To re set lamp life - Mitsubishi WD-62531 Projection Television

This set and the one before it (50lc13) had so many problems the latter was recalled and all were exchanged.

Someone would have to open set and check power supply first--set is not real easy to work on.

The recall involved issues where the sets were eating lamps up alive--very short lamp life---solution at first was to rebuild/replace the Ballast which drives the lamp.

Average life should be 2 years or 2,000 hours on that lamp.

It could be the lamp depending on the replacement you installed. Some of the Generic last a year or less--original or OEM have a 2,000 hour life and that determined by how much set is on.

First thing to look at is lamp.

NOTE: at the time this set was made in the menu was a Quick on feature---it runs the lamp all the time(when set is off it dims down but does not go out) THIS FEATURE WILL IF ENGAGED DRASTICALLY SHORTEN THE LIFE OF THE LAMP not to mention using more electrical power in your home.

When you changed the lamp did you clean the "lamp temp sensor"? When you removed the lamp housing from its cradle, you can access it from where lamp goes. It can be cleaned with a Q-tip.

Also, there is a little blue safety switch that is located on bottom right of the light engine tray. It MUST be in the DOWN position when the TV back is reattached to TV. You can use tape to hold it in the DOWN position while attaching the back of set.

Also after replacing your lamp did you reset the lamp life?, You can do this by:
1-TV off
2-press mute+1+8+2+Power. This will access factory settings.
3-scroll to "Options". Press right arrow to next menu. scroll to "lamp life" hit right arrow and click reset.
4-power off.

That resets the lamp life hour meter.

it sounds like you need a new lamp, this lamps are rated 6000-8000 life hours a life span of 2-3 years of use most of the time the problem comes from the lamp in this TV sets this is the lamp you need

I have a very good suggestion for you. If the set is working go into the customer menu and look for something called "quick start".

If this set has this feature it is default---means unless you change it that will be the way it is. It was a stupid idea----what happens is if it is there and engaged when you shut the set off the lamp will dim down about 60% but it and the fan will be one 7/24 which tends to shorten the lamp life.

Average lamp life should be at least 2,000 hours.

If you have the set off and turn it on and instantly get a picture, it is engaged----the "idea" was the customer would not have to wait for the set to slowly bring the lamp up to full brightness (about 15-20 seconds from start to finish).

If you turn the set on and get a normal bright picture in under 7 seconds your set has this feature.

The way this works if it is not engaged is when you shut the set off the lamp will turn off completely and the lamp fan will run for a few minutes until the temperature of the lamp drops below a specific level.

Not to mention vastly shortening the life of the lamp, it also is eating power 7/24.


Please let me know what you find and if you have any questions let me know by posting a "comment" here.

Most of these sets the lamp has a 2000 hour lifespan and there is a built in counter keeping track of how many hours the set has been on; Most of these sets when you change the lamp you need to have information to get into the Tech menu to reset the timer to zero.

Some sets that lamp lasts longer and some less.

In the menu of the TV in the video advanced section, you can adjust the fan setting to "High". It may be a little noisy, however it will extend the life of your lamp. If your "low lamp life" has come on the screen, you need to replace the bulb, the next thing to happen is the picture will go blank. Hope this helps

reset the lamp timer. go into the menu options under settings.

Hope helped with this (remember rated this help). Good luck.

Yes you have a bad lamp. Unfortunately, I have noted that many dealers either "forget" to tell the customer that the lamp will require replacement, or they overstate the expected life of the lamp. The usual life of a lamp, as stated by Sony is 4000 to 8000 hours. There are 3 factors that effect lamp life:
1) the number of times the TV is turned on and off. Every turn on works the lamp very hard, so to make the lamp last longer, limit the number of turn on/turn off cycles. My rule of thumb is this: If you will be back to the TV within 30 minutes, leave it on.
2) Proper ventilation. In general the TV should have at least 6 inches of space on all sides to properly cool.
3) Power loss. If you have frequent power outages, buy a small UPS for the TV. The TV requires a "cool-down" cycle where the fans run to properly cool the set. If the cooling cycle is interrupted, it can effect lamp life.

Replace the lamp with and original Sony lamp and vacuum any openings you can see that are dusty and you should be good to go. Be sure to rate this solution. Thanks!
