OMG What have I gotten mysefl into! 8 additional cabs in one shot...

So I went to the bank today to cash in the quarters I found in the cash boxes.

*drumroll...................*


$190!! SWEET! That should more than cover the cost of most of the small parts I need to get like bulbs, locks, cap kits, etc. Even a few switching power supplies and possibly a game PCB will fit in that budget, if I'm careful. :D
 
If you end up scrapping the neo geo / wow, let me know. I've been looking all over for one of those front trim pieces.
 
IF you want to sell that pacman monitor glass i would be interested.That is if you are palnning on putting a ms pacman in its place.
 
Thanks for the heads up -- I will ask the owner if he wants to buy the proper bezel glass. It will be helpful for him to know that we have an interested buyer for the old bezel.
 
I learned a valuable lesson tonight, which I will share in a bit.

So I was perplexed by the whole Mortal Kombat 'shut down' phenomenon. Since I haven't figured out why it's acting the way it is, I figured I'd swap the monitor (a G07) with the monitor that was in the Arkanoid cab. I knew the monitor in the Mortal Kombat cabinet worked, so that would rule out the possibility of a problem with the Arkanoid monitor.

When I put the monitor in the Arkanoid cab, I got the same result: game played nearly blind, red color only, inability to stabilize the picture. At this point I suspected either the power supply was bad or the PCB was hosed. Just for kicks I plugged one of my spare Double Dragon boards into the jamma connector in the Arkanoid cab. Bam, perfect picture, and the game coined up and started properly. So, the power supply is good. That left the PCB. Remembering the problems I had with an older Double Dragon PCB jamma connection causing issues, I decided to examine the jamma connector and harness.

I should have started there to begin with.

Voila! Re-seating the jamma harness and cleaning the jamma connector contacts was enough to get this game going again. So, valuable lesson learned is: start with the simple stuff first before you go doing things like removing monitors :scratchchin:
 
Make that 9 cabs!

On a whim, I picked this up:

It's an Operation Wolf cab converted to Golden Tee.

The flyback is hosed on the monitor, otherwise the game plays blind.

Make that 9 cabs to work on :D
 
Ms Pac Man -- something smells funny here....

Thanks, everyone, for the kind words of encouragement. It helps a TON when you guys pipe up and cheer me on. Feels like I have an audience that actually cares what I'm doing.

A lot of what I'm undertaking will be things I'm doing for the first or second time. I've replaced capacitors before, but I've never recapped an arcade monitor. I've tinkered with arcade cabinet mechanical parts before, but never really worked on replacing or servicing things like leg levelers, interlock switches, jamma harnesses, switching power supplies, ground cables, marquee lights, coin mechs, volume potentiometers, etc.

Speaking of coin mechs, I dug into the coin mechs on the Ms Pac Man cabinet last night. Owner told me that one side didn't work (and so he taped it off with electrical tape), and the other side seemed to only work 1/2 of the time. The other 1/2 of the time, the quarters just fell into the cabinet and not the coin box. I opened up the coin mech door, and here's what I found:

index.php


Yes, folks, your eyes are not fooling you that a TOILET PAPER ROLL TUBE scotch taped to the inside of the coin mech opening!!! LOLOLOLOLOLOL I've seen some jerry-rigged things before, but this one comes close to the best yet. And this is supposed to be a 'restored' Ms Pac Man cab, too.

Needless to say, I ripped out the poop paper roll solution, and fitted 2 coin mechs from the Neo Geo (Wizard of Wor) cab. A shot of WD-40 and 10 min later Ms Pac Man has 100% fully working coin mechs. Now I just need to cap the monitor, and she's done.
 
The dreaded WG 19K7302 and Neo Geo partial success

Emboldened by my success at getting the Arkanoid cab up and running, I decided to look at the Neo Geo Cab and see if I could figure out why it wouldn't power up. The monitor in it, a Wells Gardner 19K7302 has a manufacture date of 1997, clearly the newest of the bunch here, so I was betting that it would perform pretty well in my Golden Tee 99 cab as a drop-in swap. I soon learned later that it wasn't. Read on....

