Question about Toshiba TDP-S20U Multimedia Projector
I have a Toshiba TDP-S20 projector that will not power up the lamp.
It initially has the standby lights illuminated, but when one tries to power the lamp up, there is not even a flicker, and it then flashes a red lamp light on the top panel - which suggests a fauly lamp.
Now the lamp is good (and so are the 4 spares I have) as I have put them all into another unit and they all power up. The colour wheel is spinning, and all board connections seem to be in order.
Is there a secondary power supply that kicks the lamp into action?
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
