Dear Coppell TV Repair,
just got a Vizio P42hdtv10a in, it has a bad ysus board I
think, how do I test for shorts?
This post comes at least 4 years before it should have been posted, but then again if emails keep arriving asking about it I guess it is not too late either.
Vizio P42HDTV10A is based on the same plasma display technology by LG (read: plasma display, sustain and buffer boards and main plasma logic controller which orchestrates them) as many , many other TVs from many, many other vendors.
There is a known culprit in the two sustain boards , which are practically wearable and certain to fail after so many hours of use.
To find out more just refer to a related post I've made a few years ago about troubleshooting HP PL4260N:
