I can almost hear sound when turned all the way up ( aux turned up as well )
When I shut game off it buzzes loud into a fade a way.
No noise when a adjust volume.

That is just a terminal strip with a resistor on it.

It looks factory, but I'll check my game photos to see if appears in mine too.

I'm not sure what could be causing the audio issues. Does it seem to work normally when playing a game?

Yes game plays pretty good ... Few minor issues ... Sound has me stumped.

You guys are the guys I need to talk to. I bought a ME that is in pretty good shape. I plug it in and everything works. It scores (it scores 10x of the value of things, 200 becomes 2000 etc...I'll figure that out later). The flippers work. The sound works. Everything seems okay. Before long though...it starts firing all the coils as you mentioned above....like something is over heating...or something. Turn it off for a while and turn it back on and it works again for a while, then....BAM BAM BAM! I have read through this thread several times but I'm not getting what you did to make the coils stop firing. Could you please clarify? I really appreciate the help.

Ming, my ME did the same thing. I still don't know what caused it, or what made it stop. Only thing I can offer is to get into the power and re-seat the connectors going to the full-bridge rectifiers. You could have a loose wire that's making poor contact. Once the game warms up, the connector loosens more, causing the voltage to drop out to the logic board, throwing it into a reset loop. I was poking around with the rectifiers on mine when my table stopped freaking out.

I really appreciate any and ALL suggestions...I'll give it a whirl, it must be something simple like that because it works and then it does not. I am a novice at these machines. I started with a RO GO and moved on to FLASH GORDON and now this ME. I am really digging the pinball community....you guys rule. If I can ever help anyone with their Vintage Motorcycle please don't hesitate to ask....I'm really good with those.

Thank you again! I'll see you guys at Texas Pinball Festival

This is a normal setting for this pin .... I believe it was done to bring the scoring up to date with the other pins at that time.
Mine had a factory sticker saying all scores multiplied x 10 .... Or something like that.

The scoring is a dip switch (dial? Can't remember now) setting. I changed mine back to score properly.

Middle Earth still has a voltage drop problem, but, it only goes BAM! once or twice and then quits instead of going into an endless reset loop which is a huge improvement. I spent all day cleaning contacts and getting bulbs to work. I decided on black for the legs as they were really nasty. It still needs a LOT of work but I think it's safe to say that it has escaped "paper weight" status.

I really appreciate you guys help. I have a buddy coming over tomorrow that fixes musical equipment for a living and he's gonna have a go. I will keep you apprised.

Thank you again.

Gotta say, compared to mine, that ME is in amazing condition! Wow.

FIXED! Had a guy here in Houston redo both the original board and I was able to get my hands on a A006020-02 "Universal" board on Ebay that he also fixed and set up for ME as a back-up, he also did the AUX board. The guy is an Atari fanatic and has all the machines to properly test & burn in boards. Ebay user:ebay.com link

Still needs a bit of tweaking but I'm really happy with it, I love the art and how rare it is, especially in this condition.

I appreciate all the help you guys gave me, thank you!

Hey guys!
I also just scored a MIDDLE EARTH PIN about 3 weeks ago. I shot some video and eventually got it up and running - as it was given to me not-operational!

take a look!! got it from bringing it home all the way to a preliminary gameplay video!

maybe you guys can give me a better idea about how its playing - its my first pin and I feel I am learning a lot. Now I am just getting the playfield up to spec, making sure everything should be responsive and work as it should.

Looks Good ... I need sound on mine

#65 2 years ago

If this thing was just bells and chimes id probably put it down, but I seriously LOVE those old 8-bit sound effects!! I wish there was a knocker for the extra ball however. I am curious to see why no one has mentioned it before that Atari pins don't seem to have a knocker for extra ball or when you hit 50,000 points. There is a longer and louder sound effect to make up for it I guess.

Must be a dip setting... mine does the noise at 100,000.

Atari coded a knocker output for replays and specials, but they left out the hardware to make it happen. In the manual for Middle Earth, they discuss the modification needed to make this work for audit counters, but the same changes can easily be made to drive a solenoid instead. All you need to do is add a TIP101 transistor, a couple of diodes, and a stolen knocker assembly from another game.

I'm in the process of doing this on a Middle Earth that I bought from the Church of the Silver Ball... I'll take lots of photos and document the modification.

Mod completed and it works great. Every Atari should have a knocker! https://pinside.com/pinball/forum/topic/atari-middle-earth-club-group-all-welcome#post-5305264
