My Panasonic Viera 50" is reluctant to turn on. I turn it on

This answer was rated:

My Panasonic Viera 50" is reluctant to turn on. I turn it on at the set, but after that for an hour or so it blinks red light/green light before eventually going on. Any ideas? Has been doing this for three weeks.

Hi , I`m Jack
Perhaps I can help you with this problem , a few questions coming up

Once turned on and warmed up ( 1 hour or so) , can you turn it off and right back on normally ?

Hello ,

Sorry but i was out last night when you replied ,it was 11:15 PM here .

You did not give me the model number of the tv but the symptoms you described and the fact that panasonic hasn`t made a plasma tv for 5 + years tells me its not a young tv and what you have is a typical case of weak/vented capacitors on the power board .

Around here you would be looking at some $250 to have this repair in a shop .

If you are into this you could simply replaced the power board VS repairing it , that board usually cost somewhere around $100 but one detail on this ; the VS and VA voltages on the power board will have to be adjusted according to the values written at the back of your plasma panel , they are specific to each panel and it will be on a sticker .

You will need a voltmeter for this .

Again if you are into this then let me have the TV's model number and I`ll see what I can find otherwise if you are going to go for the repair shop or even a new tv then never mind the model number
