I have tried all suggestions with no result. Replaced diodes
transformer,caps and resistors pretty much turned into a shotgun job and
still won't go.
TV will intermittently go to a noticeable buzz (in stand by) from switch
mode transformer and output B+ (voltage 205V) and will not work. After a
few false starts it will eat the STK again. We are beginning to replace all
the parts in primary and secondary power for the 2nd time. Thanks for any
input.

> Hi All,
> This RCA 35" F35673MB, CTC 187CL3 was repaired 2 months ago with STK
730-30 bad and CR 4106 shorted. Replaced with OEM parts from RCA.
> Unit is back and intermittently will kill the STK 730-30 again while in
standby mode. Have been able to get no handle on cause. In standby the
voltage out goes to 207 volts and pin 1-2 go to 0 and it dies. May turn on
and run normally 9 or 10 times in a row then it won't start just squeels and
dies. The earlier post lists a parts list we have tried. Maybe just bad
regulators?? Trying another source. Anyone else seen this before?
Suggestions?
