I have a Albatron LNX-21TIS-3 lcd tv. It does not power at all. (bad power supply?)
Cant find any local repair shop familiar with that brnd. Also the website http://www.albatronusa.com/ has email fax and (you have to look for it hard) phone number but fax is always busy, phone says line is disconnected and email does not get answered. help!!!
I just fixed my Albatron LNX-21TIS-3.
The power supply had gone out so I took an ATX computer power supply and changed the plug.
The Albatron runs on 12V and 5V just like the ATX computers. The trick is to find a power supply that is the same size then you just modify the wires on the power plugs to match up.

How old is the RCA TV. Is it an LCD Projection model or the older CRT (3 tubes - Green, Red and Blue) type projection model?
If LCD it could be a bad lamp or power supply. If a CRT it could be one of the Tubes is bad or again a bad power supply.
That problem is usually cause of faulty capacitors on the power supply board..
Just follow this instruction to fix your TV..
1. Open the back cover of your TV. 2. Look at the power supply board..Its normally connected to the power cord.. 3.
After that,,try to look at the actual image of capacitors if it is
bulged on the top so that you can easily determine the bad capacitors.. 4.
After that,,try to replaced the bad capacitors using soldering iron and
soldering lead..replaced the capacitors only with the same type ratings
and value.. 5. Some of the capacitors not bulged so its better if have a capacitance meter
You may have power supply problem due to bad caps, open it up and look at the power supply module for bulging top or leaking. To have it repair will more likely to be over $100 plus parts if you can find the shop to repair them.

Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc. http://en.wikipedia.org/wiki/Capacitor_plague Please post back what you find. If the tech installed a used power supply, it may be bad also. 3 years are typical for capacitors to go bad.
Is it a rear projection set? or LCD? If it is a projection set it could be a bad High voltage splitter. Part is about $30 If it is LCD it could be a bad power supply or inverter board. A good tech can replace capacitors in power supply without replacing the board
