Here you go..........
The only way to prevent this is with a UPS unit that keeps the TV running, and gives you a chance to do a normal shutdown with the fan running.
I use an APC Backup UPS 1500 to power all of my gear, and it protects much better from surges and shutdowns that a cheap "surge protector", which is worthless IMO.
In 20 years, I have never had ANY electronic gear fail. I think most of the failures and problems people are always having with their TVs and receivers etc.are due to power surges.
I think a good UPS unit is a wise investment of $200 or so. It seems to keep all of my electronic gear out of the repair shop.
It will use about 30 watts for 5-10 minutes after turnoff (the lamp cooling fan is running), and then it only uses 1 watt after that in standby.
Those are measurements done with a 2% accurate Fluke AC power meter.
If you have a power outage, the fan will not run and the lamp will be damaged by excessive heat. This drastically shortens the lamp life, which is normally 3-4 years.
You should always have a projection TV plugged into a power backup unit that keeps the TV temporarily on and the fan running after TV shutdown.
Replacement lamps that you can now buy for under $50 are identical to the ones sold with the Mitsubishi name on them; same lamp manufacturer.
I'm new here and had a question about a 92" Mitsubishi with some shadows or marks that show up on the screen. I posted my question on a 92" Thread but does not look like it has much activity.
If you don't mind weighing in on it I'd really appreciate it.

Sounds like the speakers are set to OFF for using an AV receiver. Download the owners manual and it will tell you how to turn the speakers back on
