Default Sony Kp51WS500 really stuck

*.

There is a bad picofuse on the power supply board. I previously mentioned
this possibility in addition to the fuses under the heat sinks.

quote:

"There are some Sony models which get a bad picofuse on a separate power
supply board when the convergence amps fail, in addition to the picofuses
hiding under the STK's heat sinks"


Mark:

I agree from my reading of extensive discussion at the TECHLORE.com
site. Therer apparently are two (2) PICO Fuses on the G Board that
you haver to check also.

Several indepth articles and discussions on the OSNY convergence
problem, these STK you reference , etc. there. It's a plu, for sure,
but only because it's the best info site on these issues I've found.

I'm repairing my SONY KP-61XBR38 convergence issues now. My set uses
different boards and ICs so it's not as cookie cutter.

Also, the moderators from that site have their own REPAIR KIT website
(tvrepairkits.com) where they bundle all the typical parts, paste, and
INSTRUCTIONS into a kit for hobbyist use.

Hope this helps.
