If the fans go off imediately too, it's the power supply. if the fans stay on, it's either the lamop, ballast, or colorwheel. either way, you may need to send it in to an infocus service center. try av solutions in ny. they're really good. www.avsolutionsny.com

SOURCE: Infocus LP70 dropped and now

try pulling the outer ring out a little while twisting it (you won't break it). then try the inner ring. if it wiggles, you need to take it apart- and that's not a pretty job.

SOURCE: 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.

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.

SOURCE: InFocus LP70 color problem

No it's not the color wheel. If the color wheel stalls the lamp will shut off immediately which is a built in protection mechanism. On the LP70 and 70+ there is a multi pin connector inside located at the rear lower left of the projector. This connector connects the main board to the DLP engine electronics. This connector is horizontal and approx 2 1/4" wide and 1/4" thick and about 100 pins. I have seen this connector not seated completely and many various video artifacts occur (even the one you describe) If you or someone you know is electro-mechanically savvy it's not difficult to open the projector and make sure this connector is seated properly.
You will need a TORX T8 screw driver.

Cheers

Screen keep jumping


This is probably a voltage issue with the power supply especially if it is an LP70 type projector. If not it is still a power supply problem that will have to be fixed.

if you are talking about the ribbon connection on the rear of the main board, then yes I would scrap it unless you want to try and find a LP70 on E-bay to use for parts. You may or may not get a good board but if the price is under 50 bucks it may be worth the risk.

LP70 Infocus Projector light will not start up


if you don't hear a high-pitched whir, the colorwheel needs to be replaced. if you do, it's either the lamp or ballast. if the lamp is new, replace the ballast. you can get the parts if you want to do it yourself, or you'll have to send it in. either way, try av solutions in ny. they are an infocus service center and they're really good. www.avsolutionsny.com

InFocus LP70 projector is running hot


clean the dust out of it with canned air. the dust keeps in the heat that the projector is trying to expell. it also shortens the life of the lamp.

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.
