Hi all. I've got a neo geo 2-slot that I wanna possibly use as a multigame. But before I do that, I need to get the monitor working.
Here's the workflow I've seen so far.
1. Monitor wouldn't power up at all.
SOLUTION: DMM told me that the iso transformer wasn't outputting power, turned out that the neo geo power supply wasn't working for the 120 out to iso. Replaced fuse on power supply, got that part up and running again.
2. Monitor powers up, hear neck chatter and see neck glow. Doesn't look right at all. I decide to do a cap kit (ordered from bob roberts).
Attached picture is what it looks like with cap kit.
(yes, the board has problems too, but I'm not so worried about that, as I'll be replacing that anyway, I just wanted to see the rom error screen)
3. Checked the HOT on the chassis. I get a reading of something between .500 and .600, so I'm assuming the HOT is good.
Anyone have any ideas on what this could be? I'm a total monitor n00b, and this monitor doesn't have any kind of flowchart to follow.
Some other notations:
- It's hard to keep the Horizonal Hold fixed. I can move the pot, but it doesn't really stay fixed in one place. Same for vertical hold.
- The size is quite large. The backup ram error is a rectangular box centered on the screen (as seen on my test bench). The picture here is huge!
Thanks for any help!
Steven
