    I had noticed that and that is not the issue. even with the lampdoor completely closed we were still not getting any power. Thanks for trying though.

Hi there

Make 100% sure that your lampdoor is closed properly because there is a little swith on the lamp door that supplies the power to the mashine ( only when pushed in ) You'll see on the lamp door there is a pin that stands out - that pin pushed in the switch when the lampdoor is closed thus supplying power to rest of the components.

Tip

Before buying a projector bulb


1. Always be aware of bulb usage hours: bulbs normally last ~ 2000 hours

2. If the bulb pops and goes out:
  • Follow the manufactures safety instructions for this condition.
  • Normally, the bulb will need replacing.
3. If the lamp just turns off:

a. If lamp hours were getting high and the picture was getting progressively dimmer, normally the bulb will need replacing.

b. If bulb hours were low or a few hundred hours from 2000:
  • Clean all filters and air ports.
  • Try the projector again checking overall projector ventilation.
  • There is a heat sensor in most projectors that will shut off the machine if it overheats, so air flow must be unobstructed.
c. If ventilation does not solve the problem:
  • Take out the lamp, following the manufactures instructions.
  • Inspect the lamp bulb visually through the lamp glass window.
  • Look for cracks or damage in the bulb and whether one or both of the lamp wire elements is detached from the top of the bulb.
  • In either case, the bulb is bad and should be replaced by purchase or possibly by warranty if the lamp hours are low.
  • Normally, bulb replacement is the solution, but other issues could also exist.
d. If the lamp looks undamaged and/or you are unsure of the status, the problem could be a lamp ballast, power supply, or main control board issue, and should be evalulated by a technician. Unfortunately, a bad bulb can also result from one of the above issues.

hi,
Did you rest the lamp hour after replacing the lamp. It is recommended the you have to reset the lamp hour after replacing the lamp. For resetting the lamp hour do the following.
1. Power ON the projector
2. Press the Menu button
3. Select OPTIONS
4. In OPTION menu select Lamp Reset and press the enter button.
(If the lamp hour counter is at the heights level then the projector will turn OFF after some time.)
ok

Sharp XR 10X lamp replacement issues


I sent mine in. They changed the bulb and cleaned the unit. The one thing they did suggest that seemed helpful was to upgrade the firmware. They did this as part of the service. That may be your problem, but I don't know that the firmware is upgradable. Yes indeed, they do charge an outrageous price!! I went through Sharp because they would guarantee the work, and I didn't want to buy two bulbs.

Projector Lamps for the Toshiba TDP-MT8 DLP


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.