I pulled the monitor and moved it to a table next to my Golden Tee cab. Since both are Wells Gardner monitors, the pinouts for RGB, ground, and sync were similar, so the connectors fit without any modifications.

I powered on the Golden Tee and nothing. Game still plays blind, monitor shows nothing. Tweaking the settings on the remote board did nothing. I can see a little bit of neck glow, but my untrained eyes cannot tell if it's not enough neck glow or not. Damn, and I thought this monitor was going to look good. So, back into the Neo Geo cab it goes. I guess I'll have to see if I can at least get the PCB on the Neo Geo cab to fire up, and I'll address this monitor later, when I have more time to read about it.

The back end of the Neo Geo cab was a mess of tangled wires, some tight, some loose. Whomever converted this from Wizard of Wor to Neo Geo cut some corners, because none of the interlocks are used any more, the power switch has been bypassed, and several wires from the jamma harness are just spiderwebbed everywhere. It looked like this cab had been rolled down a hill somewhere.

There were 2 power supplies in it, one older, and one newer. I presume the older one died at some point, and the operator never bothered to remove it. Instead, they just fitted another one in the cab and just laid it on top of the old one. Not screwed down, not secured in any way. Just flopping around in the cab. :(

The power cord coming out of the back had about a 6 inch length of cord that had been spliced together. I'm guessing that's where the cord had originally gone to the power switch, and then from there to the isolation transformer, but someone just bypassed the power switch altogether and wire tied the cord in one length. Rather than go through the hassle of hooking up the back switch again -- really, at this point, why bother?? -- I decided to tie a knot in the cord downstream from the splice and left everything inside the bottom, coming out the cord hole. The knot will provide the proper strain release necessary to ensure that no one pulls the cord apart.

Examining the plug at the other end revealed why the cab wouldn't power on. After removing what seemed like 14 miles of duct tape wound around the plug end, I discovered that the plug fixture was loose. Taking apart, I found the ground wired to one of the hot/neutral contacts, the hot wired to the other, and the neutral wired to nothing. Hm....that's not right. Good thing I was using a breaker protected power strip when I plugged THAT cab in 2 days ago. *eek!*

I wired up the plug correctly, did a smoke test. I heard the familiar 'bah dah da DING' of the Neo Geo start sequence, and the marquee lit up! Woo Hoo! It works!

The monitor shows an image, but it's VERY faint, and I can see almost no color. Adjusting the controls on the remote board works, but since the image is so faint, it's hard to tell what's going on. What's wrong with this stupid monitor? Does it need a cap kit? Flyback? Sledge hammer? The chassis looks nice and clean, and the screen shows ZERO burn. Shame this won't work.

The PCB goes through the start sequence, and then it starts to get loud and scratchy when the game starts to load League Bowling. Then the game restarts. Is it possible that my Neo Geo cartridge is bad? The owner says he has a few more cartridges in his garage somewhere, but he couldn't find them. I'd sure like to try another one to see if that's the problem.

Anyway, that's where I'm at for now. At least I know that the Neo Geo cab might be salvageable. The monitor, however worries me. I really can't find anything out there about it -- it's like WG didn't make them. The serial number doesn't come up on their website lookup, and I can't find a manual or schematics anywhere. Anyone have any other ideas? Should I just forget about it? Can I put a different chassis on it?

Or get a monitor extension cord so you can plug the game into another monitor without swapping.

I've heard of those. Anyone have a spare they would like to share?

Or I suppose I could make one -- I have enough parts floating around now. The power part seems straightforward enough -- hot, neutral, ground. How would I do the signal part? It seems like each type of chassis has it's own type of plug, pinout, and some have an inline row of pins, whereas some have 1 header of pins for RGB-ground-sync, and one header of pins for more ground and sync connections. Is there some sort of 'universal' approach I can take? Anyone come up with something that works?
 
