Either the lamp needs to be replaced, or your projector is experiencing overheating problems.
The unit may not be running hot but there may be a bimetal thermal switch that has become fussy.
If you have an electronics supply nearby, they will have 'freeze spray' and if you procure it, you can see if the projector will turn back on if you give it a shot in a vent. Do NOT spray it on a hot lamp; it may cause it to fracture. If this does make it turn back on, you will have to locate the failing switch although the common ones are disc-shaped with two contacts coming from them.

Red power, blinking red temp


Hi,

if the Lamp error and Temperature error lights are flashing red this means that there are two separate errors.

  • A flashing lamp light means the lamp failed to ignite. It could be a lamp driver problem or lamp failure. Replace the lamp to resolve the issue. If the issue is not resolved, then service the projector.
  • A flashing Temperature light signals a fan error. Turn the projector off and allow it to cool down. If the light is still flashing after the projector is turned back on, service the projector.
Goodluck..

Benq w1000 project not turning on


Look at the manual page 34, for the indicator messages. I suspect it's the same problem I have (which I haven't had formally diagnosed yet!), which I believe is a defective fan. My projector had been making a really loud noise on startup, which varied in length and volume. Recently the projector has taken to turning itself off after being on for about a minute, and the power light flashes green, with the temp and lamp lights flashing red.

Right after startup, the temp light comes on and the projector shuts off.


The thermal switch could be bad, but I'd say that there is a fan not working. A model number helps when asking what is wrong with your projector.

What does it mean when that blinking green light turns to orange one in lp 350?


Hi
This would be "Standby"
When you press standby, the display and audio turn off and a blank screen is displayed for 15 minutes.
You can change the amount of time the projector stays in standby mode; see “Standby Time” on page 27 for details.
The LED lights orange while the projector is in standby.
• If you press standby again within 15 minutes, the projector returns to normal operations immediately. The LED changes from orange to green.
• If you press standby again after 15 minutes, there is about a 60 second delay before the lamp turns back on. The LED flashes green while the lamp is re-lighting.
• If you don’t press standby again, the lamp turns off after 15 minutes. The LED lights orange while the projector is in standby.

I hope these help

Toshiba TDP-S20 lamp problem


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
