Infocus LP70 - It's all Green


The projector intermittently projects an "all green image". No other colors. Not every time, and sometimes a reboot fixes it - Should I do a factory reset on the service menu - or is this a lamp at the end of it's life.

Any help would be appreciated

Re: Infocus LP70 - It's all Green

A tinted image (whether green or another color) is almost always a symptom of a bad or damaged cable - or a loos cable connection. In your case, you'll likely need a new M1 to VGA cable (Part# SP-DVI-A-R).

Assuming that you've made sure that the cable connections are solid at both ends, there is a simple test to verify that this is a cable issue and not a costly projector issue. While the image is tinted green, open the menu. If the menu colors appear fine while the rest of the image is still tinted green it's the cable.

Hi there, my dell projector 1800mp is not projecting an image on screen and it only black lines across. what should I do to fix it?.

After turning on the projector, press "+" and "-" buttons on the control panel

simultaneously for 3 seconds and release the buttons when screen goes blank.

2 Press "+" and "-" buttons again to exit the diagnostic mode.

3While in Self-diagnostic mode, the screen will run a seven-color-cycle test as


Red--> Green--> Blue--> White--> Watchet Blue--> Dark Green--> Yellow.

Ensure that the colors of the test pattern are correct. Contact Dell if the colors are
not displayed correctly.

Light does not come on, fan is working and green light at top keeps blinking off and on on a LP70 infocus projector

if you hear a high-pitched whir, the problem is either the ballast or the lamp. if you don't, it's the colorwheel. you could try to get the parts from an infocus service center or send it in to them for repair. either way, try av solutions in ny. they're really good.

I have infocus lp70 model projector. i replaced the bulb and now it won't light. i put back in the old bulb and the light still wont come on...any ideas? You can tell that the projector wants to run and is...

if you don't hear a high-pitched whir, your colorwheel needs replacing. you can remove the lamp and see the colorwheel inside (colored glass wheel). if you turn it on without the lamp, the colorwheel should still spin. if it does, you have a ballast problem. if not, the colorwheel. you'd still need to send it in to an infocus authorized service center. try av solutions in ny. they're pretty good.

Wont light up

the colorwheel needs replacing. if the colorwheel won't spin, the lamp won't light. if you hear a high-pitched whir, the colorwheel works, which means there is a power supply issue. there is a fix for that, but you have to be good at soldering. if you are give it a try:

InFocus LP70

Have you tried another lamp? Sometimes thats your problem, but I've seen a several occasions that the a defective power supply causes this symptom. Do you see an image flicker before the projector shutsdown? I do have some spare parts for this projector.

I'm on Ebay - gtitubro if you want to contact me through there.

InFocus LP70 color problem

try resetting the settings to factory default through the menu. if there's still a problem, take the cover off. if you look from the back of the machine, inside on the bottom left, you'll see the main board attached by a large white plug. use something thin and non-metalic to push the bottom of the board towards the plug to tighten it. now do the same to the other side of the plug. this should solve it. if it doesn't, you need to replace the main board.

Infocus 4805 blinking red light problem

My first questions is:

Is this the first lamp you have placed into your Infocus pj? If not, did you reset the hours when you did it last time? Otherwise that can also confuse the projectors internal system thinking there is NOT a new lamp in there and there for make it stop working once the clock hours are expired and over the 3000-6000 suggested hour life.

Let me know so I can help trouble shoot other possible problems.

Color not correct on project

Hi there

You will have to find your nearest InFocus repair centre.

But that said , it is the most expensive part on a Projector to have repaired , because they will have to replace it.

My advice would be to rather purchase a new unit.

Pile of ##@!#@ infocus lp70 green light wont come on. should i smash it??

if the fans aren't running, it's the power supply. if the amber is on and the button's won't turn it on, there is an obstruction under the button panel. if all turns on but the lamp and you don't hear a high=pitched whir, it's the colorwheel. if you do, it's the ballast.
