those ali light covers are better than nothing, but be warned they're not OEM. They basically are cheap, brittle plastic that has fitment issues. I ordered 2 before and they sent me like 5. I can't say whether or not the light boards work the same but they're probably better pcb clones than the...

super bikes is a pc. it outputs audio from the motherboard audio plug over a standard audio cable. It then goes into an io board where it gets amplified and then to speakers. you intercept it directly out of the pc motherboard.

I got the kind that has a headphone jack, it comes with a short double ended male cable so it just plugs in directly with no splicing.

Another Repair Log: I was working on one Pinnacle today that kept resetting the saved settings. It was as if it was doing a factory reset every time. This one was a black, rear left prize chute. First thing I noticed was when I checked the ROM was it was fine and the same checksum as a front...

There's another thread on the NT-550dx that I think we figured out that one of the knobs is B+ adjustment? I am not sure I am remembering correctly https://forums.arcade-museum.com/threads/neotech-nt-550dx-manual-and-schematic-needed.515427/ I don't know about the yoke board, I don't recognize...

There is a calibration knob. Use a known good meter to get it dialed in.

I had one of my nicktoons nitro monitors go down with a partial vertical collapse. I pulled the chassis and I was going to just do a cap kit and see if that fixed anything but I also noticed that IC401 next to the flyback was completely burnt up. I looked at my other nicktoons nitro next to it...

I couldn't find that W1 jumper after looking for it on the PCB. That diagram is a lot clearer than the one in the drawings I had, but still... I could find 4E and 5B, but not W1. I'm working on a defender, but joust was in the video that led me to my fix... 2E and 2M on defender were the...

after cross referencing Ron's video here I see that the screen control is related to some 74LS257 chips on Joust. I looked up where they are on Defender and it's a similar setup but different locations. There was one at 2E and one at 2M. I first messed with the one at 2E and it kind of helped...

Hey guys, I'm working on bringing back a Defender PCB set. I've got a fully working cabinet and multiple extra boards that I'm working to get another set out of. The main pcb I have the furthest along is "playable" as in it reports all initial tests ok. It doesn't seem to crash, but there is an...

So you have the 3 VR style. One is for initial grab strength, two is rising claw strength, three is carry home strength. You can adjust them blindly or go into the setting mode with the switch on the coin mech.

The play till you win setting is done through dip switches. Do you have the kind with 1 VR or 3? Take some pictures of your PCB or the volt meter? If you have the original roll down coin mechs they have a small switch on the back of them? you use those to go into the voltage adjust mode. DM me...

My PP won't shift into high gear anymore. If I test it manually it does register. However in gameplay the knob isn't working?! I'm serious guys, help me.

it's been a while since i did this... from memory though you need to burn the new boot roms which don't have the security check.

This is the only place on the internet this information currently exists afaik. The NT-500DX is a different chassis with different values and position numbers for the caps. I have 3 of these Nicktoons Nitro games and they have the NT-550DX monitors in them. I think it's SVGA? Either way they're...

I replaced all of the electrolytic capacitors on the chassis and now the picture is working on boot as expected. It also cleared up some other minor issues. Improved color and geometry. Should I just post the cap list here or is there a more official repository?

Noticed two little access points. I’ve never seen this style before. TP1 and J2 seem to be the only ones that I see? I would prefer something I can clip onto, but I think I could make them work if I had to.

I don't really want to do any unnecessary surgeries on something that is on my route. You said yours is broken so what if I break mine... I also don't know for sure that is the fix for yours, like @Ohmerone said it should still work without it to some degree. Here is a picture of the bottom of...

I already pulled the chassis out of the cab and took the caps off of the chassis to make a cap list. And I already ordered the caps from digi key. I got 21 different values, matching the ones I pulled from the board. Yes there are probably mostly still good caps, but they are SAMXON. The problem...
