Picked this up a few weeks ago from Mikdawg (Greg) and also thanks to RenegedeFred for driving it my way. Got a good deal but it's a project! Started it up and you can hear the monitor buzzing, the coin lights go on, fan, and marquee. There are no lit up LEDs on the boards. Greg told me he installed the power supply repair kit from Bob Roberts so there are two newer big blue caps on/etc. Not sure why I'm getting no power to the board. I know the monitor (G07) definitely needs a cap kit but wanted to get the power supply/boards working first. I'm not familiar with these types of power supply units. Not even sure how to adjust them.

Any help?

Any help on the Atari Brick...When I power the device on both F4 and F5 fuses blow. The voltage plug is yellow (120v) on the brick. I tested the molex connector J5 and I'm getting ~ 15.6 DC in 1-3 and I'm getting 60AC in 10 - 12 and 60AC in 13-15.

Thanks!

From what I can see in the pics, looks like your monitor has already been capped in the last year or two.. Same with the power supply (I think). So you might want to re-check the work done on them.. If your blowing fuses, its power supply related..

Thanks Pete. Could the AR III be the cause of blowing the fuse?

I've looked over the power brick and can't seem to find any issues. The bridge rectifier is hooked up correctly. Both big blues work fine and all the orange wires are hooked to + and violet hooked to - .
 
The bridge rectifiers are a common failure point. Do you have a meter that can test diodes? Even if not, you can check for shorts - and a diode short would cause fuses to blow, though I haven't looked to verify F4&F5.
 
Tested the bridge rectifier and it was fine. I replaced it with a new one too just in case. Replaced the fuses and all good now. wtf. Capped the ARIII board with Bob Robert's repair kit and still nothing. Checked continuity on my caps and seem fine.

Still not getting red lights on the main board. Tested the ground/+5 and get nothing. I'd assume it's the board?
 
I know this might sound dumb, but did you check your voltage at the end of your harness? Before you connect it to the board? How's your edge connector?

LOL. OK checked the cable at the board and nothing. So I check the molex connector on the ARIII and get no power on J7 except for #4 15 volts dc which should be at ~10.3 but it's unregulated so I'd assume that's fine. So I'm checking the harness that goes to J6 and again just getting the DC voltage at 4,5,6 (orange wires) ~ 15 volts. I'm getting .2 AC at 7, 8 (red wires).

So looks like I need to go back to the power brick? Could there be an issue on the harness from the brick?

Any insight would help! Thanks!

EDIT: Damn it the F4 and F5 fuses blew again and those are the red wires. There must be something wrong with the brick!

Well, I'm terrible at figuring out stuff like that. I know bricks have gone bad, but not usually. You wouldn't happen to have another power supply you can test it with?

Negative. Nothing to test.

Thanks.
 
I finally got a minute to look at my game. To me, it seems like your motherboard is different from mine (sorry for the phone pics):

BTW, the only light that's on when it's running is the bottom left one, toward the back wall.

Your power supply is also different...mine's running on a switcher:

I'm really not the guy to ask how or why, but they're obviously different. I don't know if they had different revisions of the board, or what. I also don't know if the different revisions required different wiring, etc., but I doubt it. If there's anything else I can do, I'm happy to help.

Derek thank you for taking the time and posting the pictures. Much appreciated.
 
So now I'm having issues with the PCB board.

Two issues pop up:

"Bank Switch Error"
"Ram at 03000 error U L F2FE"

8511285053_28f950333d_c.jpg


Looked at the slapstic chip and noticed it has a leg broken off and it's stuck in the socket. Am I screwed?

Moreover how the hell am I supposed to know which upper and lower roms are 03000? These numbers don't mean anything to me. Also what does F2FE?
 
For the rom and bad chip locations you need the original manual which has the cross-reference shcematics and shows the location of each chip and how its position is labeled.

i have included 2 screen shots for you of the SELF TEST from the manual and the IC locator so hopefully you can find your bad chips...

Referencing the faults you recieved the Self test page says "ROM at 30000 error is in U = 14B and U = 14A

*** Also the manual says to "press player 1 start button while on the error screen to continue testing the board for any other errors ***

Good Luck

Thank you sir! At least now I know which roms were bad. I pulled them out cleaned them off and made sure the solder joints were good. Put them back in and the same issue :-(

I'd assume my next step would be to burn new roms for those?
 
Well i couldnt tell you what the next step would be since Im still new in this repair game also, but if it were me I would definitely start searching for replace roms or untested boards for parts.

On a side note, check your runs from the roms and make sure that you do have continuity and there aren't any cracks that can be causing the failures. From my experience in electronic repair (not arcades) a self test will send a few bits of data to a chip and expect a certain value to return to verify the communication was successful, when this doesn't happen the self test will toss you a faulty code indicating the fault and where to start looking. If the transmission line that carries or returns the self test signal to the micro-controller is bad it could cause you to get these errors even if the chip-set was good.

Hope this helps

Perhaps, the slapstic IC is responsible for bank switching and is specific to each game Atari made (with a couple of exceptions), so it is basically a security chip.

I had a similar error and it was due to a bent pin on the slapstic, repair log here.

So it is highly likely that it is causing your issue, you wont be able to find a replacement so your option is to repair the chip itself. If you are not very good a soldering I would recommend you post a very good photo of the chip and find someone who will attempt to fix it by dremmeling the edge of the chip back to metal and attaching a new leg, or soldering a new leg on the side if your chip is the same design as mine was.

You really will only have one shot at fixing it so it is not the time to learn soldering if you are not already skilled. Post a photo of the slapstic chip and we can see whats what.
 
The bank switch is definitely the slapstic rom. I pulled it out and one of the legs is stuck in the socket. The issue doesn't come back anymore since I put it back in. There is still a connection but it's definitely not fixed completely.

I'll ask Hobby Roms if they can burn me two of the roms I need and go from there! I'll keep you all posted when I place the order/receive/etc.

Thank you guys!
