Toshiba TDP-MT8 Power LED green/yellow but no lamp even after replacing

I have a TDP-MT8 Digital Projector. The Power LED is lights green/yellowish but no lamp even after replacing the lamp unit. Also, neither the power button or the remote power button turns the unit off - no response.

    I have the same problem with the Toshiba TDP-MT8U from looking around on this website it seems this may be a power supply or ballast board issue?

    A little bit more info: When plugging in the projector after replacing the bulb it just sits there for a little bit then the LED will blink a greenish yellow. The unit is nonresponsive and the fans sometimes turn on and sometimes don't. I had this problem once before but got lucky and once when I plugged in the unit the LED was green and it was back to normal for about 3 weeks. Now it is doing the same thing and I have not been able to get it to turn on again.

Have you contacted Toshiba? They will sell you a new fan. It is possible the power supply has a problem. Bulbs usually have a 90 day warranty. Contact where you bought the bulb. Prices are dropping rapidly for new projectors. Yoiu can buy a new oen for under 500.00.

SOURCE: Toshiba TDP-S20 lamp problem

The lamp ballast which ignites the lamp has failed it sounds like. The red flashing lamp is the tell tale sign with a good lamp installed. Make sure the lamp door is closed too, there is a door switch that can also trigger the red lamp and no startup. There is a company in San Diego CA that can repair the unit called PROJECTOR DOCTOR

SOURCE: Toshiba Projector won't turn on!!!

I had the same. Try to press the "input" and "menue" buttons and plug in the power cable. No control light should be active after that. Press the "power" button and it should work.

I had this same problem & almost threw it away!
If you have had it unplugged for a while just plug it in & make sure the yellow power light is on, then leave it plugged in for about an hour or two. Do not try to turn on before at least an hour, then it can easily be turned on. Make sure you reset the lamp timer option. There & you thought it would be difficult & expensive!

probably power supply or ballast (starts the lamp)

either would be $600.00 or so to repair, probably costs more than the projector is worth.
