Maybe start with a good clean out first.

I tend to use those cans of air meant for computers but dont poke the nozzle in too far !

If it still has issues then its time to start opening her up to check the fan and such.

I just replaced the bulb unit in my Toshiba TDP-MT800 projector but when I press the power button nothing happens


Make sure the Lamp is seated correctly and firmly and the microswitch on the lamp door closes. Some projectors require a button sequence to be held down whilst powering up the projector in order to reset the lamp counter and restart it. You could also try the old lamp back in it for a few minutes to see if it starts up using the old lamp, providing it hasn't shattered.
Good Luck

InFocus LP130 Projector has intermittent power off


go into the menu to find out the lamp hours. it could be the lamp, but if the projector shuts down and not just the lamp, there is either an overheating issue, or a power supply issue.

Projector shuts off after about 45 minutes


Just a long shot, but...

I have an epson 9000i that did the same thing. Turns out that unit has a small fan (I think 60mm) right next to the power supply to keep it cool, in addition to the large fan that exhausts past the lamp. The fan runs non-stop as long as the unit is powered-up for two reasons I can think of - keep the power supply a little cooler, and the lamp a little warmer so there's not such a temp difference when it powers-up. Long story short, that fan had died. I replaced it with an aftermarket 60mm fan and it's been working fine ever since. Hope this helps.

HI there

This is a faulty Mainboard that will need either repair or replacement.

If a Projector starts playing on and off tricks I have found it to be 99% of the time a faulty Mainboard.
