Tv Turns itself on

After turning off the satellite dish and the TV for the night, we woke up and the tv was on. It was showing the dish screensaver. I now have to pull the plug, because it happens everytime we turn the tv off. Any advise would be appreciated, Thank you

Your RCA TV has problems. You did not specify the model of TV. I will tell you, most of the RCA sets that will come on and shut down are nightmares for us TV repair people. The best solution is to replace this TV. I have had real headaches with RCAs that have your problem. Even if you have it repaired....its only a matter of days when it will continue to shut down.This is very good advice, though sorry to hear your TV is on the fritz. Thanks for asking and show all hands of support!

My tv will turn on and then after a while it turns itself off and then back on in a few seconds and this repeats all night

there is most likely a bad connection on the power board. i really suggest not letting it do that all night unplug the tv it can do alot of damage to the tv if it cycles like that for long periods of time.

I have a Toshiba 46H84. We had a lightening storm one night and the next morning the satellite dish and TV were turned off. DVD player was not and worked fine. The satellite dish needed to be reset, but...

Yes, all sets are protected by a fuse where the power cord enters.

Start at the beginning--unplug the set and look for the glass fuse--should be a 5 amp or greater. It will be in a plug in holder. If you are lucky the strike or power outage got it.

Do this with the set unplugged.

Let me know what you find---I am here to help.

Total loss of power to the set indicates either the ac fuse is blown or the the power supply is damaged.

Unless a tech actually opened the set and looked at it he is just throwing darts at the board.

I am here to help--if my suggestion informed you rate this solution as "very helpful" as I do this here for free.
