My RCA unit has developed a problem where the tv just comes on by itself after a few hours of sitting idle. The problem started when I was on vacation and we returned to find the unit on. I dismissed the problem until the unit kept coming on during the night and through the next day. I now have to unplug the unit to get any sleep. This is unusual? any ideas?

More often then not a decoder board would be your issue here. the decoder board or AKA tuner/decoder puts the signals on your lcd display. When they give up on doing that you get these nice stripes on your lcd display. Now if it where the screen itself you would have "dead pixels" or stuck pixels , witch is not the case here.
What you need to do is ether bring it to a TV repair shop or try and get the part and do it yourself. What we are talking here is do it yourself. If you not into that then your going to need a repair shop its going to cost about 2 3rds or more of what the tv is worth to fix, So this is where you might want to consider your options.

I would buy a replacement power supply unit from shopjimmy.com http://www.shopjimmy.com/rca-cef273a-power-supply-unit-no-wire.htm That should take care of the issue. I have seen some that will have a backlight inverter problem and so you could replace them both and you should be ok.
it will either be a defective tact switch on the control buttons on the set or a main board causing this problem it it still has warranty you would contact RCA and get the number of a local servicer to assist you with this problem
I had a similar problem with my Phillips 42 in. LCD HD TV.
Here's the problem. The Power Supply Board. I opened my TV
up(warranty was up of course) and found several bad capacitors.
Phillips and several other companies were sold capacitors that although
were highly rated failed within 5 years because of a lack of
preservatives. All sorts of electronic equipment is now being effected
due to these defective capacitors.
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.
