REQ: Technical Info on Arcade Monitor

[Wes.]

Toshiba 50" Rear Projector Engine Model No-R502L
PCBs
VIDEO/CONV PB6101
HOT/FLY PB6105
CONV-OUT PB6112-1
POWER PB6106

Looking for any Service information on this monitor, Google search has
turned up zip. Does anyone recognise any of the Toshiba PCB numbers?

Regards
Wes.

PS. No faulty units as yet just would like to have any info on file when
time comes.
