Thanks
and we look forward to assisting you on your TV repair journey.
In this video we are going to go over a troubleshooting method you should try first, if you have a
fourteen blink code on your Panasonic Plasma TV.
Here is a list of models that this troubleshooting method will work for.
We will show how to test for a short in a few different lines on the power supply board.
When checking for continuity, you will want to set your meter to ohms and then put your
negative lead on the chassis and you positive lead on the test point.
You will know your board has a short if your meter shows zero ohms or a number that is
close to zero.
When using your meter to test the pins on the connections, the only pin that should
show up as a short to ground is the pin that is labeled ground.
Not every connection will have a ground pin, but if you see that, it is normal for that
pin to show up as a short to ground.
The first place to check is P2 on the power supply board.
If pin one was shorted, and showed zero ohms, you would want to disconnect the line form
the SC board and re-check the pins.
If the pin is still shorted, without the line connected then you will need to replace the
power supply board.
if the pin is not shorted anymore, then you will want further troubleshoot.
Further troubleshooting the SC board, you will want to disconnect this connection and
then disconnect the ribbon cable as well, then go ahead and check the pins here
