HLR4667 screen goes "blank" or freezes...

[AT1984]

I have a Samsung HLR4667WAX. Bought it in August 2006. The Color Wheel was replaced under warranty in January 2008. I replaced the projector lamp (3rd one) in August 2011. It has always worked great, until a few days ago.

The TV will turn on, and the picture is great...after 2 or 3 minutes, the screen will go blank (or "freeze", sometimes), then come back on. The sound goes out when this happens. The screen doesn't go completely "black", you can tell the lamp is still on. When all this happens, the Timer light on the power button will flash. There is a slight "buzzing" sound from the TV, but that was there, even before this started.

There is no "clicking" sound, like the ballast, when this happens.

This happens every 1-2 minutes.

Any ideas?

Thanks in advance!

Wow...(insert sarcasm)These forums used to be a wealth of information. Now, I can't get ONE reply or idea after 48 hours?

If I just had to replace the lamp, I'd have 30 replies!
