We have a Toshiba TDP S9 projector, it runs for a few minutes and then the lamp light goes amber and then red, it then switches itself off. We have checked that the flilters are free from dust. Please help
There are for each fan - PWM (puls wide modulation) indicators . Mostly the colour is a yellow wires, the other colours are red and black . I have somewhat the same problem that turns the projector down and want to find out if our what fan runs slower then normal . If i found out then i would try to disconnect this puls modulator cable from the input (fan) and try to parallel the yellow cabel with a good working fan , hopefully it works as a surrogate input puls .
We have the same problem at times with about 50 of these units and have sent most of them back to Toshiba for repair. It was found that the fans either stop or go slow if the projector is mounted upside down, but are OK if mounted on their feet and as you know, in a classroom most mount upside down from the ceiling.

1,the color starts to go out, it become the white and black ,
2,then,the projector running off after only a few minutes,
it is a general issue:the inductor need to be cleaned
Use a cotton swab moistened with alcohol to clean the inductor.
the inductor (Sensing element),is near to the Color Wheel.
the industor : is a black little element,as little as a sesame seed
any questions, feel free to ask me
have a nice day!

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
Things You'll Need:
new projector lamp
micro fiber duster
avoid touching the bare projector lamp
I hope this will help .
toshiba is not one of the most rliable makes im afraidi have seen this fault before and it turned out to be the bulb which i had recentley replaced and this was apparentley the wrong one and gave the same sort of results.
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.
The reason why the projector is shutting off is so the lamp doesn't explode. It's more of a safety feature on the projector, you can reset the lamp and it might work for another 500hours. If the picture is still pretty bright I can get you the reset procedure, but be warn that when the lamp does eventually blow it could shatter the glass inside, so be careful, it shouldn't hurt the unit.
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
