The problem I'm having is on the far right portion of the screen. It's a darkened bar about 3in in width and goes from top to bottom. Is this an expensive fix? Also, I'm only home for a short period before returning to Iraq for the remainder of my deployment so time is crucial. Can someone please help me? Thanks in advance!

You most likely have a failing color wheel. This is a known problem in the RD65. If you search on EBay for an RD50 color wheel it is the same one that goes in the RD65. They are roughly $150 depending on who you purchase from. They can be user replaced if you are handy with tools. The bearings wear out and this causes the humming you are hearing.

The convergence output IC's need to be replaced. This is a very common problem for all projection sets as those amps are high current devices with a fairly high failure rate. The job can be done in the home. Depending on where you live the cost is around $200 to $300.
This is the same problem as other posts have mentioned about the right side of the screen having a bluish-balck stripe down the side of the screen. Here's what's happening. There's a small light tunnel which has 4 very small mirrors located just behind the color wheel. The lamp shines light through the color wheel as it turns and the light goes through this small tunnel and is then relected off several mirrors before it is projected through the lens and onto the screen. Optoma apparently did not use a very good heat resistant expoxy glue when they assembled these mirrors and over time the mirrors drop down causing a shadow effect on the screen. It can be repaired without paying some repair shop a small fortune. Previous posts have a solution from another contributer whihc includes photos. I had to repair mine and it's worked fine since I used a decent expoxy to hold the mirrors.
