I recently bought this set and it has a great picture, but every time I turn it off, the lamp indicator blinks for a few seconds. I don't have a manual yet and wonder if this is normal or it has a bad bulb. Any answer would be greatly appreciated. Thanks.

The lamp runs so hot that there must be a cool down period after the TV is turned off, otherwise the residual heat would cause the lamp to burn itself up prematurely. The blinking time after turnoff is indicating this cool off period.

I concur.

My set does the same thing. Usually after it's been on a few hours.

Turning these lamps on and off needlessly is not a good idea since it will greatly foreshorten their lives, so Mitsubishi has engineered in some protection.
When you turn your set off, the screen goes dark, but the lamp actually stays on for about 30 seconds. It does this in case you accidentally turned the set off and want it back on; you have 30 seconds to do this without consequence. After 30 seconds, the bulb turns off, but the fan continues working for cool down. This is the time when you get the flashing green light; the TV must not be turned on and is interlocked out for about 30 seconds. The cooling fan then turns off, the light stops flashing, and from then on it is OK to turn the TV on.
This process is fully automatic and has nothing to do with lamp temperature . Lamp overtemp triggers a flashing amber lamp.

I have an RCA DLP that does this also but has a blue screen so you know it is still within the time to turn it back on. I usually get close to 7,500 hours on my lamps as we do not turn it off unless we are done watching for more than 1/2 hour. It is getting less use now that it is in the kids' TV/play room, and no longer the main display in our house.

I have the Mitsubishi WD-65733 and I just replaced the DLP chip and I have a clear picture but now when I turn the TV on it plays for a while and then the lamp light starts flashing and the screen goes dark. The lamp has not blown because when I unplug the tv and plug it back in it comes back on and repeats the same thing. Does anyone have any suggestions?
