TV shuts itself off after a few minutes. Will also shut itself off if the DVD open/close button is pushed. Not sure if a DVD is in the machine or not. Any ideas??

Make sure the top and back of it are not dirty or obstructed, it sounds like it is overheating and shutting down to protect itself. Or your main power board is going out.

sometimes they need to be pushed that little bit further in and make sure the eject button or open button is not stuck in .
hope this helps.

The door drive motor may be frozen.

1. Shut down the computer and unplug it.
   
2. Open the computer casing to access the DVD drive from inside.
3. Disconnect the cable on the DVD drive leaving only the power supply connected to it.
4. Turn on the computer.
5. Push the OPEN/CLOSE button on the DVD drive. If it does not open, the drive is broken or the door drive motor is defective. If it opens, push the button repeatedly to open and close the door repeatedly to release any frozen part.
6. If the door does not stuck anymore, shut down the computer.
7. Reconnect the cable and turn on the computer.
   

push down the button to open the lid, keep it pressed down. right next to it it a tiny button that detects whether the lid is shut. tape a little piece of folded paper onto it and then it thinks the lid is always shut. it just means you have to switch it off to remove the CD

The drawer seems to hang up when it sits closed for a while. I found that using a very thin but rigid metal item such as a nail file under the leading edge, allows it to open with the first press of the  open/close button. I load the DVD, press the open/close button and it closes and stays shut.  After I submitted my problem, it occured to me that the reason for the door to continue to open and  close, was the repeated pressing of the button. The door was merely responding to each time it was "called."

I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

The DVD drives go bad on those constantly. Getting a replacement should fix your issue. It's a very simple process to install that. There are 6 T15 screws on the bottom of the XBOX and 3 T10's holding the dvd drive in. Replacements are $20-30 on ebay.

I have the dv9000z. If I do NOT push the DVD drive tray all the way in until it CLICKS shut, then it OPENS again after 1-2 seconds. This is normal. I have found that most times when I close the DVD tray drive, I am not pushing it in far enough, because the top of the DVD tray is rubbing against the laptop's case. If I just press down VERY SLIGHTLY and push the DVD tray in, the tray will fully close and CLICK shut. This works for me. Good luck.
