Re: 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.

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!

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.

I have the same problem and was told by a technician that I need to replace the light engine. Probably around $ 700.00.

Samsung DLP HLR5668W has mostly dark picture + grinding noise

Pix looks like a light pipe issue, inside the Light Engine. as far as the shutting down, could be a bad fan causing the grinding and when stopps the DMD turns the set off.
