Philips dvp3140 opening and closing all by itself

LETS SEE , check out first your REMOTE CONTROL , it could be that some buttons are stuck sending signals . this is how your going to check : lay down your remote and using a digital camera , point it to the EYE of the REMOTE , now look at the screen of your digital camera , if you see the EYE of the remote BLINKING !! thats your problem there. hope its works.
