Rca rt2911 will not come on at all - Televison & Video

If this is actually 20 minutes each time, then you could have an auto power off option applied.
If it switches off at a random time after say 20 minutes, then it could be caused by a overheating problem. If the System has a fan make certain it has room to operate, that nothing is blocking it. Also check all speakers and cables for faults.
If the device is overheating you should be able to feel it!

se que maron las salidas

look for a button on the remote that says input select or something like that. Should be able to switch between input options.

Try with an hdmi cable . I think

Try another tv set

Did you try reversing the speaker cables in the back of the unit? I mean making sure the ground wire ( the wire with a black stripe on it ) is in the right connector.
