Question about InFocus ScreenPlay 4805 Multimedia Projector

2 Answers

Projector Problems I bought the InFocus Screenplay 4805 about 2 years ago. It has been a great unit until recently I went to turn it on and nothing happened. No lights, no noise, nothing. I tried plugging it in to another outlet that I new worked and still nothing. I opened the case up and noticed a ceramic fuse. Is there a way to test the fuse to see if it is blown? It is also removable and the number on it is t5a250v. Should I pursue changing the fuse or do you think there is a nother fix? RadioShack was no help and I have not been able to find it on the net. Please help

You must replace the lamp. If the lamp is not fired nothing else works. Their lamp runs for 700 hrs max based on my experience. That was about 2 years of usage for me and after I replaced the lamp everything worked

Sounds like the fuse popped. t5a=5 amps 250v=250 volts So you will need a fast-acting 5 amp 250 volt fuse

Infocus 4805 Light Tunnel DIY Replacement Option

About a year ago my light tunnel failed and I was able to fix it thanks to info on the net. Then about a month ago I decided to try to finally replace my Light Tunnel. Mainly because replacement parts are discontinued and manufacturer repair is way too expensive. In the process of failing, I was able to find a great low cost solution that's pretty easy to fabricate. My post is here:

If you have never opened your Projector go here:

It's regarding Dust Blobs, but it has pics to show how to disassemble the unit.


So as for the Tunnel and getting to it...here is a thread for a different model PJ, but the layout is very similar:

Hope this post is helpful to you :)

Projector stays on for 3 minutes then turns itself off

Hi Chipped Rice

The loud buzzing noise you heard was the colourwheel that gave in.

Now what happens is , the machine will turn on and go through the whole cycle and as soon as the colourwheel is supposed to start doing it's stuff the Projector will switch off because there is no response from the coulourwheel itself.

You will have to replace the colourwheel unfortunately as it cannot be fixed.

Thanks for using Fixya !
