Turn on tv, no sound or picture a few seconds later it begins to hum as if it is attempting to start up only humming is louder than usual. The blue light begins to flash and the tv will try to start again, but will not.

AKAI 54" Big screen, Turn TV on picture no sound, then within a few minutes humming sound gets louder then stops and starts

Sounds like the audio amplifier circuit is bad. I do not know if where that is in that TV. If you were to hook a boom box or stereo receiver to the TV (via the audio out jacks on the TV), you could monitor the sound that way. If you get clean sound, then the problem is in the amplification circuitry. If you still get humming, etc., then the problem is further upstream.

Also, clarifying... the picture has not changed one iota, correct?

Its the color wheel assy. Its changing speed due to worn bearings. You may also hear a hum coming from the rear of the TV. Seek an RCA authorized service center to resolve this.

This is a terrible thing to tell you, but, what you describe is called dijitizing then the light engine failed Now it gets real bad ,,, This part 261589 is about $590.00 and is on factory backorder with no ETA in site. We have been waiting for one of these at our shop now for over 5 months. RCA knows about this problem and you might want to give them a call and see if they will do anything

Loud hum when attempting to turn on my RCA F27628 27"TV

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
