So I can confirm its not the A board
All voltages stable from the P board
The output from the Ld board to back light pulse up and down
with or without back light hooked up. I took a plunge and split the screen ( I have done many phones) and all leds look OK.
So now where is the best place to find parts the 2 local shops haven't been to keen to order parts in before for me

So what have you decided, LD board?
Panasonic spares are supplied by Statewide Appliance Spares or JNG. Get the correct part number from the service manual.

Yes Ld board, what on the board I don't know.
I wish at time like this I finished my traineeship when I got out of school.
I had the fets off the board and they seem to test OK, so I will try find out a price on a new LD board and see if it's worth the money to fix. It was a free TV, so easy come easy go

What's the chances of the LD board from a tx-l50b6b
Working in this TV?
See attached manual
The P board and LD board schematics look to be the same
And I can get the board cheep from the UK
