Question about ASK Proxima InFocus LP70, LP70+ and Proxima DP1000X, M2, M2+ Lamp - SP-LAMP-003 Projector Lamp

Open Question

I have this ASK M2 DLP projector ( equivalent model is infocus LP70) which has hardly been run for 10 hours. When I switched it on, there was no lamp lighting up and there was no diagnostics error. After removing the top cover, the color wheel is not rotating although there is a high pitched noise ( probably from ballast circuit). The projector is brand new. Any help as to what is wrong will be greatly appreciated. I live in india and there is no INFOCUS repair centre in my city.

SOURCE: DLP Infocus Problem

first of all, the infocus lp 790 is an lcd projector, not a dlp. second, the light filter in front of one of the lcd panels is burnt, and unfortunately cannot be purchased separately.

It is not a common problem. Ballasts rarely need repairs. Have you reset the lamp hours to zero after installing new bulb? If, yes to confirm about ballast please ask the TV repair shop man whether previously he had repaired any DLP projector. There is lot of difference in technology of DLP projector & TV (except DLP Projection TV). The problem could be in the projector main board. The lamp lights after getting Lamp ON signal from the projector main board. As the lamp ignites the ballast sends the signal of Lamp Lit. If the projector board senses that any blower/exhaust fan or colour wheel is not running then it will send a signal to Switch OFF the lamp. If you are tech-savvy then do as follows to check about lamp & ballast. Remove 5 pin connector from the projector. Connect projector to mains supply. Get a 5V DC power supply. Connect +ve to pin 3 & -ve to pin 4 of the ballast connector from this supply. The lamp should light. If it does not light then there is problem in the ballast (if the lamp is new). To give a chance you can check it for your lamp which lasted 20 minutes. Generally ballasts are made by OSRAM. You can get the ballast from OSRAM dealer. You will need the part number for that. Take out the ballast, it is there on it.

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.

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


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.

LP70 lamp will cycle on and off in 3 min. intervals.


go into the menu and check the lamp hours. if it's over 2000, you need to replace the lamp. if it isn't, the power supply and/or ballast is starting to fail.

Why does picture brightness change up and down on LP70.


Hi there

Sounds like the lamp is going , but it could be the Ballast as well ( lamp's powersupply ) Rather have a certified technician look at.
