Most projectors have air filters. Yours may need to be removed and cleaned. No air flow = overheat.

I have a Optoma EP721. It now projects verticle lines on the screen background. How do you eliminate the verticle lines ?


Hi,
It sounds like you have a projector which is in need of professional repair. You should eliminate source material problems first though by checking the projector with alternative input sources, ensuring that you also check the cables, and various inputs on the projector.
If the lines are present on all the inputs then the fault is internal to the projector. This will require professional repair. The first point of contact should be Optoma at www.optoma.co.uk/support.aspx (UK) or http://www.optomausa.com/ (USA). They should be able to give you an idea of ow much it may potentially cost to have your projector repaired and (most importantly) check whether it is under warranty. Most Optoma projectors ship with 3 year warranties these days.

My projector had a fan overheating problem. Took it to a repair shop. They opened it up and found that the blades were broken. They tried to get a new fan but Optoma refuse to supply them. Do you know...


I would look on farnell website.
you need to know the size and voltage, your repair shop can tell you that.
