![Post Post](templates/standard/images/icon_minipost.gif) Posted: 16:00 - 13 Nov 2017 Post subject: What to do with my old projector? |
![](images/spacer.gif) |

Optoma GT 750 XL
I owned this since new I think I bought it in 2011. At the time, it was one of the best 3D projectors without spending £1,000's on a higher end one, think it cost me about £800 (I think).
Anyway, the bulb finally went a few months back and I bought a new lamp for £120 from AV Parts Master.
Man this thing was bright originally @ 3,500 lumens but within about 20 hours of use, not even... the DMD chip started failing.

It's basically a tiny chip inside with hundreds of little mirrors which start failing and the only cure is to buy a new DMD chip.
Spoke to Optoma and they want £300 odd. Using cheap Chinese knock offs is not an option when it comes to DMD chips either, they are a Texas Instruments piece of hardware and extremely hard to replicate due to the mind numbingly difficult manufacture process / cost.
It works fine but as this chip continues to fail, more and more of those white spots appear.
Reckon I should whip the bulb out and try selling it for £99 or something? And sell the projector as spares and repairs for like £40? |