Damn, I hit a road block on 1 of my monitors.

It's a WG 19K7602. This one came out of the Golden Tee cab. Right after I took the monitor out, I could tell that the flyback was blown, so I ordered a replacement from Bob Roberts. I was all set to go at my soldering bench when:

index.php


In this picture you can clearly see the blown flyback, but you can ALSO see something that doesn't look right. I circled it in red. It appears that someone has installed some components to either bypass something, or jumper a connection. Either way, it doesn't belong I don't think?

Then I turned the board over and it just got worse:

index.php


Wow, that's ugly. I don't even think it's worth trying to recap this board and/or replace the flyback. There's no way I'd feel comfortable putting power back to this chassis again. Does anyone have a spare chassis that will work for a 19K7602 I can have/buy?

Grrr........ :mad2:

holy crap!! thats just plain scary!
 
Lots to share today...I spend several hours in the shop / garage last night.

I finished and sent out the Ms Pac Man cab last night -- the owner was very happy to have a nice looking screen again, as well as working coin mechs. I very much wanted to ask him who the toilet paper roll engineer was, but I bit my tongue :p I ended up pulling the Electrohome G07 out of the Mortal Kombat cab and using it in the Ms Pac. The monitor that I pulled out of Ms Pac needs a cap kit that hasn't arrived yet (ordered yesterday from Bob Roberts), but I wanted to get this cab back to the pizzeria ASAP. There's a big town festival this weekend (Wheels and Wings) and the pizzeria will be very busy, so he didn't want to miss out on the chance to have it place to make $30 or $40 over the weekend.

My plan was to recap the G07 from the Ms Pac later and swap it into another machine when the time was right, but after I extracted it, I noticed that there had been a hood with smoked plexiglass installed on the front of the monitor. Removing it revealed some SERIOUS pac man screen burn. This monitor won't be able to go ANYWHERE but right back into a pac cab when it's recapped. I informed the owner of that, and he said it would be fine for me to swap the monitors on site some time after I'm done with the cap kit. I think what I'll do is swap it for a 'no burn' Wells Gardner from my own collection, and keep this one for a possible tube swap later this winter. I'll just keep my eyes open for a compatible CRT TV to show up for free on Craigslist, and swap in a new tube. This site lists the donor TV's -- I'll keep my eyes out for one.

The Arkanoid cabinet is also finished, with the exception of a new tube in the marquee fixture, and a marquee, which I have already ordered from EMDKAY. When those parts arrive, I'll send this one off. I'm considering changing out the monitor plexi to clear, though to aid in being able to see the bezel.

The Tetris cabinet is ready, with the exception of a new tube in the marquee fixture, and locks for the coin doors. The joystick needed a cleaning -- other than that just a wipe down. I am considering replacing the monitor plexi with clear plexi though, instead of the smoked plexi that's on there. You really can't see the bezel at all.

So that's 3 down, and 6 to go!

Here's the status of the remaining 6 cabs:

1. Mortal Kombat II: dead. Won't power up. Currently without a monitor, as it's donated to the Ms Pac Man cab temporarily, and I can't use the swapped G07 b/c of screen burn. Not sure what to do here -- I will ponder it a bit more and work on the other 6 cabs first.

2. Donkey Kong: works, but has sound issues. Parts on order from Bob Roberts.

3. Final Fight: Monitor has been pulled and needs a capkit, bad. Color is way off, and can't be adjusted. I'm hoping to get this done tonight. I won't be putting the 19K7951 back in there, though, I'm going to try and re-use it for the Golden Tee 99 cab. I've started my 'planting of the seed' with the owner on this cab to persuade him to let me have it. "You know, I'm really concerned about this cabinet, I really don't feel it's worth trying to get going again....it looks pretty rough....." hee hee. *note* I may have already bought This replacement Ms Pac Man CP on a whim.......... am I putting the cart before the horse? Hmmmm....

