The blinking LED is a clue. Count how many times it blinks between longer pauses. Then, to really be accurate with my answer, I will need the full model number of he the set. It will be on the back.
If you can't get me the model, I can only give you a general idea of the problem.
Please let me know so that we can continue.
it flashes twice between pauses. My TV is wall mounted to I can not get the number. I purchased it in about 2009 though
Are you still on line to assist me?
Assuming that this is a 10th gen Panasonic Plasma (which I can only assume from the date of purchase), 2 blinks is a loss of +15V DC on the power supply board.
It is often the power supply board (P Board) that is bad but it could also be the
D, H, PB, SC, SS, or DG boards.
There is a troubleshooting routine to determine which board is bad. I can walk you through this as I do with many of my customers. You would need a good multimeter that can measure volts and impedance and some basic tools. The back would need to come off the TV.
A typical board is about $100-$150 and that would be your total expense. If you decide to call in a tech, you can probably double that at least for parts and labor. You can find a tech at www.tvrepairpros.com
The TV will have to come off the wall. When it does, grab the model number so that I can revise my answer if necessary. I w ill be happy to help you for as long as it takes.
I'm sorry that there is no quick and easy fix for this problem. You definitely have a board failure inside the TV.
I'll be here if you need further help with this issue. Please let me know.
I will have to bite the bullet and call a tech and get an estimate. I may just get a new TV if not too much difference in cost...thank you...Bud
