pioneer avh 6300bt is turning on and off

[beau123]

since a few days i have problems with my flip-out radio.

when it is turned on and suddenly it shuts itself off and it goes back on.

multiple times sometimes, i have tried anything from using another radio, tried it in another car.

only the cable for power so no speakers antenna's rca's of remote connected and still it shuts itself off.

does anybody knows the problem?

its also warm when it shut itself off.

if i can't fix it i need to send it back to pioneer.
