Quoted from johnstewart:
This is a big post about my current booting woes and related issues; I will try to break it up with titles for the various sub-topics to make it more clear and break up the wall of text.
My electrical engineer friend suggested these as a high quality capacitor for the job; I bought them, he replaced the 5x caps noted as unreliable (though they looked to be in fine shape physically):
The good news is that it was a successful capacitor surgery... it works. The bad news is my game is no better. It still doesn't come up on power on, but takes 15-20 minutes to come up. Then (knock wood) it plays fine.
I thought power seemed to be good; it looks to be a newer power supply and when I tested, it had slightly over 5 or 12 volts on most pins.
There was at least one pin that wasn't exactly around 5 or 12... but I assume that was intentional(??). I'm not finding anything in the manuals referencing the voltage on pins.
This is the PS, it looks like this is actually the model I have: amazon.com link » so a newish one. It seems unlikely to have gone kaput so soon, but I guess it's a cheap thing to swap, I may try that now that I know it's not the capacitors.
What are people doing for power supplies on Pin2k's? Looks like you can jumper an ATX style power supply, which I think would be more reliable/efficient/modern, no?
I tried pulling it to see if it would boot without the PRISM card in place; this didn't make any difference.
I did notice when pulling the motherboard to do the cap swap that there is a dangling cable off the power supply to the PRISM card that I don't *think* was ever plugged in.
Does everyone have this, and should it be plugged in somewhere?
As far as debugging this, it would be helpful to be able to do it with a monitor outside of the pinball machine. I've got some other LCDs I can plug in. What's the best way to get output at a "normal" refresh rate?
Is this card best for the job?
@applejuice this is you, right? The link to the details page is not coming up right now (https://mypinballs.com/electronics/cga_sync_adapter.jsp), FYI.
One of the problems with mine, after being on route for a long time, is the main shot up the middle doesn't register well. It looked like the switch got bent out of shape (literally) from taking a beating. I tried to bend the leaves of the switch and it seemed better for a bit, but now it's not registering hits much again. Is there a good guide on how to adjust these somewhere? Or, would it be best to just replace it?
@sonic these are your creation?
These "MRS"es are switches that detect the ball traveling over it?
I have seen your mention of these... but I didn't see in the thread any info as to they're actually used on the game; I'd like to check mine to see if they're still good. Where in RFM are they used? And are making more soon?
Thank you all for your help!
