Hi,
I am trying to find a circuit for the Y SUS board used in the Toshiba 50HP16, its not in Tosh's service manual as its made by LG and I expect that tosh just buy them in with the LG panel. I am sure it is used in most plasma's with the 50X3 panel. If someone knows of a service manual that has a circuit. please let me know. The LG Part number on the PCB is 6871QYH039A.

TIA,
Richard.

75003042 is Toshiba's part # for the Y sustain board. Are you trying to trouble shoot it?

Hi,
Yeah, I have two faulty boards which I need to repair. But I am having difficulty finding a circuit diagram for this PCB.

Regards,
Richard.

Manufactory’s warranty? Replace the X and Y sustain and power supply. Is the fuse blown on the sustain board? Or is this an out of warranty fix?

These are board level repairs as far as Toshiba is concerned. If you have two bad sustain boards I point at the pdp. "Panel"

Hi,
These are out of warranty repairs, the PDP,s are fine as I have tested them with working cards, one the cards seems to have a short circuit in the energy recovery circuit and the other one only has the negitive half of the Y drive waveform no + 193v. All I need is the circuit diagram so I can fault find the boards.

Regards,
Richard.

I pulled the schematic and Toshiba does not supply a way to trouble shoot the sustain boards to component level. Back to square one. Board replacement. You can call Toshiba and see if PTS can repair these boards. That's about it.

Hi,
Do you have a Toshiba part number for the CTRL board. LG part # 6870QCC013A or 6871QCH059B?

Thanks in advance,
Joe

Does anyone know where to get one of the Toshiba #75003042 for the y sustain board? It is on back order from Toshiba and they have no idea when they will arrive.
