Blow out any dust with canned air. chances are there is an object blocking the image. or there is a crack or burn spot on the 2nd fly-eye lens (diffuser). the first one is right next to the lamp (if you remove the lamp, you'll see it). the second is right on the other side of it.

After my vp800 plays for a hours it cuts off. WHY?


Remove the cover and check whether the air filters blocked with dust.
Whenair filters are blocked, air doesn't flow freely through the projector. This result in overheating, leading to automatic shutdown.

I have a Sony lcd data projector- VPL-SC50.. There is a big black blob in the middle, with other lines near the edges. And the blob is growing larger now. But it does not look like a burn out, it looks...


Normally a "blob" on an LCD is a delamination of one or more of the LCD panels. But, they are usually not black. You may have a poor ribbon cable connection from the main board to the LCD panels....there is a ribbon connection to each of the Red, Green and Blue panels. It's either that or a main board failure, but certainly soemthing you want the factory or other authorized service center to check out.

Good luck.

remove the rear cover then the top and look to where the lcd cables go down from the main board to the lcd panels. move the cable 1 at a time towards the connection on the main board just so you can see down into the panel and give it a good blast. de-ionized air works best. repeat for the other 2 panels.

You don't probably, your laptop screen is not exactly becoming magnified, the resolution is being lowered to match the maximum resolution of your projector which is only 800x600. They are setup as "cloned" together. You could try setting up an "extended desktop" rather than having the projector "cloned" with your laptop screen, that way you can change the resolution (within their allowed limits) of both displays independently. To do this, Right click on desktop and select video setting or the control panel of whatever video card you have. If you can set up an extended desktop, it is here that you'll be able to do it.

Can't get computer images to project


Hi, I have found out that you must have the laptop set to an external monitor, in the control panel, display area, click on 2, then you must have the projector turned on before you start the laptop so it can recognize that the projector is there. Also make certain that you allow the unit to cool off by turning the lamp off, leaving the fan on and open the door where the projection lens is located.

Color problem


Hi christisfree

Try using a different cable that you connect from your source to the Projector.

A colour change is normally a faulty cable , but if the problem persists after changing the cable , then you might be in for a new Mainboard.

Try the cable and get back to me on this one.
