My almost 1 month old mitsubishi wd-73733 is turning off by itself apparently. Has anyone been having this problem? I dont have an extended warranty and im not sure if it has been 1 month. I am going to go to bestbuy today to talk to them about how the tv is acting up. What would be a good TV as a replacement that is around 70" and is around the same price range of 2500. How can i fix the problem before i try to get the tv replaced.

According to the manual, the tv shuts off to prevent it from overheating if 1) the ambient temperature is relatively high or 2) there isn't enough clearance behind and around the tv which would cause it to overheat.

How long does it take for it to turn itself off? 1 hour? 30 minutes? 1 minute? Is it consistent?

Then it's probably due to overheating, but that's a bit disconcerting. If the room temperature is normal (~ 70F to 76F), it shouldn't overheat like that. I mean DLP TVs in showrooms like CC or Bestbuy run all day long and I'm sure they don't overheat and turn off mid day. That would be bad for them. Make sure you have a clearance in the back for good ventilation.

lets not jump to conclusions. it seems there is alot of missing information as to what/when the TV shutsdown.

what source is being used?
what do the led indicators show?
what is controlling the source?

There are many reason why a TV will shutoff...or turn off...as the case may be.
Next time it happens press and hold the input and menu buttons on the front panel and check the error code.
It will give you a good idea of what is happening.

I noticed before you mentioned that as well.
Thats why I said we need more info.

Maybe your mom tuned to a source device that was not powered on. in that case the screen would turn blue and the TV would shut off in 60 seconds.

In the above case mentioned by someone else. You would recieve a yellow LAMP LED indicateing over temp I believe.

for error codes...buy or download the service guide from mits.
