Howdy,
Recently acquired a DK cab. The screen would scroll and dip and all sorts of messed up stuff.
So I ordered and installed the monitor and Audio amp board kits from bob roberts.
With that, it breathed new life into the monitor, colors are good, no more scrolling or folding. However, there are a few issues.
1. My screen still "waves" slightly(like the whole screen is on water), and also for example on the score, the numbers have a fast mini wave to them.
2. My B-Voltage only reads from 88.7 to 89.3. No matter how far I turn my adjuster.
3. When I'm playing the game, as the sound is going, it makes the screen jump or Beat, to every sound of the game. For example the music on first board, when it playes the lower beat especially, the screen will jump/bloom a bit. (is this the B-Voltage voltage not having enough? and no I don't have the sound too loud...lol)
So I'm not really sure where to go from here. Or what to order next. Don't get me wrong, the cap kit fixed 80% of the problem, but I would like to get it going as close to 100 as I could.
Thanks for any input!!
****Update**********
How on earth I missed Dokerts flow chart is beyond me. So basically I have to get a replacement for C606(value?)(for the wave. replace VR1 and VR2 on the game board, replace V352,353,354 on the monitor board for the jitters. AND I may have a bad flyback because I can't adjust over 90v......so Im I reading that right? (and does bob sell a flyback for this, as I don't see it listed under his flyback section)
Is there a chart or point me into the direction of a schematic that has the values of the VR(353 and so on) and C606 and such, as while I do enjoy buying stuff from Bob, his website is kind of hard to search items. And if there is anything else, I would need to order while I'm at it, as I hate this hen peck ordering. I would rather just order everything I need and get it all done.
Again, any help would be great!!
Thanks
