Loud hum when attempting to turn on my RCA F27628 27"TV
TV has been slow to turn on during the last few weeks. Occasionally will turn itself off. Tried to turn it on and a fairly loud hum (not sure of loaction), then a pop. The picture or sound did not come on.

Could be that the main b+ filter Capacitor went bad and blew up. Also could have been the horizontal output transistor shorted and the flyback poped. In eather case it would be recommended that you take this set into a repair shop unless your familar with HV circuits in tv sets. Good Luck

I just want to ask you something before I give the solution, does the unit gone to start-up problem (needs warm-up before it finally turn on, needs to pressed the power button key several times, needs to unplug from the outlet and plug it back in)before, you have said that you've encountered it last few months?
If it is a ctc or ptk 195 then you have a bad flyback High Voltage transformer: the large white kindof square thing with big red wire coming out; Must get original RCA part. If picture was good before could cost you a total of (average) $300.00 according to which repairman.
