The projector has a RGB input
So to use it on a VGA output from the computer you would need a VGA to RGB adapter
or something like this adapter

with a component cable
as projector has component inputs also

the image is flicker, the light is twinkling, after seconds or minutes ,the projector power off.
1,the color starts to go out, it become the white and black,the image color is disappear.
2,then,the projector running off after only a few minutes,
it is a general issue:the inductor need to be cleaned
Use a cotton swab moistened with alcohol to clean the inductor.
the inductor (Sensing element),is near to the Color Wheel.
the industor : is a black little element,as little as 3 sesame seeds

how can I fix my flickering screen on my Hitachi DLP HDMI CP-DX250 projector

make sure you reset the lamp timer. Manual has the steps. Hitachi Performa CP RS55 3 LCD Projector

if the timer is reset, try cleaning the color wheel. Optoma HD20 Projector Cleaning this video is for an optoma but the color wheel is cleaned the same way in most DLP projectors. Dirty or dusty color wheel sensors cause the projector to shut down and act like its the lamp.

I have the same problem with a Hitachi CP-X345 Multimedia Projector. My Acer Aspire 3630 Laptop cannot be detected but it works without incident with a Dell Vostro 1500; just plug and play. Desktop settings to second screen doesn’t seem to help.

Hi there

Have you tried another cable ?

I have the same Hitachi CP-S860 and have found the problem is with the convergence on the left and right sides of the picture. The one I am working on has a bad ghosting problem also - you can really see the ghosting when the MENU is on the screen. The center convergence is OK. Following Pics show Circle / Cross pattern - 1st pic the red, green and blue are turned on - 2nd pic shows green and blue on only. I do not have the service manual for this set so I do not know the convergence procedure on this one. I have mostly been repairing NEC, Sanyo, Panasonic and Christie LCD & DLP Projectors.

Hello Dear,

This problem seems to be the main card problm which is connected with the RGB Panels of the Projector.
