The manual says it might be because the power went out when it was on. Just a note here, as projectors age they become more sensitive to power outages. When not in use turn off completely if you can. They have an on/off button.

Otherwise not sure but think you may need to replace the fan. Try cleaning it first but gently.

Smetimes the other fan comes on when set to full bright. As your lamp is not lighting up, the other fan will not come on. If yo have replaced the lamp and it is still not working, then 9 times out of 10 it is will be the ballast.

It sounds like the high voltage portion of the power supply (ballast). Turn to the solder side of the P/S board and orient it so the silkscreen is legible. Check for burnt resistor R573, 2Kohm. It's center of board, 3/4" from bottom edge. If that's OK, check 3.3kohm resistors R621, 622, 625, 628, 629, and 630. They're in the top right corner. They tend to crack. Good luck.

Your new bulb is not lighting.

Once you replace the lamp you need to go into settings and reset the bulb hours back to zero. That will take care of your problem

I just replaced my bulb on the toshiba tdp t45u projector and the red lamp light is still on and the projector still wont come on? how do i fix?


Check out the Power supply to the lamp . It must not be high . . Check if the voltages are correct to the lamp's unit and it's PCB [printed circuit board]. I recommend using a service manual .
.............................................................

Here is how to replace a projector's bulb correctly :

1:Make sure that your power switch is off and that the power cord is unplugged from the electrical socket.
It is also wise to unplug any other cables and label them in order to restore them in the right way once the lamp is replaced.


2:In order to see the lamp, remove the access handle on the outside cover. You may need to use a screwdriver.

3:Pull out the used lamp and clean the relevant parts using micro fiber products and not paper.
Please note that in some projectors a small inside filter should also be replaced.


4:Insert the new lamp into the projector carefully avoiding touching the glass of the lamp itself.
Touching the lamp will deposit skin oil that will likely damage any new lamp during use.





5:Reassemble the access panel, replug the cables and power up the projector.

Things You'll Need:
new projector lamp
screwdriver
micro fiber duster
Warning:
avoid touching the bare projector lamp
I hope this will help .

Standby light for toshiba


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.

Bulb light projects red


Hi there

I guarantee you 100% that this not a bulb problem but rather a Mainboard failure.

This can unfortunately only be resolved by having it repaired or replaced.

And it is expensive incase you were wondering.
