ASK Proxima C420 shuts down after 30 seconds. No indication of overheating or lamp problem.


Might be a problem with the video input. Try a different cable. If HDMI, you will need a really good cable for HDTV or 3D, and they are very expensive. My 12 foot cable cost $180.

I have a Sony SXRD KDS-R50XBR1 and the tv keeps shutting off and turning back on. While its off the green power light flashes. I just had the lamp replaced and the optical block replaced a few months...


Green light flashing is normal as the lamp warms up before turning on.
If it runs for a bit before turning off it's likely to be overheating somewhere.
Looks to be more than one fan in this so possibly dust in one of the others but there should be a "High Temperature Warning!" message if it's overheating. This set has a "high altitude mode" for extra cooling.
If it turns on and then turns off again instantly it might be something has failed.
There is quite a detailed service manual if you want to have a look for possible clues:

I get a message that the air flow/fan is blocked, then the tv shuts down. It's not blocked. It's perfectly clean.


This indicates the TV is overheating. Lamp based TVs usually have two or even three fans. One may be having problems or not turning fast enough.

About how many hours are left when the replace lamp message comes on?


usually between 0 and 50, depending on how clean you keep the projector. if it's really dusty, the lamp could explode from overheating at any time.

I just replaced the lamp about 5 days ago on a mitsubishi wd-52631.it has worked fine until this morning,I turned it on and it said overheating check airflow and shut down.yellow light is on,tried to reset...


call Mitsubishi they have a recall on this particular problem. It has a thermal sensor that needs to be replaced, they are picking up the bill on this so it's not suppose to cost anything for this repair.

Mitsubishi HC900 Projector shuts down after 5 minutes.


You have 1 of 2 possible problems.

(1) You need a new lamp.

(2) You have an overheating problem.

Just a quick couple of notes about your projector. It is a DLP projector (not LCD) and as such the machine as no air filters to clean. It does have air intake and air exhaust grilles, but no air filters to clean. This next part comes directly from the owner' manual for your projector:

When the lamp operation time exceeds 2000 hours*1 *2, the projector automatically shuts off and can’t be used until the lamp is replaced and the lamp operation time is reset.

Your machine is designed to give visual warning messages at 1500 hours used, and 1900 hours used. Did you see any visual warning about lamp life over the past few months?

If you were experiencing an overheating problem, a "TEMPERATURE!!" message would flash up on the screen just before the unit shuts down. If there is no warning, you don't have a heat problem.

If you have a replacement lamp available, install it and reset the lmap hours according to your user manual. If you don't have the manual, google it on the web (it available).

Lamp will not strike error message


this can sometimes indicate either an overheating issue, a lamp service life problem, or that the cover to the lamp housing has not been secured properly.
