Cleaning dust ingress from the Sanyo PROxtraX PLC-XE31

[AngryTechnician]

After a recent exercise in the part-dismantling of one of our projectors, for which I could not find any disassembly guides online, I've posted a quick photo guide of getting the projector apart enough to clean out dust from the innards around the optical assembly.

I think these projectors (and similar ones) were fairly popular in UK schools when they were current models, so figured someone here might find this useful.

Yes that is not to bad a help sheet but it doesnt go far enough for most cleans, the optical engine needs dismantleing as well and the front silvred mirrors also need cleaning as they degrade the image.

BUT unless you are very competent i would not recomend any of this to be done by untrained users, if you move the polerising filters out of allignement you will lose blacks and contrast or worse.

 

This is DEFINATLY not an end user project unless you have projectors spare to practice on.

 

And is it worth doing it yourself what is your time worth and the risk of damaging a projector, as the normal cost for having this done is only £70

Well, it made a huge difference on mine even without removing the optics, and £70 vs. an hour of my time was definitely worth it.
