Panasonic TH-50PX60X

Symptoms:
The set turns off after a few minutes of use.
LED blinks 4 times
per service manual - I measure 0V (before shutdown) at pin 16 of connector P25. Indicating faulty D board PN TNPA3820ACS. I measure 1.7V after the set shuts itself down.

Anybody have any experience with this problem?

New discovery. When I plug in an HDMI cable, view a movie it shuts off as before but now the led blinks 10 times.

I'm going to run through the diagnosis flow chart for 10 blinks as well as see what happens with no inputs and it shuts down.

4 blinks is usually power board over-voltage. Check VSUS and VDA output voltages to see if they are excessive.
