Replaced the color wheel and put it back together and the lamp light flashes. The lamp doesn't come on the 3 fans are running. It will try this a coulple of times then all 3 leds will flash. I checked connections and can't find any extra. I was successful in breaking the cover interlock and need to know if the closed position is an open or a short.

Loud sound you are hearing is coming from your color wheel and has your Lamp ever been replaced? this set has 3 Fans they all must be running for set to operate correctly! Encompass Parts has Boards and Color Wheel But for Lamps Mats has them for 99.00 1-800-628-1118 and EC Parts 1-800-638-3328
With the back off of the set it will shut off. There is a lever it engages to prevent the set being operated with the back off.
The color Wheel will cause a fan like or high pitched grinding noise. I can tell you where to buy it and also there are on the internet places with written and VIDEO instructions for the replacement in most of these sets.
Put the back on and see if the set again works and still has the noise.

Regarding the tv turning, my question is, do you hear a clicking sound? if so, it's most probable tio be your ballast, that might not have enough voltage to keep on with your lamp, and that's why it shuts off.
You could try replacing it and seeing if it resolves your issue, I believe they're running around 70 dlls..
have a great one ! :)
That's probably the Color Wheel you are hearing. When you turn the set on the color wheel has to run, one of the several things that has to happen for the set to come on. The color wheel sends a signal back to the control circuit to tell it it's running. If these sets fail to light the lamp they will shut off and try again, that's why you hear the color wheel start then wind down then start again. The set should try three times before it decides it's not going to be able to turn on.
One way you can tell the difference in the fan sound and color wheel sound is if you can get the set on, let it run for a little while so it gets warm, then when you turn it off the color wheel will start winding down but the fans will continue to run for a minute or two.
Make sure that you have the orange flat cable turned the right way when you plugged it in. I accidentally turned one the wrong way and that was the response I got. Hope this is all it was if this does not fix it I would measure the ballast and make sure the 200 or so volts is coming across.
If your having the "3 light" problem it could be an indication of a bad lamp however if there is a buzzing or a grinding sound it could be one of two moving parts. The color wheel or the cooling fan. I would go the cheaper route and replace the color wheel first. The thing is the lamp will not turn on if there is a problem with one of the other two parts. TRUST me ... I've replaced all three parts just to find out it was only the cooling fan. (at least I have another lamp handy when the new one goes out). The motor on the cooling fan is too small for such a big fan so I would definately try it first. It's a big problem with the DLP tvs. Hope this helps.
