Subject: [TechAssist] PANASONIC TV MODEL CT32G11U REGULATION TROUBLE
Hello everyone I am working on a Panasonic tv, It came in with a blown fuse
checked all components in
power supply and hv found no shorts so replaced the fuse and as soon as I
pluged it in the hot shorted
unsoldered the collector and measured the voltage it is running at about 360
volts. went back to regulator
found an open .22 ohm resistor also two blown electrolytics on in the collector
of the hot and the other
in the regulator. replace the damaged caps replaced the regulator stk730-020
and still running about 360
volts all voltages on the regulator seem close except for pin four which is
supposed to be -.4volts it
measures +15volts I have checked the resistors and filters in the circuit and
can't seem to put my finger
on the trouble any Ideas would be appreciated greatly
thanks
