My first lamp failed after 900 hours, I purchased a second lamp part number TLPL-MT8 from partstore.com. The fan failed after around 250 hours. Can the fan be fixed? Do I need to buy a new lamp? Can I expect a free replacement? The lamp was $450.00, so I would like to not have to replace them every 3 months! Any suggestion would be greatly appreciated.

Re: 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.

Hello Look at the number of blinks of the status light.  If it blinks at one cycle (0.5seconds On and 2.5seconds OFF) : Lamp cover error or lamp housing error. Replace the lamp cover or lamp housing correctly.  If it blinks 2 cycles (0.5 seconds ON and 0.5 seconds OFF): Temperature error. The projector is overheated. Move the projector to a cooler position.  if it blinks at 4 cycles (0.5 seconds ON and 0.5 seconds OFF): Fan error. Fans sill not work correctly.  If it bliks at 6 cycles (0.5 seconds ON and 0.5 seconds OFF): Lamp fails to light. Wait a full minute and then turn on again.  If it blinks continous (Red): Lamp has reached the end of its life. Lamp replacement messege will be displayed. Replace Lamp with same type and number. After replacement reset lamp hour. OK.
Your lamp is rated for 3000 hours. Is the fan working to cool the lamp? When you turn off the projector do you allow the fan to continue to run? If not the lamp is not cooling evenly and the lamp will fail. Th filters should be cleaned regularly and the vents be unobstructed.
The lamp is generally rated at 2000 hours so I would say you have done quite well. You must not watch too much TV as that would equate to a little more than 1 hour a day. There are a number of online resources where you can purchase a replacement lamp such as partstore.com and others. As I recall you will need to remove the lower trim panel to expose the lamp compartment to gain access for replacement. One key to long life on any set that uses a high intensity lamp is to allow the TV to go through its normal "cool down" cycle. Never have your sets AC power interrupted before the set cools down. After the set is shut off the fan keeps running until the unit cools sufficiently. This prolongs the life of the lamp. Some stores would have all their sets on a power strip and cut AC power instantly at the end of the day and consequently replaced many expensive lamps that could have lasted much longer.
This symptom can be caused by a few different conditions. Do you hear the fans running? If not then possibly the over temp protection switch has failed. or the lamp cover is not securely in place.
If the fans are running (you can feel air flow) then either the lamp has failed prematurely or the lamp power supply (ballast) has failed or you have replaced the lamp and failed to reset the lamp timer and it has reached it's limit which can be reset by pressing both the volume up and volume down buttons on the the projector simultaneously for 10 seconds. This will reset the lamp timer.
