Panasonic TX-P50U30B power issue

[ag63kry]

Hi
Got my Panasonic plasma tv that stopped working suddenly.
Took out the cover all the leads from the powr baord in the middle apart of the main 220AC. and measured Vsus and 15V DC on P2 and P11 connector. Found nothing. Concluded it is the board
Replaced with a second hand one but still the same issue.
Cannot see the 5V or the 15V on the board with or without all the other leads attached.
Here is an example of what I have measured on P6 connector (see the image).
3V DC on pin 6 (STBby 5V and
0,3V DC on pin 7 (F_stdby_on)

No lights on LED, no ticking sound or buzzing.

Please help
Could it be the main A board? I was expecting to see the 5V and the 15V DC on the power board even if the A board is defective or disconnected, am I right?
Any ideas anyone?

Hi. Thanks for that.
Issue now solved , changed the A board, all ok.
The only thing is that I have au automatic menu activated when I start the TV- see picture. Even if I press exit, the red info (setvice mode info I guess) remains on the screen which is absolutely annoying
Anyone have any idea?
Thanks

Hi. Thanks for that. It does not work. It all starts when I turn on the TV . It says <Start adjust menu> and then the attached picture is displayed. If I press exit, it is gone, but stiil the red service info remains at the left side of the screen. The remote control does not also have a Menu button , otherwise I would have tried to factory reset it.
So stuck here, no idea what else to try

Press and hold the “V-“ on tv and press the «menu» button on the remote control. After that , turn off the TV with the power switch .

I don't have a Menu button on the remote I bought the TV with. I will order a new one if that is a working solution. You sure you are this will work?

Thanks

Turning off the TV with the power switch does not help to exit the service mode ?

Hi. No. It always goes to the same menu. I have also tried to leave with no power for 60 minutes, no difference

Someone managed to exit the service mode like this: press and hold "V-" on the TV and press "OK" 3 times quickly on the remote control, and then pull the power cord out of the socket.
