Pioneer PDP-433MXE Power Supply fault
I am attempting to repair the Power Supply Unit ( board number PCB2310
A06-12196B MDK79V-0) fitted to a Pioneer plasma panel PDP-433MXE (similar to a PDP-503MXE). I have found most of the faulty components, caused by the failure of Q127, and its source resistor, but I don't know what caused Q127 to fail in the first place. I have traced out part of the circuit (schematic) and have tested all of the likely items. I am unable to find a service manual on the web which contains a circuit diagram, but I have found some references to this fault on a Russian website, only problem is I don't read Russian ! Even so this has been usefull in identifying some of the failed components. Does anyone out there have a circuit / schematic for the power supply which I can have, or does anyone know what causes this fault? Any help would be most appreciated. Thanks. Ian. |

Did you find all the fixes to bring this plasma back to life? My PDP-433MXE just went pop when I tried to bring it out of standby |
