My RCA television shuts itself off and then it comes back on without anyone touching the remote or on-off switch. I unplugged it, hoping to "reboot" its brain, and thinking it might have just overheated. No change when I plugged it in again.
I have a TIVO attached, but there seems to be no difference when the TIVO is not attached, so I don't think that is relevant.
This is a reasonably new TV.
Thanks for any help. No one repairs TVs in my town. Since when did they become targeted for annual disposal?
After an inquiry on the RCA website, RCA sent me a 1-800 number. A "resolution specialist" went through a series of questions with me and determined that RCA would replace my TV after receiving a FAX copy of my original bill of sale. It is on its way now. RCA did not offer to pay for repairs but opted to replace the whole TV. Number is 1-800-336-1900.

Try unplugging it from the outlet for a 5 minutes, and try again. If that doesn't work - try plugging in a lamp to the outlet to make sure it works. You can also try connecting the TV to a different outlet (check fuses or circuit breakers). If you use a remote - change the batteries - or try using the power switch on the TV itself.
If it doesnt work - provide the brand and model of your TV.
If the set comes on by itself it may be a problem with the power switch on the front of the set; lots of these sets had problems there, the only way to know is remove the back cover and locate the cables that come from the front keyboard and unplug them, the set will still work with a remote.
I can tell you exactly where to look for the plug. If unplugging it cures the problem you have two choices: either just use the remote or remove the front keyboard and repair/replace the power micro switch.
Let me know as much as you can so I can assist you.
If you leave the tv unplugged for 2 days (atleast) then plug it back in and try to turn it on and if it comes on its the power supply board. If it comes back on it will probably shut off between 30min to 4hrs and you would have to unplug it for 2 days again. All the power needs to drain out of the tv. If thats the case take the back pannel off and check the part number out on the internet. Not hard to do becarefull touching things the power supply does store a little bit or shock in it. Good Luck.
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.
You don't need the remote to unlock the TV. Any RCA universal remote will change channels etc if you want a remote. Now from the manual: simultaneously hold down the menu/OK button and the Volume down button for 3 seconds. This resets the pasword and unlocks the TV. You can then enter the menus as usualI believe to control/clear parental settings etc.
The menu button on the TV itself is bad and must be replaced ( or removed ). Alternatively the whole front button assembly can be disconnected. Just follow the wire back to the main chassis and unplug it.
Sounds like trouble in the standby/power up circuit. have you tried unplugging the TV for a half hour and seeing what happens? It might start up but I think this problem won't go away. If you heard a high pitched buzzing it sounds like a problem in the high voltage not letting the start up circuit work. threy are related. The start up circuit waits for the high voltage to stablize and then switches it on.
