I changed the power supply board and it does the same 10 blink code, what can be my next steps ?
Expert:  Pete replied 3 months ago.

Hi Emmanuel,

A 10 blink error code on your Panasonic TC-P46S2 plasma TV can be caused by a fault detected in one more more of the following areas:
Sub 5v SOS / Main 3v SOS DG Board
DTV 9v SOS / Tuner Power SOS

You will need to check you definitely have the correct voltage outputs from the power supply board first, then troubleshoot other areas of the TV circuitry.

I understand, that is what was posted all over the net, but now what connectors and what pins do I have to look for. I don't have the block diagram of this TV. Can you help me on that?
Expert:  Pete replied 3 months ago.

Yes, you can get the service manual and block diagram from

Hi, just checking in on your question, do you need any further assistance?

Customer: replied 2 months ago.
To be honest, this is not really what I excepted.
I thought we would have a one to one conversation or chat and figured out the issues together.
I did not think I had to understand in depth the 109 page service manual and figure out the issues.
I did not have time to look @ the block diagram. I will try to look @ this this weekend.
The answers you gave me are the same I could find on the internet before posting to this web site.I will let you know probably next week.
Expert:  Pete replied 2 months ago.

We can certainly reply back and forth and have a conversation on this topic.

However this type of troubleshooting is always best solved through carrying out the voltage checks to narrow down the affected area.
