My rca 52 inch hdtv turns itself off after a few minutes
We turn the tv on and then within a few minutes, it is back off, we have had 2 services guys come out and try to fix it, and this has cost us 300.00 so far, the tv is just over 1 year old, I bought Rca because of the name, now I am extremely dissatisfied, I expected it to last a little bit longer for the price I paid, Now the image goes to a green and then off, sometimes we just get sound for a few minutes. Can anyone help me.

It has you Posted as a projection TV and Not DLP, if Fan to Lamp stops running set will shut off to protect Lamp,I had a DLP that would play sometimes 30 mins then shut off drove me crazy trying to firgure it out and it turn out to be Fan would stop running I replaced Fan TV working fine . When you remove back engage toggler switch to up position put a piece of tape on it to hold it is a safty switch ,then turn tv on watch to see if all fans are running also if when tv trys to come on is there a spark coming from Ballast Board if so your new Lamp is defective it does happen if not your ballast board maybe Bad it is what turns on Lamp.If all fans are running Ballast Board.
Your TV is overheating.. easiest remedy is to point a fan at the back of the TV or... clean the inside of the TV, Im sure its full of dust and stuff... this prevents air circulation inside the TV thus creating more heat...
My RCA 52 inch was doing the same thing. TV guy had me use a regular hair blower blowing very hot on the power supply board ( bottom left in back). After a few minutes the tv would come on. He replaced 2 capacitors, charged me $100.00, plus the $95.00 service call, and is working fine now. This was a month ago. So far so good. He only took the board to the shop, not the entire tv. Hope this helps.
yes it could ba the cable itself even, but i suspect more the tuner circuit or tuner itself may have bad solder connections. Here is another test for you to try, plug another dvd or vcr, or xbox etc. into the back, using one odf the inputs. See if this works like the built in dvd. if so it will be more likely bad connections in the tuner or surrounding circuit.
