Need a light tunnel for the light engine

Anyone know where I can get a replacement light tunnel for the light engine of my Optoma RD50? I'd prefer a new one, but a good used one will do. Thanks!!

I replaced the bulb on my optoma ep1691 projector but the picture still goes out and the red lamp light lights up. I reset and confirmed the reset via the menu. How can I resolve this issue?

It seems OEM lamp that was replaced in projector is not good, please return this lamp and ask another lamp to solve projector problem. Projector seems fine and has no issue, it is replacement low priced lamp that is causing problem.
I would recommend to buy original lamp from Optoma Support.

I replaced my RD50's lamp recently and everything works perfectly, but the notice telling me that it is time to replace my light continues to display every time I turn the set on. There is probably a way...

There should be a reset lamp function in the service section of the menu. If there isn't, there is a way to do it by pushing and holding a sequence of buttons on the tv or remote. It varys from model to model. Check your manaul to see what the correct proceedure would be for your model.

HAve you been ever replaced lamp? check the lamp first, then ballast and power supply. The black is possibly caused by light tunnel. If this happen you can call Samsung for a replacement free of charge for the first OOW.
Chaging the light tunnel needs trained person to do it. IF you could DIY, here how you take it out. Take off the cover and pull out copper cable and smal cables connected the color wheel with DMD board. Then uncrews 2 screws holding the color wheel. Pull it straight up vertically to avoid it to be broken. The light tunel is opposite with the colowheel. There are 2 small screws to fix light tunnel. Turn out and remember to count how many turn. Nomally, it is about 2and 1/2 turns. Put the new mirror in and screw it back. If you are lucky, you need not to do adjusment. Else you have to adjust it few time to get all shadow out.

I have no power from my power supply. Is the power supply bad or is there another cause for this. Knowing that there is outlet power present, I have nothing indicating power at output of supply.

Nothing coming out from the power supply would signal a bad power supply. The power supply is bad. Replace it. It may have blown a fuse inside.

Long story short: The blue fog problse is the light engine. Specificaly, the filter for the blue LCD gets to hot and over time starts to burn up and disinigrate. (I just tore my set apart thinking maybe it was the blue panel and found this was indeed the culprit for this problem). As far as a solution? You will either need to replace the light engine (expensive) or replace the light filter which means tearing the thing completely apart. then there is the problem of where to get a replacement filter. Does ANYONE know where? As far as the lamp goes, might be time to replace it. You might be better off just getting rid of that TV and get a new one.

A month from purchase you shouldn't even bother yourself with this. Their problem.... give the shop/samsung a call. If you have no reason to suspect any cable problem, and a different input device(other than the DVD) doesn't affect it, don't waste time and get on the phone. Good luck
