20191204_191656.jpg20191210_173622.jpgQuoted from Mathazar:That backglass on Marco's looks like the '81 version and your machine is the '81 version. One good indicator of that is the silver lift bar on the bottom of your installed backglass in your pix....1981 models lift out. The '84 EBD door swings open with the backglass installed and it slides out once the door is open (nice design, IMO, and convenient for quick backbox maintenance).
The dimensions of the 1984 EBD backglass are different and thus much harder to find. I also sent the dimensions of my '84 backglass to CPR last year to aid in their reproduction efforts. Fortunately I don't need one...my original is about a 9 out of 10.
Ahhh I missed the 84 part. My bad!

I recently replaced my lamp driver board with the Alltek Ultimate LED/Lamp driver board as the old board would not light several bulbs. After installing the board all the lights work (I am using lamps not LEDs) and the solenoid expander board was vibrating in attract mode. When a game is played the vibration stops. I read up on the solenoid expander board and saw that the vibration may be caused by the connected bulb burning out so I replaced the bulb and the vibration stops. Unfortunately now the DELUXE lights, corner pocket lights, and bank shots lghts stopped working and the left orbit lights are either all on or all off. I checked them in test mode and nothing changed. I tried the old bulb on the solenoid expander board and the vibration returned but the lights did not. I played two more games and all of a sudden my right flipper is machine gunning.
Is it possible the lamps and flipper are related or are these issues unrelated? Any ideas on what to check first? I am also running an Alltek MPU and Alltek Solenoid Driver board.
Quoted from TreyBo69:What do you mean the SEB is vibrating? Like the relay is locking on?
It would buzz intermittently, about every 8-10 seconds. It was pretty loud.
I am positive they are all lined up correctly although I am not positive that the connectors are all in great shape.
Can anyone help me diagnose a new problem on my 1981 EBD? I have an Alltek MPU board and the game is set to free play. Game boots up properly, sound is on, lights are all on, press the start button and nothing happens. Checked the leaf switch behind the button and everything is making proper contact. No idea what to try next. Any help is greatly appreciated.
Quoted from Alan_L:Did you check the under playfield fuse?
Does the outhole switch close with a ball in it?
Double check all connectors in the head, not just the Alltek, all boards.
Under playfield fuse is good. I will check the outhole switch and the connectors.
Quoted from Mathazar:Does the EBD go into Self Test ok and pass the solenoid and switch tests? Is this a problem that just started after working for some time or is this a newly install Alltek board?
Alltek board was installed about 3 weeks ago and has been working well. I will try to solenoid and switch tests. The problem began yesterday after the machine had been working great after I replaced the right flipper coil (it was machinegunning). Had many family members over the last week and the game saw a lot of use and all was well until I turned it on yesterday and could not start a game.
OK now when I turn it on I get all the lights but no sound. Solenoid test appeared to work perfectly. Still cannot start a game.
Re-seated all connectors and still nothing. Outhole switch is working. Sound board was re-capped and repaired 3 weeks ago by a professional.
Quoted from Alan_L:Re-flow header pins on Solenoid Driver board? Losing sound when you had it before sounds (haha) like cold solder joints.
By "all the lights", do you mean G.I. and feature lights too?
Does the game reset the drop targets when you start a game?
Do the displays go into attract mode at power up?
Power Supply/Rectifier board: check fuses. Check voltage levels at Test Points 1, 2, 3 & 5. With a lot of play, you may have blown a bridge, especially if there were any little kids going flipflipflipflip.
Solenoid Driver board is a new Alltek installed 3 weeks ago. I get all GI and feature lights, displays go into attract mode, and drop targets reset on power up.
Quoted from Waderade812:This is probably a long shot. But have you checked the tilt mechanisms including the ball in the roller tilt. It just seems that if the game is firing up on the boards but won't start a game at the game start button. It may be tilting right away.
Just checked the tilt mech and roller tilt. No change.

The 2X target on my 1981 EBD intermittently does not reset between balls, I would say it stays down 20% of the time. When this happens the player gets 5,000 points at the start of the ball so the game realizes that the target is down and it does give a double bonus at the end of the ball. I had the drop targets replaced by a professional back in December and this problem only started in the last week. I suspect that the 2X target is sticking on something but I am not sure what to look for, everything looks solid as far as I can tell. Any advice would be greatly appreciated!
Quoted from mbeardsley:When the targets reset, does it "stay down", or does it come up and then fall back down again?
If it is falling back down again, then it may be a couple of things -
1) the spring that pulls the target forward and down, is broken/loose/missing/weak
2) the small edge on the target that is supposed to catch on the edge of the playfield may be worn down
3) the edge of the playfield itself may be worn, preventing the target from latching onto it
If it is not coming up at all, then most likely there is a problem with how the target is attached to the reset arm...is it missing the cotter pin that holds it on?
When the 2X target does not reset it stays down. I will check the cotter pin! Thanks!

Quoted from Tecomd:So, finally took on a full playfield swap of my '81 EBD. I converted the individual lamps to to PCB boards, as in the limited edition. I have used this site for many good tips...only fair to post a pic of progress thus far. I went a little overboard on the zip ties.[quoted image]
Looks great!
How hard was the PCB board conversion? Where did you source the PCB boards?
