Check air flow and filters are clear, it sounds like it's overheating.

SOURCE: projector automatically shuts off immediately after turning it on

If your comfortable w/surface mount troubleshooting and soldering, download the service manual from elsewhere online. Part of the troubleshooting tree for this type of problem is to check the surface mount fuses on the underside on the Main PWB (schematic page 1/8). On mine, the 12V surface mount fuse, F3004 (2.3A) was open (quadrant C1 on the schematic). Replaced it, reassembled the projector (3 interlocks don't 'cha know) and it came up just fine.

SOURCE: Green light flashing and then shuts down

Hi Gary

Have you resetted the lamp timer ? It must be done when a new lamp is inserted into the unit.

You can reset the lamp timer by holding the up arrow key on the Projector in until a online message appears. Then just follow the on-screen instructions.

If the problem persists , you will have to replace the Ballast wich is the lamp's power supply.

SOURCE: Toshiba TDP S8 projector shuts down suddenly

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.

With power available at the projector and the lamp off (projector off) - hold the input button on and press the power button on and hold for 5 secs. This will reset the lamp timer to zero.

I wish they could have stuck this in the operators manual.

Problem with eyeclops video projector...after


unplug all rca cables from your eyeclops, then try all three colors one at a time, into the yellow colored hole on the side of your eyeclops, until you get a picture, and you have to have the dvd player on and playing a dvd, otherwise the light won't come on your projector, then plug in the audio sources, the yellow and white. When I got my eyeclops mini projector, it wouldn't work at all when I plugged the yellow rca cable in the yellow hole on the side of the eyeclops, the red into the red, and the white into white. Only when I placed the red rca cable into the yellow hole on the eyeclops, the yellow into the red hole, and the white rca cable into the white hole did it finally work. That was for my dvd player. With the video game function, I plugged each color Rca cable into their same colored holes on the eyeclops and it worked fine, but again, you have to have your device, whether it be a dvd player or game system on and running before your eyeclops led lights will turn on. Not sure I had to switch colors when I played my dvd player, but that's how it works on my mini projector, anyways.

Check that you replaced the lamp in the right way, and also that the unit is well reassembled, you may also need to reset lamp counter from menu on some model.

The sound came from the switching power supply and the lamp ballast circuitary. You need to replace the color wheel sensor, I can fix it.

Projector turns off after about 30 minutes. What's wrong?


your projector status means the protection circuit is working or the lamp is in an abnormal condition.
--wait until status indicator goes out and press power button.
---if the above solution is not working change the lamp.