4. Neo Geo: Some progress here! I re-examined the edge connectors inside the League Bowling cartridge, and re seated in in the slot. Next time I fired it up, it worked! I still have no picture b/c it's got the major PITA (= pain in the arse) WG 19K7302 monitor in it, but my cap kit just arrived yesterday, and I plan to cap it tonight. Hopefully I can get the monitor back up again so I can see the Neo Geo LOVELINESS! I'd really like to get a few Metal Slug cartridges and try them out if I can. Maybe I'll try my new monitor extension cable when it arrives and see if the picture will come up on a nearby cab.

5. Golden Tee 99: I tried pulling the monitor out of the Final Fight cab to test it on this one, but that's when I realized THAT monitor needs a cap kit real bad. So, I tried the monitor from my personal Double Dragon cab, but the horizontal size is just a touch too big, and I already know I can't adjust the width coil on that monitor, b/c I've tried. So, last resort is to fix the monitor that was in the Golden Tee cab. Unfortunately, that's the one where the flyback sizzled and I'm really not that confident about my ability to repair it given the pictures I've already posted. Dr Zero (thanks man!) pointed me to All Good USA and I spoke to Carl who says they can fix it. So I may send that chassis in to him to repair it. In the mean time, I found a friend here on the KLOV forums who was kind enough to sell me a pair of K7xxx chassis' for a good price. Thanks, Chris25810! So, by next week, I should have a working monitor in this one and it will be ready to roll.

6. Head On: *yuck*

That's where I'm at for now. This weekend I'll have a bunch of free time to get some cap kits done, so I should be well on my way to 4 or 5 cabs ready by next week.

Thanks for reading!

As Ken Layton has said before these are undocumented factory updates. As long as you don't mess with them there shouldn't be a problem. You can replace the flyback and recap the monitor as you wish.

Good luck with the projects. Did you by chance get these out of the old Hardees Building off 35? That GT 99 looks like it's been fitted for a GT2004+ control panel. Was that the one in Hudson on CL about a week ago that had a monitor issue? If so you beat out the Carbonies pizza by me for it. Ross..
 
Ross!! Good to hear from you again!

I thought I might run into you again on these forums :D

Yes, these are cabs (at least some of them) from the pizzeria on Hwy 35, the old Hardees building. I know the owner through a mutual acquaintance, and he brought me several more cabs from his personal collection (also known as his pole shed *LOL*)

Yes, that's the Golden Tee 99 from CL a few weeks ago, with the monitor issues. I know the seller was trying to sell the cab a few months ago with both the 99 board AND the 2005 board, but I think he ended up selling the 2005 boardset separately. That very monitor is the one I posted above, with the nasty looking deflection board. I'm hearing from folks though that the board should be good to go for recapping and flyback repair, so I'm going to attempt it.

Ross we've met up before....you helped start my addiction 3 years ago when you sold me a Double Dragon cab and gave me a Rolling Thunder cab in the deal. I've since MAME'd the Rolling Thunder cab, and I'm in the middle of restoring the Double Dragon:

http://forum.arcadecontrols.com/index.php?topic=100072

I've come a long way since that cold day in January. I'm head and shoulders deep in 6 more cabs now....

You still a firefighter? Still restoring cabs in your spare time?
 
Yup still doing the same thing just don't have the storage Unit in Centuria anymore. (thank-god). Too funny on the GT99 cab it's always intresting to see a conversion in a Op wolf cab. they never really seem right being anything else. Good to hear about the two cabs you got from me DD is one of my favs and doesn't get the credit it deserves as being a classic. Let me know if you have any ?'s on the repairs. I'm pretty much building games into multi's for customers. (no dedicated original cabs have been destroyed in a long time people). Slowly trying to dwindle down the projects but more just seem to creep in.


Oh by the way on the 7000 I'd for sure re-Cap it, change the Power trans, Flyback and the hot also. Sometimes the critical safty cap will go too. You might want to just change that too B Roberts has them it's the long four legged one by the flyback. The little thing on the top of the metal near the fly I've seen many times in the past cant say what the hell they do but I've seen them before plenty.
