Title: Wells Gardner K4600 line shift in screen - HELP Pleeeeaase
Post by: tjc02002 on August 24, 2011, 04:33:16 PM
Hey guys. I am new to the Arcade Machine collecting hobby and I have a slight problem with my Wells Gardner K4675 / K4600 series 19" monitor. It has a couple of lines on the very left edge (considered top of monitor since its mounted vertically in my Frogger cabinet). I have attached a pic of the problem. It looks like basically there is a couple of lines on the very left edge that are not oriented correctly and they are deviated into the picture a little, and it leaves a black line where the line is missing. I have spun all the adjustment knobs and it doesnt help. Screen control doesnt fix it...

Background: I had some color problems and hourglassing along with this line problem so I did a "Cap Kit" on the monitor and reflowed any suspect solder joints. This fixed all the hourglassing and color problems but didnt fix this line error. Another thing that is weird is that the image is shifted left a bit even after I moved the vertical raster position jumper. It seems that the image cant get quite to the center of the screen. Another thing to mention is that the cap kit had about 20 capacitors, but it seemed to me that there were a couple of them that were not replaced.

Any info would be great. Thanks!

C315, C201, and C202 were not included in my cap kit so i didnt replace them. Could it be those ones?

C315 has a jumper across it, is that supposed to be that way? BTW, Im running a 60 in 1 multicade game board.

Pretty much fixed it. It was a loose connection/solder joint.
