Question about Samsung HL-R4667W Rear Projection Television
My Samsung HL-R4667W DLP TV has 5 verticle, mostly green lines on all digitle channels, but all HD channels pictures are fine. I know by testing, the cable to TV is fine. Would like to fix myself.
I just called customer support and my issue is now fixed, to my extreme surprise.
It sounds silly (and a tad embarrassing), but here's what I did:
1) Unplug the TV
2) Wait 30s
3) Plug the TV in
Apparently even if the TV is "off" for a few days it never fully shuts down unless the power is unplugged. Not sure if this will help anyone else, but I had the exact same problem others are describing. Good luck!

I am having the same problem. It was diagnosed as a failed optical block (optical engine/light engine). It isn't the lamp seeing as there is a variance with the different signals. If yours happens to sound like a squeeky fan it could be a problem with the color wheel... though it sounds identical to mine so I highly doubt it.
Sony and Mitsubishi have had the same problems with the technology and will sometimes take care of repairs out of warranty. Its essentially a failure with the technology--they don't even make them like this anymore. Unfortunately the repair is around the price of a new TV. Given the failures try talking to Samsung (1-800- SAMSUNG). I purchased the TV from a warehouse store so I am in the process of trying to get it exchanged.

Tweetie57 - If you're getting good picture on HD, then it's very likely not the lamp. I have the same problem, only non-HD pictures are affected though. The menus and PIP and HD signals look fine. I'm pretty sure that's a digital board problem.
