Thank you very much for the replies fellas.
Yesterday I received a couple new messages from him, here the are:
It took me a while to figure out what Eco mode was. On my model there is an option to turn the lamp from STD to Bright. Consulting the manual clued me in when it said STD extended the lamp life to 130%. I waited for the projector to flicker before switching the setting. The immediate effect was that the flickering stopped. But after a few minutes of running in Bright mode, it started to flicker again. The flickering is more sporadic, but is not gone. Does that mean that the bulb is starting to go? Best Buy sent me a replacement bulb, but I did not want to put that in just yet since I am around 1800 hrs and even in bright mode, I should have around 200 left.
I suppose replacing the bulb is my next step to see if the problem persists. The funny thing is, while it was at Best Buy they had it running for at least 30 mins straight and it never flickered. Granted, after bringing it home and testing it out myself, the times to get the flickering to start varied. One test was around 10 minutes, while another time it didn't start for at least 45-60 mins. Before I replace the bulb, I want to call Best Buy to make sure that using the bulb doesn't infringe on the unit replacement policy.
I might have spoke to soon in my previous message. I turned everything off, and let it cool down. I fired it back up with the new settings from the get go and its been steady for at least 30 minutes. I'm gonna let it keep running until I Rampage beats Lyoto and see if it will keep going with no flickering.
Well, no luck. After about an hour it started to flicker again. That setting doesn't seem to fix the problem. So maybe it is in need of a new lamp?
I'm thinking about telling him it's the lamp, and to replace it, but he should check with BB policy first.
