No Power in my RCA TV.
There was a humming sound and then it just switched off and will not start again.
TV Technician told me that it was due to shorting out of Power supply which is a very usual feature of RCA TVs

When the color wheel starts to go there is a high pitched whinning sound, the humming could be from the light engine or ballast, which may or may not be related to the color wheel. I would have to see it and test things for a correct diagnoses, but it does at least sound like a color wheel in the last moments of its life
Its not the starter thing, there is a problem on your HDTV power supply section, a problem or symptom like what you said is a component malfunction. Any component that becomes defective most on the part on the power supply system will only bring your HDTV on standby mode and nothing more. A qualified service technician could repair such problem. Over doing it and take chances that your HDTV will gonna work would bring more problem. So, call your electronic service technician or bring it to your nearest service center.
i would open it up and first locate the very large filter capacitors in the power supply they look like little cans of soda. its value is anywhere from 22,000uf to 400uf.
the old color wheel on models pre 06 have bearings. The new replacement dosn't. The noise you here is the bad bearing. Mine got so loud I couldn't take it anymore. Just replace and noise is gone! I did mine myself. Not that hard.
oVERSEA'S ...thats just wrong... rca parts are availble all over the place. does the sound eminate from the speakers? DOES it go away when you turn it down.. if so two possible outcomes. speakers or something called ssb board which is the main signal or main board in this set. but the audio amp and all audio cuircits are on this board. this board is however technician replaceable only.. authorized technicians have a special computer interface used to transfer settings from old to new board. there are cases where if the humming is coming from the back which might mean flyback or a coil vibrating. is it a lound hum or whine? o buy the way i get most of my rca parts at the shop from union electronics.
I think that both of you have faults on the power supply of the tv. If you are able to check this yourself start with the diodes and resistors if not then find a competant technician. Hope this helps.
