Hi Charles,
Sorry for the late reply, I'm offline upon purchasing my service.
You have said that you can hear a low buzzing sound before the unit gone to subsequent shutdown and the lamp blinks green(meaning that the unit try to turn on the lamp for consecutive attempts but not generally mean that the lamp itself is faulty.) and the temp led light come on.
As a matter of fact all the information you have mentioned linked to the symptoms you've encountered right now. A low buzzing sound might be caused by faulty FAN inside the unit that trigger the error code (blinking of the standby/temp led light) and turns off the unit automatically due to thermal protection circuit.
However, the technician might be true also that the buzzing sound came from the faulty color wheel. To confirm it, you have to verify where the buzzing sound came from. Color wheel is in front of the lamp assembly. Faulty color wheel can produce the same symptoms you've encountered right now but most of the time, it shows 3 blinking led light at the front panel (Timer, Lamp, standby/Temp).
I would advice you to open the back cover of your unit, fixed the lamp door safety switch with the tape to make it in closed position( if it is on open position the unit will not power up), and then turn on the unit and observe the fans if will spin or not, and check also where the buzzing sound came from before the unit gone to shutdown.
I've suspected that the fault came from the fan based on the led light flashes. Please let me know what you will discover after following the steps above to verify where the exact fault came from. Also, let me know the exact status of the led light at the front panel, (Timer, Lamp, standby/Temp ), which of them lit solid/blinking, it will help us to narrow the caused of the symptoms.

I taped the lamp door cover spring down pluged the TV into the electric outlet I heard a click the TV went on after a few minutes the picture picture was OK for about 15 minutes then it got darker and the colors ran into each other for poor picture Quality also the only way I can turn the TV off is to pull out the plug from the outlet & to turn it on plug it back in the on & off button does work. any suggestions.
The symptoms you've mentioned right now is an indication of faulty DMD board. If this board gone to malfunction, symptoms below will be encountered.
- Poor picture quality, vertical lines on the picture, grainy pictures, abnormal color and other picture problem.
- Video lock up either immediate or intermittent.
- Sound OK, but no video and/or control funtions.
- Unable to turn the unit off, or no control of functions. The unit needs to unplugged and plug back in to power up again.
- Control to color wheel is not normal resulting to abnormal colors/picture and performance of the color wheel.
You need to replaced the DMD board (part no. BP96-00678A)
