theres another fan next to the engine. all fans must work for the lamp to light. the colorwheel must be turning freely for the lamp to light. you can also take the top cover off and then slide the lamp out and then back in while watching to see if the connection on the lamp is pushing the female part on the lamp housing back instead of going into it. if it is, hold the female part in place with a driver or something while pushing the lamp into it.
I would expect the Power Supply is ruined, and maybe even the entire unit has been damaged. Look with Power Spikes, you can often get Insurance coverage for this event. You need to take it to a reputable repair place and if they agree that it has suffered a Power Surge/Strike, they write a report and you can claim insurance. I write reports like this for customers quite a bit.
you can check the fuses (located on the power supply board where the cord plugs in), but it's more likely that the caps are dried out and need replacing, or the whole board itself. if that's the case, try av solutions in ny. they're an infocus service center and they're really good. www.avsolutionsny.com
Please describe the status of the LED indicator. No LED would indicate a failure of the power supply. I can help you with that.
Flashing red would indicate a fan/lamp problem. Some lamps fail prematurely before the lamp hours are up.
If it is the power supply, no lights at all, I can get you running again. These units have fragile power supplies that can burn out with the slightest power surge. A UPS goes a long way to save future headaches.
You should get some indication of power even without the globe. This can however be a problem relating to the globe not being inside the projector.
Most projectors use a switch inside so they know when a lamp is installed. Some have several of these and a fuse that is on the lamp unit itself.
Replace the lamp back into the projector and apply power again. If you get lights then you have that much solved at least.
If there are still no power lights at all, then you may have had a power surge that not only killed the globe, but has blown the internal fuse for the power supply as well (or even killed the power supply)
To get access to the power supply you will need to disassemble the whole unit almost. If your not comfortable doing this, then I would advise getting it checked over by your local tech. It could save you hundreds of dollars buying a new lamp when the projector may not be worth repairing.
FOr most service centers, the only available parts are the modules themselves. There are very few of us left that actually perform component level repairs. In the case of this type of unit, there are no component level parts available as the only "parts" supplied by LG are modules. Dep[ending upon the servicer's experience and the nature of the problem, it is possible that the module could be repaired. This would not be an "authorized" repair, but it is possible. What is the nature of the problem that warrants the requirement of the motherboard?
