If it is a projection screen you have to take it apart. First lay the tv face down on a bed then remove the screws that hold the back on. Be carefule some of the screws are hidden and most of them are torx bit. Please make sure you dont void any waranty by doing this! When you have all the screws out the flip it back over and carefully pull the face and screen off. This will allow you to clean it. DO NOT use anything but mild soap and water. I hope this helped.

one of two basic things here, unplug set to see if after a while it helps, and if channel scanning up or down on its own suspect the button associated with the direction it changes is a bad one.

Just make sure that the wall outlet you are using is actually live. Try plugging in a reading lamp to that socket to make sure it has power.

If power is good, then check where the power cord enters the back of the tv for a fuse holder.

If there is one there, then unplug the tv and replace the fuse with a new one.

Otherwise you might be looking at getting out your screwdriver and disassembling the tv to have a look at the main power supply circuit board.

I looked at the owner's manual located at the following link but they did not mention if the set had an easily accessible fuse there or not.


Good luck and keep us posted on how you are making out.

This is a crazy set, I have the same one, and Dell does not support it, and most electronic places don't either You problem is the audio(sound) board, this has an IC on it that can't be found, I once found the board on ebay, but did not buy. Good Luck!

Well I couldn't find one in my collection either. However if you can upload a high res image of the lock to imageshack.us and get me the link then I can tell you how to remove it. Also what are you trying to remove? Is it the back cover?
