Re: yellow hallo problem

It sounds like it is related to the red filtered glass before the prism inside the projector. When this gets to hot, it will burn a spot on the glass that causes the yellow spot. I have seen in happen on alot of epson 53c projectors. This has a red filter that is easily scratched when it gets too hot. It will actually look burnt.

There is no yellow colour in my emp 7600, can you help me how to solve this problem

Yellow light is made up of red and green light.
Your projector has 3 LCD panels. You need green and red to make yellow.
go into the menu and check that all the colour values are reset back to standard.

How do you hook up cable tv to my epson powerlite 830p lcd video projector

To hook up cable tv, you will need to have the cable running into a vcr 1st, then run either your s-video cable or audio video cables into the projector. Press the Source Search button on the remote control or the projector repeatedly until you see the image you want to project on the screen. The projector has two Source buttons.
Use the Computer/Component button to switch between equipment
connected to the Computer/Component ports.
Use the Video/S-Video button to switch between equipment
connected to the Video and S-Video ports.
? The remote control has four Source buttons. Use them to switch
between devices connected to the ports identified on each button.
(The PowerLite 830p does not support EasyMP.TM)
You can preview all sources on one screen to help you select the
desired source. (Allow a few seconds for the projector to sync up
after pressing the button.)

Yellow spots on the projected image

Hello there. First, some info you need...Green LCD=purple onscreen, Red LCD=cyan(baby blue) onscreen, and Blue LCD=yellow onscreen.
These spots (specks?) are probably dust particles that get past the filter. Annoying but harmless. To check if they are indeed dust bits, if you can focus sharply on them, then yes, its dust. To remove the particles completely will require a service. They will only return eventually. You can try to blow out the biggest offenders with some canned air. And, to help slow down dust entry, keep the dust filter cleaned so that the unit always has plenty of air movement--you'll have a cleaner image with the added benefit of LONGER life of the lamp and projector components (dust is the number 1 killer of projectors)

LCD projector spots showing up on the screen

there are light filters behind each lcd panel that determine the color of light going through it. because of excessive heat and dust, the filter tends to burn and cause discoloration in the image. if the image is bluish (cyan), the red filter is burning. if it's yellow, the blue is burning. if it's purplish (magenta), the green is burning. the filters will need to be replaced. unfortunately, many companies don't sell individual parts of the optical engine, so the entire engine might need to be replaced.

Yellow green screen


If you are connecting it to a computer with a VGA cable, you may have to go into the options of the projector and set the port correctly.

Go into the menu, and select the "image" area. In here you should be able to select computer.
