Dark shadow

Uh Oh! Your light engine is warping a little from overheating and is distorting the picture. It usually means replacing the light engine.

My suggestion to you is to get on the phone with Samsung and start complaining, then keep complaining until they agree to pay for it. You may have to get the problem diagnosed by a pro before they agree to pay for it though.
Hope ya fix it!

If you are getting the same problem with both TV monitors it could then be assumed it's an input problem to the TV monitor. If you are using a digital output from your receiver it could be the cabling. If you are using an analog output from your receiver it is probably coming from the receiver.
Digital video processing does have issues with darker scenes.
Can you try another video source seperate from the receiver like a DVD or better yet an analog VHS, if you still have one. Good luck and let me know.

Dark band on left side, Samsung HL-R5668W

the reflecting mirror is likely loose and falling down inside the light reflecting tube. you should have seen the band getting darker and larger,
the small mirror is in front of the lamp and bends the light,
remove the lamp and look down the tube (light path)

I have read about this issue many times,
it is the mirror inside the light tube that is coming unglued , you have to take it apart and reglue the mirror in place.
I think if you remove the lamp you can see the mirror down the tube.
use some high temp silicone to reglue it.

Don't recommend replacing the light tunnel if you never had any experience with DLP optical systems. you need to pay careful attention to the way you remove any screws or you will be forced disassembling the engine multiple time to get the alignment correctly.

Dlp problem

The unit has a defective light tunnel contained within the light engine. This part is not easily replaced and you will a qualified tech to replace it. Many service centers condemn the light engine at a much hight cost. Do not buy or let someone tell you the light engine must be replaced. This repair requires only the light tunnel.
