Title: double image on WG4600??
Post by: brandon on October 08, 2002, 11:17:55 pm
just wondering if anybody here has any experience with the WG 4600 series monitors...  Mine is giving me a double image for some reason..   Im driving it with a Jamma PCB not a computer so it should be able to display the image.  The double image is vertical and overlapping in the middle.  Other than that the picture is perfectly stable. no rolling or anything.
I simulated the effect in Paint Shop.
BTW, it vertically mounted but I rotated to pic for lack of confussion

If it is vertically mounted but the picture is rotated back to horiz to show what is happening then it looks like your horizontal hold is not adjusted.  Could it be as simple as that?

Well, I adjusted all that and the picture stopped rolling but I still get the double (sometimes triple) image..  Maybe I have a fault monitor?  but I've never seen one do this before...

I am confused due to the rotation.  I probably meant vertical hold.  But you say you adjusted it to stable but with a the double image.  Maybe a sync problem?   Here is a flow chart link you probably already have.

There is a small note re jumpers and sync that I am not familiar with.

Ok after removing the H/V board and cleaning and resoldering a few question areas, cutting the bypass jumper on C315 and also tweaking every knob that had anything to do with vertical (and a lot that didnt)  I finally got the double image to go away..... now I've got a nice pin cushion image that a cap kit should fix  ;D  Thanks for your help guys! ;D
