About 16 months old 1818 on the bulb all in low lamp so I expect a fair bit more life in it yet, used it last night all fine. Switched it on today and the picture was really dark and faint, gave the lens a clean but did nothing, try another source (white background) but it was all faint again like the contrast was out. Cue panics of £250 for a new bulb or worse a faulty machine (it was a grey import) Obviously I checked all the settings but nothing had to changed. Only thing I could think of was possibly condensation inside the unit (we get a lot on the window). I took the unit apart and blasted everywhere with compressed air, crossed my fingers restarted it and it worked fine. Could my condensation theory be right or is there a possible other cause someone could shed some light on?
