samsung ps-50c96hd

[thuss]

Hi

My tv was just clicking and I have changed the mosfets on the psu and now the the tv comes on but no picture. I know I have to replace the y sus and buffers boards but before I do I need to get the psu working properly.

The problem that I have got is that I am getting 0 volts on the pin (vs-jp)next to the y sus connection block, I was wondering if someone could suggest where I should look in order to repair the psu and restore the voltage to the y sus?

I am getting 64v on the pin A-TP.

Thanks in advance

Try it without the Y sustain connected.

I have tried it with the Y sus disconnected but still get no voltage....I thought that the pin would still give 200v regardless of whether it was connected or not?

Does the X sustain connect thru the Y sustain on this model? Pictures would help...

Here is an SM which may be a close match.

No the x sus does not run through ysus. Please see page 4-2 , service manual ps-50q91h. BTW thanks for the manuals
