My Galaga 88 has sound, but pic keeps scrolling.
the monitor is model 20-72AW






Here is a Video......


 
have you tried the V and H Holds? it definitely looks like it could use a cap kit too and if you need the cap kits or parts i have the best 100% nichicon 105c cap kits in stock for that monitor.

BTW: the h-hold pot is on the main pcb and the v-hold is on the 5 pot pcb on the back left of the monitor.

use my video to help you.

if that monitor has never been serviced, you need to get that done ASAP.

bad caps will cause your issue and when they fail you will not be able to adjust the issue again until it is fixed.

i can fix your monitor if you would like.

i have videos on how to remove your chassis from the frame so it does not so complicated.

i also sell the parts you need.

ok i tried the V hold and H

I kinda got it to stop scrolling. but still no clear picture .
I was checking the signal connection wires and noticed that the pins inside weren't making good contact So of course 1 of them i broke the pin inside.

What parts do i need to fix all pins ..








Also These 2 wire were hanging loosely do they belong plug into something ???

 
um. it's the 2 pots labeled V-Hold and H-Hold.
did you watch my video?

i have the parts you need for that header.

PM me and we can get you all fixed up.

the other 2 parts are for the speaker on the Sanyo.

i don't know if your particular game uses them since it is not Nintendo.

the Galaga 88 machine i saw once did not use them.

if you need the parts and the tools i have way over 150,000 pieces in stock on my site. i have open barrel crimpers which are way better then the crappy waldon crimpers that can easily be misused. let me know if you need the tools or the pins and connectors.
