Optoma HD70 Replacement Lens - HELP!

post #1 of 14
Thread Starter 
I recently had to order a new lamp for my HD70, and figured it would be a great time to take it apart and clean it. I have had it apart before, no big deal. This time I decided to try to clean the dust from the mirrors/ internal lenses. No problems encountered until I came to the largest of the magnifying lenses within the unit. This lens is plastic, the others are glass. Needless to say I've scratched it, and it seems to be beyond repair, as I tried to undo my wrong, and only made things worse. Now I am wondering if there is any source out there I can get a replacement lens from. Any help would be greatly appreciated, I really don't want to put it all back together when my new lamp comes only to have the image ruined.

Can you embellish on your attempt to "undo your wrong"?

Have you tried Lens Doctor? I've heard it has a 73.4% success rate, but I don't want to get too specific (your mileage may vary)

I just used basic water and Q-tip to start cleaning the lens, and the protective coating that is on the plastic started to wear away, allowing scratches on the bare plastic. I wasn't even pressing hard.

Does anyone know of a parts supplier for Optoma that I could email?

Avoid this. Their solution is oil based, and as anyone knows, oil and water can make a scratch not as visible, but it is still there. Once the oil evaporates the scratch will appear again.
Have you turned on the projector? Seen what image it produces? I am just wondering, because a lot of times a large part of the surface area is not used for focusing and its only near the center. Depending on where the scratches are, and how deep they are, you may be fine. Though for future reference you really only want to clean a lens with a bulb blower (where you squeeze the air out), or if you must rub the lens use a microfiber cloth, cotton swabs are a bit too harsh.

I would call it a day and get another used.

...and melt the edges of the outer case to seal it and prevent any future cleanings...

so no one can recommend a source for a replacement lens? i can't imagine it's a well stocked item, but it's worth a shot if anyone has an idea.

Parts like that are going to be extremely difficult, if not impossible, to find. The optical engine is considered a complete assembly, available only as that. I have never seen that assembly broken down into the individual components.
