JVC 32 " T.V. dead.

[Dani]

JVC Model # AV-36980 Chassis # A 70, was at another shop, but in good
condition.
Found the SMPS STRF6626 regulator shorted, replaced it, & C926 1000 uf
@ 50 volt
capacitor, everything else checked fine, plug in, & at turn on,
instantly, the fuse blows
.....flash, regulator gone again. Didn't even try to start. Anything
common on this unit?
Thanks, Dani.

Checked everything (diodes, resistors, etc). STRF-6626 has lot of
self-protection built in but one thing this IC can't protect against
is bad damping circuit, any shorted diodes in outputs and bad
transformer.
