    Once we reset the overheat switch, it works only until we turn it off & need to use it again. Then we have to go through the whole process of taking it apart...again! Any Advise?

Just had the same problem. Based on other suggestions on here I tried resetting the overheat switch, and IT WORKED!

So, you have to pull the 6 screws (one of them is shorter than the rest, remember where it goes) that hold the top on the projector. 3 are on the back, 3 on the bottom - look for the arrows next to the screws.

Put the projector on it's feet, and pull off the top. The button wires will still be connected, so just hold onto the top and find the black circle/shaft above where the lamp is. The shaft has white paint on the top/tip of it. Push it down with a light amount of force. You should hear/feel it click.

Put top back on, put screws in, and you should be good to go.

Don't forget to reset the lamp replacement counter in the menus.

We have a Sanyo PLC-XE40 short throw projector that came with Promethean ActivBoard for a classroom. One day it just stopped working, we cleaned the filter replaced the bulb but it wouldnt power up. We called Sanyo and they wanted it shipped to them to reset the overheat switch. I asked them why we couldnt doit ourselves and they said it was a complicated process but if we had more than 20 projectors then they would be able to tell us how to reset it over the phone. So that got me thinking if they can doit over the phone why not crack it open and check it out, and what do you know I found the overheat switch which has been tripped between two motherboards around the lamp area. I reached in there with a small flathead screwdriver and reset the switch. Put everything together and it powered right up. Didnt have to replace a $400 bulb or send it off to Sanyo and not know when we would get it back. So the complicated trick is to take it apart and press a button. I've also asked Sanyo tech support why they cant tell me over the phone how to reset the overheat switch and their answer was they wanted to provide the outmost support care for their products. Go figure.

Sanyo Model PLC-xe40 We have had this problem with many of the same model data projectors from Sanyo. The solution is to get Sanyo to sort out the persitent problem with this mode. We have sent back all of our data projectors under warranty. The problem reoccurs. We send the data projectors back. It is a design or engineering problem in my opinion.

Dell 1209S Projector, tries to turn on, and the fan comes on for 30 seconds and then goes off again. It tries this several times and then the light bulb icon comes off and it doesn't do antything else


Lamp is burned out or makes a popping sound.
When the lamp reaches its end of life, it may burn out and may make a loud popping sound.
If this occurs, the projector does not turn back on. To replace the lamp, see on page 38.
LAMP light is solid amber If the LAMP light is solid amber, replace the lamp.
LAMP light is blinking amber If the LAMP light and the Power light are blinking amber, the lamp driver has failed and the projector will automatically shut down.
If the LAMP light is blinking amber and Power light is solid blue, the color wheel has
failed and the projector will automatically shut down.
Unplug the power cord after 3minutes then turn the display on again. If this problem
persists, contact Dell™.

I've just replaced the lamp on my Panasonic PT-LM2E projector and it will switch on but no light comes out. The previous lamp blew in the projector after around 2000 hrs. The indicators are as...


I'd recommend checking the fans of the projector, and make sure that they're spinning. Since you've mentioned that the lamp blew inside the unit, bits and pieces of the lamp might have lodged itself within the fans. It might also have to do w/ the after-market replacement bulb, which I normally wouldn't recommend.

I turn tv on...green light comes on but i get no picture or audio....then light indicator blinks red


Hello!
Lamp or ballast(if lamp has been replaced) is bad.
Explanation: green comes on: system works, waiting for light to shine into light engine: no light is coming out of lamp, system shuts down, then you see red! how to determine: pull the lamp out of the unit's compartment. Inspect lamp: bloated stem? shuttered? reflector is not shiny? Chuck it!
Lamp looks good or just been replaced: try ballast. Close lamp compartment without lamp itself. Make sure, door is shut, as well. Turn unit on and listen close to lamp compartment: good ballast will make a buzzing noise, then stop. You've got "red'! No buzzing: ballast quit. Needs major repair! Lamp must be good, for sure, to get to the last part of diagnostics. Conclusion: more, than 2000 hours of usage: replace lamp first!
Good luck,
Alex.

INfocus X1 does nothing after bulb replacement


first off, make sur you have the right lamp (sp-lamp-009, 2 white wires. not the sp-lamp-018, one white, one red. the wires are in different locations in the plug). if you don't hear the colorwheel whirring, that'd be the next step. however, you cannot buy just the colorwheel. infocus does not sell individual parts of the optical engine. but that wouldn't matter, seeing as how they don't sell the engine anymore. also make sure the lamp door is completely closed. there is a peg on it that activates a switch to let the projector know it's closed. if you remove the lamp and use a flat-head screwdriver to activate that switch, turn on the projector. look inside the lamp housing and see if the colorwheel spins. if not, i think you need a new projector. if it does, check the fans. they can be replaced.

Dell 3200 Projector


Hi Tara

This normally indicates that the lamp will need replacement.

The Ibook and this Projector are compatible as long as you run a Microsoft operating system i.e. Windows 98' and higher.

When replacing the lamp , you can just as well clean out the Projector - this is quite important as it prolongs the life of your lamp.

NEC projector LT220 - replaced bulb, works for 1.5 hrs then switches itself off


Hi Matt

There might be a couple of reasons for this problem.

Best is to start with the lamp - return the lamp to whoever you bought it from and insist on a another new one.

If the problem still occurs you should rather take the unit to a repairer - because it could be the Mainboard or the Ballast ( lamp's powersupply ) that is faulty and will need replacement or repair.

Check if your unit is under warranty - because the replacement of a Mainboard is quite expensive.

InFocus LP725 light goes out after 10 minutes


The Projector will turn off after so many hours of running the same bulb module. The counter will turn on a replace bulb LED. Installing the new bulb module should reset the counter and turn off the LED.

Check the projector’s lamp to ensure that it is securely connected
in the lamp module. Make sure by removing it and reinserting it.

Check the cables for problems.

When testing, power up in this order. Projector, Computer monitor, Computer.

A minor power surge may cause the lamp to shut off. Turn the
projector off, wait at least 30 seconds, then turn it back on.

I hope these suggestions help
