👏 Great job!

Also, i appreciate you showing your work and process. Thank you. I enjoy these posts.

Great solution but i feel this is compensating for the signal source being low. Gotta think there is an amp failing or some extra resistance in the signal path. A customer won’t want to pay for the diagnostic time when a fix is available but as an ocd engineer, i’d keep hunting.

The work looks great but it would be educational to know why some of it was done. When a cap is leaking or visibly damaged or a connector visibly burned, it is an easy call. Do you use an LCR meter to tell which caps need replacement? What of it is just preventative?

Do you know when manufacturers started installing these fuses in production?

Thanks Dylan. So glad usps didint lose it after two weeks in limbo.

Working through the holidays!? Keep the games going man. Happy holidays.

Happy Thanksgiving

Keep em going!

Wow!! Very cool for you to walk us through your test bench!! Thanks for helping these original boards live on for more fun times!

Absolutely beautiful job on that board. Thank you very much!

Have not played High Speed yet?

System 11 SOF🎉

Nice,thanks :)

I have a williams high speed main board that boots and starts a game and will complete a game. I see no signs of acid damage. In diag mode, all coils fire. Lights work. Background sounds work. No speech and no engine revs (no lights for rev) I installed new licensed sound roms, made no difference, but I did notice main board sounds are coming through whisper quiet. Luckily, the game came with an extra working board that is now in the machine. Not sure if I should have it repaired or sell the board as is? Is it wise to have a good back up main board?

where did you get all of your test equipment?

👏 Very nice job D.R. That MPU was a mess! Nice save.

Hi would i be able to send in space shuttle pcb for repair if so how can i do so

Hi. What the best way to get a board to you for repair. I have a Firepower MPU that needs some help.

How do you double up the flipper roms?

IT LIVES!

Very impressive work D.R.

Dylan is the man! He does excellent work!

Keep gettin' em fixed! good work!

DR PINBALL, some pinball games ROM chips has a start up problem that while shut the game off if any of the playfield coils are locked close or shorted out. What is this start up program called that checks if any coil is locked on/shorted out? this prevents damaging the solenoid pcb board components like the driver chips and PIA chips. I don't know what the software program is called in the ROM chips its like a test program during only start up

That's so awesome for troubleshooting. I wish more machines were like this in debug lol

Thank you!

Great video Dylan, question for ya here on the TH-cams, because why not. Comments are good. Where did you get these diagnostic boards? Searched the webs and found some threads and a video, but nothing about where to obtain them. Thanks

what is the best option to low the temperature from the lamps resistors on the driverboard? Is it the 5w resisotrs mod or the mosfet mod?

Wow, what an excellent save! Just discovered your channel. Thank you for all these video's, it's really appreciated!

Keep it up Dylan! If you ever wanted to do videos showing you replacing the parts or simple 'how to' stuff I'm sure they would be appreciated!

Absolutely love the bench setup you got there.

Clear Nail Polish / Conformal Coating is fine, The Copper look is fine, I actually prefer that look as well, as long as its not Bare Copper, I think people just say something because it looks Bare.. ( as you can't see the Conformal Coating )

Hi doctor! When you conformal coat the board, do you do it prior to installing the IC’s, resisitors and etc?

Nice job!

Hi there! A friend of mine owns a Millionaire, and he can't get the speech to work. Sound effects, music and everything else works just fine. Sound and speech roms are changed with no results. It's really weird! Do you happen to know, if speech ONLY goes through the front speakers and NOT the subwoofer? 🤔

This explanation seems to be lacking quite a lot. Where does the other side go? Can't still be the slap tilt.

When measuring the Voltage Rails of the Flipper Coil Voltage using an oscilloscope, the voltage will drop dips down each time you press the flipper coil voltage. What can you do fix the flipper voltage from dropping and dipping down each time you press the flipper coil voltage on various pinball games?

Look at all that AMI craptastic memory! :-)

Why does the Flipper coils have their own PROM/ROM chip for the flippers? The original ROM sockets were "not" dual wipe but what are they? single wipe or what

Dylan - Great overview of bulletproofing a Williams board.

Nice work!

Dylan - Great work!

That's a good looking set of boards!

Dylan - Keep up the great work. 🙂

Do you know where I could buy one of these boards as a replacement? Mine is totally fried

Nice work, I find it easier to work on a data east board versus a Williams system 11.

Wow, great job you bringing back from the dead. Happy new year.

DR Pinball when playfield LED's lights are causing flickering ghosting issues, what is are things that can cause flickering ghosting LED or Lamp issues?

Wow, I' have boards like that too. Just to much work for me. Nice job though. What does it coast for the repair when your done?
