Panasonic Plasma Power supply board

[danzr1]

I have a Panasonic TH-50PX60U that I identified has a bad power supply board as I determined using the service manual.

The power supply board model ETXMM610MEF/NPX610me-1, which seems to be slightly different than all the fixes I find online. Anyone ever fix one of these?

I've checked for a thermal resistor (doesn't have one) as per youtube video:

I've tried freezing the IC labelled TEA1610 as per video, even though my board is slight different than the IC TEA1611

What are the symptoms/issues with the board?

Oh ya, forgot the basics! The tv's red LED blinks 10 times when plugged in, and it won't power on. I believe there is supposed to be 14 volts output after measure on a certain pin, but I don't get any voltage.

The trick norcal showed in the video is useful but doesn't eliminate the P board especially as the TEA ICs are the cause of 95% of the 10 blinks problem. Sometimes the freeze spray doesn't give them enough of a kick. How good are your soldering skills?

I've been soldering for years. I have the service manual and followed it step by step to determine that it is the P board. Do you think its worth ordering a new IC?

Do you think just changing the capacitor next to that IC might help? I saw this:

Re: Panasonic Plasma Power supply board

I have a panasonic with this same power board. I get 7 blinks. I am stumped and don't want to just throw a power board at it.

Re: Panasonic Plasma Power supply board

7 blinks is not power board usually. It's SC, SS, SD or SU.

Re: Panasonic Plasma Power supply board

c/p...On a Panasonic TV the 10-blink error code can sometimes be caused by low voltage running through an HDMI cable, particularly from a Media PC or some video game consoles. Try disconnecting any HDMI cables and unplugging the Television for 30 seconds, then power it on without the cables attached.
