1994 Eiki LC-5000 LCD Projector issues

[Captainclock]

Hello Everyone today a friend of mine gave me to work on a 1994 Eiki LC-5000 LCD Projector that has a hookup for a computer using a special splitter cable that is a parallel jack on the end that feeds the projector and standard VGA I/O jacks for the video signal from the computer (female VGA Jack for the computer/VGA In VGA Signal and a Male VGA Jack for the Monitor/VGA Out Signal) and anyways when I tried to feed a VGA Signal from my laptop to the Projector using the designated Computer input all I get is an image that looks almost like a TV with a badly adjusted Horizontal Hold and that's it, and I was thinking it might of been the cable (seeing as it looked like there was a package in the bag that this projector came in that was for a replacement computer video jack for this projector that was purchased in 1997 which was 3 years after this projector was purchased brand new which would indicate to me that possibly those computer video jacks that this projector used weren't the most reliable jacks which means this jack may very well of died as well) but I would like to see if anyone on here had any experience with this particular projector and might have an idea as to what's going on with this projector. The guy that gave me this projector to work on wanted me to see if I could get it going so that the youth group in our church could have a projector to hook their computers up to to show videos and stuff on during Sunday School and Wednesday night activities.

Any help would be appreciated.

Thanks,

Levi
