Re: tc-P50U50 power on, all white screen
i should also add that as soon as the tv is powered on, it shows a black powered on screen for half a second, then resumes to the solid white screen.

Re: tc-P50U50 power on, all white screen
i have sound.
it responds to the remote control.
the pattern test does not show up (and i tried to factory reset from the service technician mode), however i am doing it blindly as there are no menus.
I have attached pictures, but nothing jumps out at me. I can see that the SS board has had the upper resistors replaced that are attached to the upper heat sink (visible from underside and a very common problem on this set). Nothing else looks bad.
Thanks for all of your help! this is the first time i have...Last edited by xxsuperstreetxx; 09-25-2016, 09:23 PM.

tc-P50U50 power on, all white screen
I have a panasonic plasma. It powers on and has an all white screen. When i change inputs with the remote is goes a tiny bit less white on one of them but bright none the less. No menus are present. i have tried to reset the tv. The SS board has been previously repaired. There are no blink code errors.
Any idea what is wrong?
I checked all screws to look for any loose ones, and reseated all cables.
Thanks!

Re: Panasonic TC-P50X3 14 Blinks.
Any idea what chip could be the standby cpu rom? (there are two chips under the heat sink).

Re: Panasonic TC-P50X3 14 Blinks.
Thanks for the reply. I did what you described to isolate the power supply and main board from the rest of the components. Same error code, indicating it must be one of these two boards. Based on panasonic's repair guide the cpu on the main board might be the problem (see pic). I am thinking of heating up some the chips in an attempt to "reflow" any solders that might have cracked. Maybe this will fix the problem as no visible issues can be seen. I don't have anything to lose as i can't find a replacement board for this tv and they are...Last edited by xxsuperstreetxx; 06-28-2015, 10:21 PM.

Panasonic TC-P50X3 14 Blinks.
Hi guys, my tv will click three times when plugged in, then will result in a 14 blink code. 14 blinks is defined as: "14 blinks -> Loss of F15V from P bd. P6/pin 10 or A Bd detection."

Here is the diagram of the tv internals
I am a novice at repairing plasma tvs, and do not have a volt meter. Checked physical connections from P6 to A6 and seemed fine. Wondering if trying to change the main board is the best bet.
Also I have a tc-p50x5 with a cracked panel (Panasonic MD50H14C1A Display part number). The internals are different than the...Last edited by xxsuperstreetxx; 06-27-2015, 05:20 PM.
