Are the filters clean and I came across one with the exhaust fan the wrong way around. Make sure there is lots of air blowing out of the exhaust.

When turning the unit on, powere button changes from red to blue for around 3 seconds, then goes to red off again. Anyone help?

Its due to the complaint of its Power Ballast unit ( Power Control Board). So please contact any one of the service centre in your area.

3M SCP712 projector shuts down after an hour--can't turn back till it cools

the problem is with overheating. Look whether the cooling fan doesn't work or air filter is cloggy with dust. OK.

Sanyo PLC XT11 Device turns on, counts down from 30, and then turns off and uses fan on high in what appears to be a cool down cycle. The lights verify that the device thinks it is overheating. Lamp...

The air filters on projectors are very important.
You need to take them out and clean them regularly, if not projector can overheat.
Also check all the grill are not blocked, using a vacuum cleaner with a brush attachment on a gentle **** is the way to clean them off.

On power up, it seems to start but shuts down in three seconds after starting. The sequence can be repeated with the same results.

i would imagine it is having a capacitor overheating... i just had one with dry joints on the capacitor and it took 4 hours to start up...... hope this helps i would recommend taking it in to get it looked at if you want the projector...... also the capacitor which will be most likely causing this will be located on the main power board which is located in the front right hand side of the projector under the main display board which is held in place b y three screws... cheers hope this helps

I have recently bought a second hand 3M projector, and when turned on the screen shows half Blue (i think) and half Red and when used via the laptop the red shows through on the right hand side, can anyone...

first reset the settings to factory default. you may have to realign the lcd panels and make sure the panel ribbon cables are properly seated. otherwise, you have a main board issue.

Right half of screen is Black with a White vertical stripe

Yeah, I have this exact same problem, except my mom slammed my laptop shut in frustration around half an hour ago, so that's why it's like this. The right half of my screen is black with two colorful stripes (mostly white), but the left half is visible. I've researched a bit and found out that this is because the LCD in your monitor has burnt out, and since you don't have a monitor to attach, the only thing you can do is to go to where you bought the laptop and either get it fixed for free or return it for a brand new one (if your warranty still stands). If not, you might as well get a new laptop. I think my warranty has expired, so I'll get a new laptop, hopefully.

Hope this helps!

I had the same problem with very few hours on the lamp. Sent it back to the factory and they said the fan was overheating causing the bulb to shut down. They replaced the fan and the bulb for free under warranty. I noticed before I sent it the projector was putting out an incredible amount of heat. MUCH better after fan replacement.

Acer PD100 overheating

I found that by resetting the factory defaults the problem goes away. I have experienced this issue a few times after attempting to correct colors.

this projector does not have the best picture or color quality.

Projector overheating and turns off after 20 mins

I have a HP VP6111 projector that works fine on a table top but overheats ( overheating ) when turned upside down and hung from my ceiling. My solution...I went to Circuit City and bought two 80mm computer fans. I also purchased a 12V power supply from Radio Shack. I put one fan on front of my projector and the other on the back of the projector and wired them into the 12V power supply. I mounted both fans with velcro. The front fan pushes air and the rear fan pulls air. The projector now runs fine without shutting off. The fans are 12V and push 34 cubic feet per minute of air. I am very happy with this solution.
