Bugger! In the quuq downloads area, I've uploaded a service bulletin for diagnosing code 10. You may care to take a look at it.
Alternately, with the power supply board on the bench, apply a low current variable supply ( less than 2mA is all that is required) to pin 12 of MC201 or MC301. The negative of the power supply used should be connected to the hot common. The 3 white 0.1 ohm resistors in a row is an easy spot to connect to.
Increase the voltage and monitor pin 7 of the module. It will track the input voltage. Before you reach 15V, the module should switch on if it is functional, but it should happen at less than 14.5V. Pin 7 will output a square wave. If the module doesn't respond, you may increase the voltage further, but don't exceed 20V.
The higher the voltage needed to wake the module, the worse state it is in.
And another picky to keep the Turnip happy.

Hi Bruce,
Impressed - Looks like that former sub-panel from a distance - wish I had one, and when I do - will refer with some gratitude - Thanks - Chris.

You're welcome, to be sure, Chris. Panasonics can be quite a challenge since the error codes generally have to be taken with a grain of salt, and I'm sure a goliard such as yourself will know the meaning of that.
Samisat, let us know how you get on with this one. You have checked the SD card slot for refugees??

Hi million thanks for ur help.Unfortunately I don't have enough equepment but I will let you know by any news.

Hi Bruce,
Sure, I enjoy a glass, but am neither a poet nor an apologetic Theist.
Had myself a Sammy PS-50Q97HD in today with a popped top buffer chip, and chap wanted a cheap mend, and change from a small note - Quoted £200 plus possibly a new screen - he declined.
Would refer him to you, but postage both ways would be a killer - Chris.
P/S Realise advice from flashing leds indicates a problem - Ours to try 'suss' what problem is the current biz when there are so many options for most flashes.
