Ok fellow brown smudge DbPower T20 users! I may have found a fix. You may want to wait till I get and install the polarizer filter before you order, but…….. they ARE available on aliexpress. See link below. I ordered two for like $15 with shipping, just because it will probably happen again. The projector is poorly designed and doesn’t stay cool enough which heats up the polarizer film on the thin glass and burns it.
It’s pretty easy to get to the part in the projector just follow the tear down guide on ifixit.com and pull the middle glass filter that looks like the item below. Reinstall the new part the same way as the old and reassemble. I’ll do an update when I get and install the part. My guess is it will take a while because it’s coming from some far off destination.
Ok Namaste ;)
