right, i have a panny ae200, projecting onto a 70" 16.9 diy (blackout lining fixed to a frame) screen. it has roughly done 350 hrs in 8 months, which works out as roughly 525 hrs a year at the rate i am using it. also i would like to use it more for playing games etc... but i keep on worrying that the bulb will go prematurally. would there be a huge difference in brightness & contrast if i had a proper screen, as i am happy with the whites but blacks are more drk green/grey. just wondered if blacks would be more black with a proper screen ? also what is the optimum amount of time the pj should be left on for ? i tend to watch 1 movie at a time so it is usually on for 2-3 hours at a time, but after reading calibos thread he managed to get the 5000 hrs out of his panny ae*00 and he used it for roughly 6-8 hrs at a time. so which is better keeping the pj on for longer per use, or shorter per use ? also if the electric trips while the pj is on does this do much damage to pj lamp life ? my son once turned the plug switch off whilst it was on but i quickly flicked the switch back on and the pj came back on with no lamp lit just fan spinning fast , but then 30 seconds or so later the lamp kicked in . so i assume the panny has a safety feature which cools the lamp if switched off improperly ?
