Hi,
I have an RCA TV model 27F520T, ch M134C (mfg 06/05) in my shop that won't turn on. Note: I do not have a schematic.
I replaced IC801, STRW6735 in the SMPS. When I plug in the AC power cord, with a meter connected to the regulated B+, the voltage goes over +150V then slowly drops to 0V. I suspect the reason is due to too much voltage. It is possible there is a problem in the feedback circuit, but I do not have a schematic.
Did you have a case like this and what was the cause?
Note: A service manual is expensive and "justmanuals.com" and "diagram.com.ua" doesn't have the SM.
Do you know of any other web sites that sell SMs at a reasonable price?
Thanks in advance, Brad
