Long video is long. I was going to split this into two parts, but I think it works as it ended up. This GT1080 Darbee was sent in because the color wheel was still flickering after being replaced. While I was unable to 100% verify the issue, I suspect it was due to the new lamp not having the proper IR/UV block coating. I address that in the video. Unfortunately the projector suffered some truly awful damage in shipping (please use more packing than you think) and the casing, optic assembly and the mainboard were broken/crushed/assaulted. Normally this would be a "scrap" unit and anything remotely useful would be kept but I had another idea. The owner is a really nice person and while they may not have packed it thoroughly enough, they don't ship projectors and between you and me, UPS store should have helped him out with packing. Anyway, I decided to see how far I could go in getting it back up and running from a total trash pile back to a now Hybrid GT1080-HD26-UF55 Darbee... I figured this would be an interesting way to see how similar many of the models are as well as their differences. The result was a Christmas miracle! It is part GT1080 darbee, HD26, and UF55. The casing is an HD26, the color wheel and light tunnel mount are from the UF55. The light tunnel, lamp basket and keyboard wire are from the HD26. The Optic assembly, mainboard and power supply are the GT1080 Darbee. The lens was scratched but I was able to rotate the scratch out of the image. While not perfect, I think this was a great example of what you can do if you have the scraps around and some determination. *****NOTE***** I would never ever consider this a viable method for repair. If I were to actually charge someone for this amount of work, it would exceed the cost of the projector and then some. I only did this for the fun of it, to make the video and help out a nice person. Do not take diamond Dremel wheels to your optics, nor should you swap light tunnels and chassis around. Not unless it's your only option. Merry Christmas to everyone who celebrates and best wishes to everyone now that we almost made it through 2021.
