thansk for the reply.

 

Yes the units are out of warranty, when you say optics do you mean the lens on the projector?

 

can you point me a link or place on showing how to clean it and or opening up the optics?

 

thanks

Sorry Im snowed under if you try searching for Cleaning projectors or the like it should pull up some threads if I get time later I will have a look.

 

I mean the internal light path rather than the the external lens, there are multiple small mirrors and lenses inside the projector. Under the top circuiit board there is a plastic moulding that holds the lenses / mirrors in place. If you cant take a laptop apart and put it back together without having screws left over then I would not attempt to clean it yourself unless you are willing to scrap the projector anyway.

 

If you do attemt it I would advise that you leave all of the lenses in place, if you put them back in wrong you will have a nightmare trying to figure out why the image is messed up, dont touch the mirrors at all the grease on your hands / harsh cleaners could damage them, just use somthing to blow the worst of the dust out. I would strongly advise you not to remove the prism if you do it will increase the chance of it all going pear shaped.

 

Dont take the projector apart until the lamp has cooled, dont work on it while it is live (i.e. unplug it), be aware that capacitors can hold charge (electrocute you) even if the projector is not plugged in, be careful of static - you could damage the electronics, be careful how you handle the lamp - take it out and store it safely while you work on the projector - they are under pressure and can explode.

 

If you still want to try then you need a nice clear working area and plenty of time a cam to take pics so you can remember where everything goes might be an idea as well.

If you need to ask how then i recomend you dont do it i spent a long time at Sanyo learning this trade, there are capacitors in there that stay charged for a long time after disconection and have several hundred volts on them, there are also static sensitive devices that even nylon socks would kill if touched by your finger unless you are very competent and electronicly aware then i would recomend you NOT to go inside, if you still decide to go ahead wear a static wriststrap and work on a rubber mat for both you and the projector bench (industry norm) and be very careful as told above not to touch any of the front silvred mirrors and take care NOT to move the polerising filters or you will lose true black.

Thanks guys, I will leave it as it is. Will eventually replace that project as that one is old, or perhaps get it cleaned sometime by Sanyo.
