Hi there,
vestel 11ak30 tv.
here's the story so far...set had a shorted HOT (would not come out of
standby, if keys pressed set just chirped and red led stayed on). Set
powered up fine without HOT in place. Connecting bulb across c-e showed
b+ OK. No obvious solder problems, just resoldered one or two slightly
suspect joints.
Now for the annoying bit: Replaced BU808DFI HOT and c618 (according to
schematic,7n2). New transistor blows out immediately. Now suspecting
LOPTX shorted internally, before I replace it though, has anyone seen
this problem before on this chassis?
best regards,
Ben
