InFocus IN24, Dark Spot in center of Image, Plastic Prism Behind Lens for an InFocus IN24

Noticed that several members have asked the question but no clear cut answer was ever given.. I purchased a used InFocus IN24 for relatively little money from a garage sale.. The previous owner gave up trying to fix it.. Complaint: Large Dark Shaded are in center of image.. Since no warranty and little investment thus far; I decided to dive into to it. Found the problem to be the Plastic Prism behind the lens.. It has a "caked on" burnt spot in the center of the prism.. Now here is my problem.. No Part number and InFocus Tech Line was of no help.. They directed me to EDexdeals.com and that was a dead end as well. Does anyone out there know the exact name to this part or better yet, know the part number to this item that I have described? Any and all help would be greatly appreciated... Thanks...

SOURCE: Tranlucent dark spot on Optoma image. Looks like

is it an optoma or an infocus? if it is the infocus, it needs to be replaced. however, to replace it, you need to remove the entire optical engine. now off of that, remove the clorwheel and clip, the main board, and the tunnel (on this model it is called an integrator rod) assembly. to get that out, remove the 3 tap screws and the large screw. once you can slide it out, remove the foil from the front, slide out the inside tunnel assembly, remove the clip, then the tunnel. because the clip is an exact fit, you cannot have anything on the tunnel that increases the size. reverse the instructions to reassemble (but you will need to replace the foil with a new one). warning: you now need to realign the tunnel using 2 of the tap screws. if you have not done this before, it is very difficult and dangerous, as you need to have the projector powered on and the screws are way inside next to the power supply. there is a risk of electrocution and damage to the projector. best bet- send it in to an authorized infocus service center for repair. try av solutions in ny. they're really good. www.avsolutionsny.com

There is a lens(looks like a small magnifying glass) made out of plastic that the light shines through to focus the light on the mirror before it hits the DLP chip, that lens is Melted in the center. I unfortunately had the same thing happen to me, and I am unable to find a replacement part.

If you still have the owners manual there should be an 800 number or some sort of customer support for it. Unless it's really old that is your best bet for the internal pieces

Where could I get the plastic lens for my infocus 61md10


Remove the little plastic lens and throw it away. There is no replacement available anyway. Reassemble the tv and it should work fine. Mine has been good for quite a while now.

If you are experiencing a colured blob, usually lack of blue producing yellowy stain. The cause is excess heat on the blue LCD panel. This is a replacement job on the panel as it won't recover.
Keeping the air ways clean and filters clean will help to stop the growth.
Hope this helps.

Take off the front bezel, then remove the screws from the lens,pull the lens out and blow it out with compressed air. Do not touch the mirror or magnifier inside. If this doesn't get all of the blemishes, then you will have to remove the top cover and then the top silver part of the engine and blow it out from the top.

Dark spot issue.


Its an acrylic condensing lens inside the light engine that has melted/warped. You have to pullout the entire light engine then disassemble the optical light tunnel to get too the lens. Then you need a lens-smith to cut a new lens because Infocus won't stand behind this design flaw. Its really a shame on Infocus!
