Haven't replaced my lamp yet. My original is pushing 9900 hours and still going. I have a replacement ready to go buy might try the bare bulb if I still have this projector for a 3rd lamp replacement.

So I replaced my bulb again after it hit 5k hrs and shut off. That was 2 weeks ago, I left on vacation before I replaced the lamp. Well I'm back home now and I replaced the bulb and reset the timer....and the picture just doesn't seem very bight. I've made sure all the settings are up so that I'm running in standard mode n everything but it just doesn't look bright at all. Its cloudy out today and the blinds are all down and closed and the wife n daughter both agree it doesn't look right.

Is there something I'm missing on doing after the timer hits 5k hrs and shuts down??

Where did you get the replacement lamp. Is it a genuine Mitsubishi lamp assembly? The new lamp may be defective or even a counterfeit. Some suppliers claim the 230 watt lamp for the 7800 is the same but the 7900 is supposed to be a 240 watt lamp. OSRAM P-VIP 240/0.8 E20.8 240 0.8 E20.8 is the correct bare bulb.

I would call them and say, the bulb you received from them is too dim fo a brand new bulb and ask them to send you a replacement for it.
