Question about InFocus LP 70 Multimedia Projector

InFocus LP70 - Low level output and very blurred

My uncle was told that it would cost £250 to repair as it needed a new lamp driver. He has given it to me, so if I can get it going it's mine. I have opened ir up and don't think it's the driver card as sitting on the top is a board with some very melted components (surface-mounted caps and diodes). I can replace these, but don't know what their values are as they are so badly melted.

If anyone has opened of these up, or has a circuit diagram I'll be very interested to know the values of the components. I can send a digital image of the damage to anyone who may be able to help.
Thanks in advance
Steven

If something went wrong to melt a few components, chances are more are bad that you can't see. it's best to replace whole board.

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.

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. www.avsolutionsny.com

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.

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.

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 projector lp70


in order for the lamp to strike and stay on, the fans and the colorwheel must be spinning and up to speed. if you remove the lamp and start it up, see if the 2 fans are spinning. and look inside to see if the colorwheel (a colored glass disk) is spinning. you'll also be able to hear a high-pitched squeal coming from it. unfortunately, you'll need to take it in to a repair center to have them replaced.

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.

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.
