Question about InFocus LP650 Projector Lamp

1 Answer

Two horizontal black bands across the lower 1/3 of the display.

The unit is a INFOCUS LP650. The height of each band is about 10% of the screen height. I have reseated the mother board and checked the display connector.
Also looked for bad solder joints .

Any help would be greatly appreciated.

    I have a similar problem with a Infocus 7205.

    Its one horizontal (grey/black) thick line/band through the image.

    I got this projector as a gift from a family member, they had the same problem, but when the projector was moved it seemed to have fixed itself. But now the problem is back!

    I too was thinking it could be a loose connection / bad soldering - and am planning to open the projector up soon.

    Was wondering if you have had any luck with a solution as yet??

Hello, im looking at buying a second hand projector, how do i find out the life of the lamp? can i look in the menu? if its on it last legs, and only got a few mouths of use left in it, are there still...

you can view lamp hours in the menu. Keep in mind, however, that there is also a reset for the lamp hours, so there is no way to know if the reading is accurate or not.

lamps can be purchased at:

As you can see, new lamp is probably way more costly than what you are paying for the projector. Why not just purchase a newer, better projector for same price as replacement lamp?

InFocus LP600 - A vertical shadow on the Left-side covering about 20% of screen.

The light tunnel inside the "engine" is either out of alignment or the glue holding the tunnel together is coming unglued and 1 of the 4 sides has fallen in. There are 2 screws to adjust this if the tunnel is still intact. One or both screws can be accessed by opening the lamp door and then you have to remove a thin sticky cover. You will see 2 small screws that will have to be adjusted with a small torx (3) or allen. You will have to have the safety switch pushed in with something and adjust while the projector is on, using the most easily accessible screw, turn it towards the direction of the "banding". It should decrease. If not, turn the screw the other way. The screw that is not so easy to get to is for adjusting the banding the can appear across the top or bottom of the screen. If the banding gets worse or even starts to show diagonally across the screen, it is a good bet that the tunnel has collasped.

check the colorwheel. if the colorwheel doesn't spin, the lamp won't light. if no fans come on either, replace the power supply.

I would replace the fans with a higher CFM fan. You can google the size fan you have and something should pop up. The stock fans are about 20CFM. You can get fans with over double that for about $5. Let us know if it works!

InFocus LP650 will not come on

First try a firmware upgrade. If that doesn't help, it seems it might be a power supply issue since you said the led comes on very light. I repair these power supplies. My ebay id is gtitubro

I seen this problem with lamps that are not from infocus. I would recommend to replace it with the old lamp fan. if you still have it. I'm not sure why it does this.

I want to test my infocus lamp to know if it is burnt

Your lamp might be ok, but you power supply is dead. If your not seeing any led lights come on when the power cord is plugged in then your power supply is dead. I can fix this for you for less then it cost to send to infocus or to a repair shop. Ebay Id is Gtitubro

InFocus LP650 will not come on

That color is not listed because it is either Green or Red. There is no Blue, if you are getting Blue, you have something that is extremely unusual.
