If the red light won't come on it is not getting power.First,try plugging it in to a different outlet,or unplug one of the gadgets you know is working and plug the tv in there.You are simply switching.If you know that there is power coming from the outlet and it still won't come on then you'll have to check the cord;don't go much farther than that without expert help.
does the power light flash three times slowly then stay off? If so chances are its just the CP150, cp120 and CP114 capacitors. There is the RCA repair kit by that same name available from www.tvrepairworld.com which has the capacitors and the CD with repair instructions
Some of these sets if you unplug them---The green power light will blink for about 70 seconds before it stops--this is normal as the receiver unit in this set is booting up. Wait for the light to stop blinking and then the set should turn on. Some of these sets develop a problem where the light never stops blinking--usually the receiver is now bad--very expensive to get fixed.

Check the "Sleep Timer" settings. If set to 45 minutes then TV would automatically turn itself off 45 minutes from being turned on. The variance in the "on" times is due to the TV turning itself off after not getting a signal from the remote for fifteen minutes.
