BC109:
This is the HD panel.
It has no picture or sound. LED goes from RED to Green then back to RED(Stby), thats it.
YSUS & ZSUS have been remove from power with same result. There is no main voltages Vs etc, even with green LED.
Would this be a power supply problem or can control PCB cause this?

tv tony:
monitor pin2 on plug 801 on the psu, when the relay kicks in should be approx 3.4 v. if this disappears when the set shuts down u have a control prob. usual cause is the two silver connectors on the two signal pcb's
do you want service manual?

regards tony walker

norman:
Hi, Sorry to hijack your thread, I need a Y sus board for my own tv, part number 6871QYH051P. Can you help Tony, a second hand board or even new one depending on price would be good. Thanks Norman

BC109:
Thanks Tony.
I have a manual but it lacks in the power supply department. I seem to find Plasma manuals aren't complete & guess work is needed for the rest.

Norman, here in Australia they sell new for ~$270 AU + postage. Not to bad.
YSUS seems to be a common fault with these panels.

tv tony:
hello again norman, 6871qyh051p no longer available, replace with 6871qyh042, i dont know if this is suitable for you depends on control pcb fitted, get ready for price...£168.00, ouch!
