last time I waited '''''3 days''''' and periodically tried the combination of fixes - this time I waited '''''5 days plus 90 secs disconnected from power'''''.
So be patient and don’t buy a new TV yet - that is if you can be without it for lengthening periods - I just wont risk powering down from now on - I’ll let you know if this all means slow death TV and no more Panasonics for me. Share if you agree.
