Replaced lamp without touching anything else.Picture was unclear. I turned of and saw (after everything was cold) by coincidence that lamp was not correct mounted in lamphouse (around 2 mm wrong at top - Ok at bottom). Now it won't start again. Indicator on top says replace lamp with green colour - but lamp is definately OK. Are there any "overheating" control procedure or anything else that has to be "set-to-zero" or similair...before starting up?Please help - just now looking TV on pc :-(

It's very unlikely that this is a due to a faulty bulb.
It's possible that there is a fault with the projector which existed before you relamped it, (i don't know the exact circumstances) but you could try the following steps
1) If the old lamps still works, remove the new one and replace it with the old one. fire the projector up and see what happens. If nothing happens replace the new one again, making sure you don't touch any glass parts (as it can shorten lamp life) or any other internal parts.
2) Turn the projector on and check the image with different picture sources and cables to rule out a fault there. Is the image distorted while the projectors warms up and displays the startup screen? If the image looks correct the problems is likely to be outwith the projector. If the startup image is distorted then the problem is likely to be with the projector.
You should ensure that the lens is free from obstructions. It won't make much difference in most instances but you could clean it with a soft cloth, taking care not to damage it.
Hopefully these steps will help you fix the problem.
It must be overheating problem . Check the fans . If the fans run properly , then you need to check the fuse or the power PCB [printed circuit board ] . If everything is okay with all of those , then I recommend you to replace the bulb .
Here I'll tell you how to replace it :
Make sure that your power switch is off and that the power cord is unplugged from the electrical socket. It is also wise to unplug any other cables and label them in order to restore them in the right way once the lamp is replaced.
In order to see the lamp, remove the access handle on the outside cover. You may need to use a screwdriver.
Pull out the used lamp and clean the relevant parts using micro fiber products and not paper. Please note that in some projectors a small inside filter should also be replaced.
Insert the new lamp into the projector carefully avoiding touching the glass of the lamp itself. Touching the lamp will deposit skin oil that will likely damage any new lamp during use.
Reassemble the access panel, repluge the cables and power up the projector.
If I remember correctly, you hold down either the power or the menu button for 30 seconds... I believe it is the power button, and it will briefly display it on the screen, but this assumes it was reset at the time the lamp was installed. The counter counts up on this model, and the lamp replace light will come on at 3000 hours. I have 2 of these units, and I have gotten at least 5000 hours out of each lamp. Toward the end of the lamp life, it may start getting dim and/or have difficulty starting, but I probably wouldn't replace it until you either notice the dimming or the lamp fails, although I've heard some say they can damage the projector when they fail, I have not had any problems.
the reason that it turns on without hitting the power button is that it thinks it's still in cooldown mode. while it's on, check the lamp hours through the menu. if it's close to 2000 hours (or the inside of the lamp is blackened or bulging), replace it. after market lamps never seem to last that long. if the fans stay on when the lamp goes off, it could also be the colorwheel. listen for chirping. if it chirps, it's the colorwheel.
If the lamp is working it should be fairly obvious but stand to one side of the lens and see whether there is any light coming from the projector. If there is you know that it's an input problem. If there isn't either a fuse has gone, the bulb has blown or the filters might need cleaning. If the bulb has blown it's probably because you handled the bulb. It's vital not to touch these bulbs with your fingers. If you do wipe it with methylated spirits.
Hello! Lamp or ballast(if lamp has been replaced) is bad. Explanation: green comes on: system works, waiting for light to shine into light engine: no light is coming out of lamp, system shuts down, then you see red! how to determine: pull the lamp out of the unit's compartment. Inspect lamp: bloated stem? shuttered? reflector is not shiny? Chuck it! Lamp looks good or just been replaced: try ballast. Close lamp compartment without lamp itself. Make sure, door is shut, as well. Turn unit on and listen close to lamp compartment: good ballast will make a buzzing noise, then stop. You've got "red'! No buzzing: ballast quit. Needs major repair! Lamp must be good, for sure, to get to the last part of diagnostics. Conclusion: more, than 2000 hours of usage: replace lamp first! Good luck, Alex.
Either the lamp needs to be replaced, or your projector is experiencing overheating problems. The unit may not be running hot but there may be a bimetal thermal switch that has become fussy. If you have an electronics supply nearby, they will have 'freeze spray' and if you procure it, you can see if the projector will turn back on if you give it a shot in a vent. Do NOT spray it on a hot lamp; it may cause it to fracture. If this does make it turn back on, you will have to locate the failing switch although the common ones are disc-shaped with two contacts coming from them.
