Question about BenQ PB6100 Multimedia Projector
Just replaced lamp thinking it was the problem but even with the new lamp, as soon as it gets warm, it starts buzzing.
If it is a high pitched whine, then it is most likely the color wheel. Mine did the same thing, took it apart and there is no way to lubricate the bearing, just have to deal with it. If it is a lower noise like a vibration or grinding, your best bet is to check the fans. Take the case apart and spin the fans to see if one is not spinning freely. You can lube them by taking the sticker off the back and putting a drop of oil on the shaft, then spin it until it frees up. Make sure you seal it back up with a piece of tape or something so that no contaminants get in there.
