Yesterday, I noticed that my HLP6163 started flickering a lot with colors totally off. I tried switching video inputs and I kept getting the same thing. So I turned it off, let it sit for about a half hour, and then turned it back on. I got sound but no video as the tv cycled through 3 times automatically of turning it off and on, and on each attempt I could hear the fan (or at least that’s what I think it is) struggle to turn on properly, until finally I got the dreaded 3 blinking lights. I turned it off again, only this time by pulling out the power cord as well. This morning, I plugged it back in, turned it on, and the tv cycled 3 times just like yesterday, but the faint fan noise was now a loud, distinct humm that pitched up and down. I have no idea what’s wrong. I suspect it to be the lamp, but I just got a new one put in on 8/17/07 (BP9600826A from samsungparts.com) and I’ve never heard of this loud humming noise before. From reading the posts, maybe I need to get a new fan or colorwheel as well?
