PN60E550D1FXZA, No PS_ON, only joystick "beeps",

[Paul678]

And the picture is completely black.

Again, no PS_ON signal at all, so only like +10V on Vs, which
should be around +215V, I believe.

There is a single control joystick, and I can get some
menu "beeps", but that's about it.

I found this online:



But it looks like I need some sort of test jig to do the logic board test patterns?

Disconnecting the X-drive cable from the SMPS didn't change anything.

I think it could be a problem with the main board, because the
+15V and +5.3V are present, and the +5V Standby is there, just no PS_ON.

Any ideas?

THANKS IN ADVANCE.....

Did you try Y-main isolation as well?

Yes, because Y-main is fed by X-main in this case.

But Good to see you are still here, Tom!

Hope all is well with you!!!! Haha!
