    Panasonic SC/YSUS Board diagnostic

    Hi guys,

    I have recently gotten a plasma TV with a shorted SC board. Someone had been working on this before i got the set. Solder work can be seen in some of the mosfets, a gate driver and a couple of other components, so I'm not going to be replacing things until I know where the problem lies. Whoever worked on it before left a pretty bad job behind.

    I coulndt find a technical information online explaining what exactly is the SC/YSUS board function. A similar question placed earlier on this forum Y Sustain Board pointed to an external link, but that is only for troubleshooting, it doesnt explain what the thing function is.

    This appears to be some sort a switch mode converter to power the buffers. If this is the case, I could remove the IGBT's, plug in an external supply for the HV output to the buffers and see how the drive circuit is working to continue my repair. What sorts of voltages should I be looking to see at the output? Thanks
Working...
