Hoping you guys can give me some guidance on what my problem is. Thanks

Re: Panasonic TH-50PX500U

The power light stays red, no blink. Unless it needs to be interrogated?

Is it still displaying a picture? Is it frozen?

Re: Panasonic TH-50PX500U

I'll take a punt and say D board. You won't get a SOS blink with that kind of fault. D or DG boards but I have not really worked that kind of fault. It's definitely not Sd/Su/Sc/SS/PSU/ C boards.

The display isn't frozen. It functions properly just has the bars in front.

D board is a likely cause. You can check the on board test pattern.

SM for PX50U, a similar model:


page 39

Test patterns somewhere there - can't remember exactly how but think it's a few presses of the buttons to access it. Power off to exit.

Re: Panasonic TH-50PX500U

I initiated the self test yesterday and these were the results....

UV OK
SND OK
ADV OK
MEM OK
DT1 OK
DT2
OK
AVSWV OK
AVSWA OK
QC4P OK
RTC
OK
HDMI OK
PANEL OK

SOS: 8


I initiated the test two additional times and did not have the SOS code. I haven't found in the manual yet what that means but still looking.

Re: Panasonic TH-50PX500U

SOS 8 is SS board MID voltage low or electrodes disconnected/loose. Has the TV ever failed to turn on, with a flashing red light 8 times?

Re: Panasonic TH-50PX500U

No it turns on every time and the light has always stayed solid.

Re: Panasonic TH-50PX500U

Thinking about ordering a D board and an SS board and give it a try. They aren't that expensive so what the heck.

Re: Panasonic TH-50PX500U

I wouldn't order an SS board if the 8 blinks does not occur. Chances are the SS error could be original from the factory when they did the first test. (It obviously failed so they exchanged the SS board before shipment.)
