I just picked up a non working ‘83 Atari Star Wars Standup

I just got a non working ‘83 Atari Star Wars standup arcade in a trade, and was hoping for help diagnosing its issues.
I’m not much of an arcade guy, so bear with me
It’s the ampliphone monitor setup. The machine was complete minus the monitor, but the seller found a monitor to include in the trade, which I installed last night. The best I can tell, it is the correct monitor for the game. Can anyone tell me if that is indeed correct?
It powers up, marquee lights up, monitor is totally dark but has neck glow, but it seems to go directly into a test mode with 1 deeper sounding beep followed by 15 beeps. Then keeps repeating that pattern.
If anyone can other any guidance that would be fantastic!

The Beep pattern is an error code. Atari's usually had a large paper sheet stapled to the inside of the back door showing Dipswitch settings and error codes. You may have to search the net to find it.

The amplifone looks about right but I haven't seen one in about 30 years! They made one for 19" and one for 25" for the Sit Down cabinets. As I recall, it was the HV unit that was different, or at least adjusted and sealed differently (HV Shutdown etc.).

I am sure you can find more/better info over at KLOV.

Amplifone was the more desirable of the two that were put in those. They however need a bit more work in general. Nice find!

It all looks right. I have one with an AMP in it.

But be warned:

It could prove very tricky to get the PCB working.

It could prove tricky to get the monitor working.

It could prove difficult to determine which one is failing. As of now, I can confirm the beeps are the board telling the operator that there is an error.

Amplifone's are great, once they are bulletproofed. Good luck

I have used Chad at arcade cup in the past for repairs on amplifone monitors. He does really great work:

If I remember correctly he charges about $185 to repair and bullet proof one of these.

Yes I do have it on the back door, but it shows nothing regarding the beeps. I'll look online for a manual.

Yes, that's what I'm figuring a I read more about them. Thanks, I'm pretty excited!

I was already starting to get scared from what I see online, you're not making it any better

Well, I have spare boards if you can confirm anything has failed.

Ok awesome! I'll see what I can get figured out...

Haha, nice work!

Mine has 1 "boop" followed by 15 "beeps.
Does that mean "(1) RAM 2F/H on the CPU board (a 2Kx8 for the CPU)" has failed?

Here's the info from the link:

A "beep" means the component tested OK.

A "boop" means the component failed the test.

There are 16 beeps followed by a pause. After the pause the pattern
repeats. The beeps correspond to the following:

1) RAM 2F/H on the CPU board (a 2Kx8 for the CPU)
2) RAM 5F on the CPU board (a 2Kx8 for the Matrix processor)
3) RAM 5H on the CPU board (a 2Kx8 for the Matrix processor)
4) RAM 3L on the AVG board (a 2Kx8 for vector RAM) ***
5) RAM 3M on the AVG board (a 2Kx8 for vector RAM)
6) RAM 4P on the AVG board (a 2Kx8 for vector RAM)
7) RAM 4L on the AVG board (a 2Kx8 for vector RAM)
8) RAM 4M on the AVG board (a 2Kx8 for vector RAM)
9) RAM 4P on the AVG board (a 2Kx8 for vector RAM)
10) NOVRAM 1E on the CPU board (a 2212 Xicor 256x4 NOVRAM)
11) EPROM 1F or 1M on the CPU board +++
12) EPROM 1 J/K on the CPU board
13) EPROM 1 K/L on the CPU board
14) EPROM 1F or 1M on the CPU board +++
15) EPROM 1 H/J on the CPU board (The daughtercard for ESB)
16) EPROM 1 L on the AVG board ***

Did you say beep or boop?

Not knowing what my next move should be, I pulled the CPU boards out, pressed down on the RAM 2F/H chip (because it was giving me a failed RAM 2F/H code on the CPU), then made sure everything on the board setup was securely plugged in and tried it again, still nothing worked.

So I put it back in test mode with the switch, but it won't enter test now. Anyone have any thoughts on why it won't?

And I noticed that the marquee and coin slot lights are super dim now, does that imply a voltage issue?

See if you can see if one of the legs have snapped. They can be fragile. Verify voltages coming off the ar2 board. Every Atari I’ve worked on needed new caps and/or transistors. I would unplug the monitor and it’s boards just to be safe. Check the fuse block. When I had a flaky ar board I kept blowing f4 if I remember right.

Thank you. Which legs do you mean, the one coming out of the board to the connectors?

Here’s my voltages on the AR2 board:
My 10.3 is 11.08
+12 is 11.92
-5 is 5.00
-22 is -23.70
+22 is 23.30
36 VAC is 18.02

While I was at it I tested a couple on the MPU:
+5v is 4.97
-5 is -5.18
10.3 is 11.19

Oh sorry, on the ram chip. The legs of the ram chip you re seated. I’ve had an awful time lately snapping one if I look at it funny. My concern would be it broke and slid sideways making contact on a couple pins.

And if I remember right the 36vac was measured on two lines. I gotta look at my roadblasters and figure out how I did it. It’ll be a tad diff since it’s a raster, but the ar boards have more similarities than differences.
