I’ve got a new astro city cabinet that i just got working after getting the chassis fixed. When i powered it on the horizontal size was almost 1.5x the width of the actual screen even when dialling down the H SIZE to a minimum on the control panel.
Ive double checked the cables on the chassis on the horizontal side and made sure its on “Narrow” rather than “Wide” and the connector for resolution is on the 15khz (printed as “low” on the chassis) rather than the 24khz (“high”)
Now a friend (who has more electronics knowledge than i do) suggested to either:-
1 - Change the horizontal coil on the chassis with one that has more windings (ie. more inductance) which will force the H SIZE to shrink a bit. Im not even too sure how to do that or where to get such a thing
2- Replace some of the ceramic capacitors on the horizontal deflection side of the chassis which will also physically shrink the H size too.
Am i missing something that I can do or tweak without having to do the above? I’m just afraid if i go with these approaches (giving that someone literally schools me on how to do it) i might damage something on the chassis or the tube.
Looking forward to the replies from the arcade professionals!
