If you have a power interruption, the cooling fan will not run and the lamp will be damaged by excessive heat.

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 230 watts when on.

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.

Hi, 

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.

Bypass the Mitsubishi sound by using a soundbar or receiver and speakers instead.

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

i never turn off the power till it's been off 15-30 min, because of the cool down cycle.
have had this TV for 8+ years, the first 5 years it ran about 14 hours a day = 25.000 hours.
no lamp lasted over 18 months. over the 8 years 2 have lasted 18 months some as little as 6 months all but one were Osram the other was a PHILIPS it ran 12 months.

lost a lamp due to power outage in the 8 years, it was about 11 months old.

put the kill a watt back on it, after it is off for hours it gave a reading of 52 watts at the highest i've witnessed.
it will never read 1 -10 watts. my guess is the built in DVR ???

my Mitsubishi WD-62827 DLP 8+ years now,new Lamp and mirror & lens cleaning last year and she's like new again. sweet and she has over 33,000 hours now.the most important reading you might ever do.

I've had my WD-65736 now for 5 1/2 years and the wife noticed it getting quite dim so I checked and it has 12200 hours of service on the original lamp. I couldn't find the method of determining the service hours so I came on the forum and ended up googling the net to find the service manual. The command needed was MENU '2' '4' '7' '0'


My usage works out to around 6 hours a day. The set gets turned off every night but I don't do anything to interrupt the power at the power strip. I'm not too worried about standby power.


I've ordered a replacement bulb and will be taking apart the lamp housing to install it.


Still quite happy with the set after over 5 years with it.

12200 hours on the original lamp is amazing! I think you're going to be pleasantly surprised once you install the new lamp. You may even need to adjust the brightness/contrast because the picture will be dramatically brighter than with your 12200 hour lamp.

Yes, I'm counting on recalibrating the set with the new bulb

Checking the web I can't find a way to reset the lamp hours. I received the replacement lamp yesterday. It is well packaged and comes with a paper showing how to confirm it to be an authentic Phillips bulb. It seems that knock offs have taken to using Phillips packaging but real bulbs can be confirmed by markings directly on the glass. Will install it on the weekend.

with housing ?
either way check out the lamp in the set. all my Mit's came with OSRAM lamps.
i tried 1 Phillips in my 8 year old dlp and it did not work better or last longer, just cost more.

edit
after talking to the wife about these lamps, we noted the 44 month old WD-73C10 has only had 1 new lamp. the first one just got dim and replaced it after about 18 months. she runs 16 hours a day.

replacement
26 months x 30 days x 16 hr = 12,500 hr
shes pretty dim now.... compared to the Vizio 60'' we picked up this week lol

Indeed, the original lamp (left picture) was an OSRAM. It had not completely failed but had managed to get hot enough to pivot the element some 30 degrees.


The replacement Phillips bulb (right picture) has a different terminal connection point which barely allows the high voltage lead to reach. It's back together and MUCH brighter now

the heat off the lamp is pretty hot. in my older set the plastic housing that holds the lamp housing was deformed long ago. it went inward and makes getting the lamp housing out a pain. looking at the hours on the 8 years set over 33,000 hr now. dang

hope you enjoy your back to near new set.
