IN72

Purchase Date; Aug 2006

Problem #1 Early 2008, PROBLEM SOLVED, I replaced this fuse THANKS TO THIS BOARD!!!! No problems since!

Today the projector smoked a lot and it will not work.

I use my projector EVERYDAY to edit videos on my computer.

Should I stick to a "home theater" model or get a business projector?

I want DO NOT need a better projector, it just needs to be reliable.

Should I consider a 700-800 SONY or MITSUBISHI? OR is infocus better in terms of reliability.

BTW, I run a fan next to my projector so it does not overheat because I using it for a few hours at a time. Do some projectors do a better job of not overheating?

If I spend $300 on a bulb will that fix the problem or will the projector fall apart within 1-2 years if I am using it everyday.

I TAKE THAT BACK

I close the projector and the LAMP WORKS, but it SMOKED UP AGAIN really bad!

to fix cost about 300-400 and when I need to get a lamb sometime soon this means it would be better to JUST get a NEW UNIT.

anyone else have a smoking unit?

My IN72 works just fine.
Sounds like you don't have a good air flow around the PJ.

Check out the the Mitsubishi HC1600.
At $650 after rebate and free bulb, it is worth giving it a shot.

It sounds like you have some serious issues with that projector. I don't suspect overheating, because there is a thermal safety switch on those projectors that will shut down if the temperature gets too hot. I have never seen a projector that smoked, could be component that is frying. Whatever it is, it isn't good and I would not use it until it was repaired.

I agree with Spectrumbx, Mitsubishi has some great (cheap) projectors. I've had mine for 18 months (the earlier version of the HC1600 that I would recommend to anyone today) and never had a problem with it.

And with the sealed optics, you don't have to worry about cleaning out air filters, it's a good, no-hassle projector.

I think you have a blown up capacitor on the power board. There was a post here some time back about it.
Edit: Found it. http://www.avsforum.com/avs-vb/showt...php?p=14285313

Just get a new unit. Popular is not necissarily the most reliable. For example the Grand Caravan.

BLOWNIN72,

How do you get at that capacitor? I bought a used unit and when I first turned it on it started smoking. Seems to be the same problems others have had, but unlike others, I'm so non-mechanical I can't figure out how to get at the circuit board. I've removed all the screws I could find but the unit's sides, which seem necessary to remove to get inside, won't pop off even with some major prying.

Anyone have instructions on disassembling or can point me to an online source?

Thanks --

Chris
