Newbie to this and have been doing alot of reading.
Have the above named PDP42G1 panel which is not showing any picture.
Check the Va and VS and they are correct from the power supply board.
When the unit starts up the YSUS and ZSUS boards sound like they are "priming" as in they humm, quiet loudly actaully.
Nothing on the screen and nothing when shining a light on it. ZSUS is feed from the YSUS board.
Checked the VSETUP/-VG as labelled on the board and it looks as if there is something wrong there, but i dont know what the expected values are:
On the panel it has:
-187/140/NA/100
but im not sure which values correspond to which. My readings are:
VZ=81v
VSC=2.1v
-VG=nothing
Should I be looking at the YSUS board or maybe the controller board not giving the signals to prime the YSUS --> ZSUS up properly??
Any help appreciated.
Thanks
