Yes this can be fixed, but not as a DIY project. The adjustments require special test equipment and jigs. This unit requires a professional repair.

I have a problem with my ricoh FT3613


As your machine analogue it will suffer greatly from dust build up on the mirrors and this will cause dark copies and shadowing particularly bad on the edges.

Turn the power off. Remove the glass and carefully clean the mirror with a cloth. Do not scratch the mirrors and try not to move the lower mirrors as in some copiers they can cause it to go out of alignment.

It may be other things but this is the most likely and the only one you can fix.

Dark bottom half of screen and dark patch in corner


Thanks for the picture - that's a big help.
It looks you have the dreaded light tunnel collapse common to all LG1.gif DLP TV's. Inside the light engine there is a square tube made up of four mirrors. These mirrors deform and crack with the heat of the lamp. They fall down over the light aperture and cause a shadow of varying degrees. It is fixable now at a realistic price ( used to have to replace engine) as LG have made the parts available. It would take a competent tech around three hours to complete or if you are technically minded you could do it yourself. I hope this helps.
Hope Ya Fix It!

Small bluish, black triangle at far right corner


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.

Shadow on upper left corner


A little late and you've probably already solved it or are just living with it or are disgusted with it and have discarded the tv. But, in any event - here we go. The "light tunnel" bends the light toward your screen. At the beginning of that tunnel there is a plastic lens. The lens is secured with four little feet that a part of the lense. The lens is flat on the side closest to the screen. It fits on the end of the light tunnel closest to the light. The lens probably has a burnt spot. Probably the burn is caused by excess heat which is either a result of a fan failure or a one-time situation where the power went off while everything was hot and there was no cool down cycle. Another item to look at is in the light path before that lens. There is a small "window". It's actually a very thin piece of glass (about 1"X1") held in place by a horseshoe shaped clip and one screw. I think that glass has the purpose of keeping heat away from that plastic lens. If that glass is broken I think you'll have a heat "leak" and the plastic lens will continue to get worse.

JVC AV-56WP30 red "shadow"


The problem called Convergence problem. Unfortunately, some sets have manual convergence boards - which means you can do nothing but replace it and adjust the manual controls on the board itself. But some of the newer ones (Maybe yours) can be accessed through a service mode. So, give it a try and look for a service mode in your set... Good luck!
