Hey guys, new to the site and got my very first pin, future spa. It was given to me with the hopes of it being played. Covered in dust and debris for many many years I got it home and cleaned it up. I pput it in my garage while working on it. (55°). Cold I know but I didn't want to bring it in my house until I had it probably working...I plugged it in and everything on the play field works, sling shot, bumpers, lights, drop targets, etc. My problem ive had from the get go was the display boards.. sometimes they worked great, other times they pulsed some. It seemed to be keeping score correctly and after 3 weeks I wanted to bring it in... I had a friend help me take the head off to get it in my small game room. (He has 2 pins and had to do the same thing on his) we labeled everything with tape and everything went back exactly the same. After we're got it in the house which was way warmer.. got it put back together and fired it up.. the score board seemed to throw out some random numbers on boot up. Then it settled down and we played a few games. I turned it on later and it was not wanting to boot up or kick the ball out.. I hit the reset on the coin door and it went through its test. Nothing. Shut it off. Turned it on and then all it says is 11 on all the displays. The field still plays fine and it keeps some what of a score before it drops off points or adds a bunch of points still with 11 in the last two digit spot on the display board. I pulled all the displays out, checked the pins, hit them with my soldering iron and fresh solder. Still the same. I pulled the mpu out and it looks as if it's been repaired in the past (smoke, grinding) so I hit those again thinking one might be cracked free, again nothing. Im looking at everything online I can find.. j4 seems to be common thing brought up in this topic, alltek board, among a few other things . before spending money on a new board I would like to try and fix it on my own, I'm really new top this type of thing and I'll be honest I haven't done much electrical. Any help idc much appreciated
Thanks guys

With power off, try reseating the top left connector on the MPU board.

#5 4 years ago

That did nothing

It is just cycling through these ... I can hit the start button and play a game but the scores will go all over the place

Unplug all but player 1 display. If it still acts up, reseat that connector on the back of the display.

don't plug-unplug displays while power is on !!!!

couple things .... there is 190v DC ( oneHUNDRED NINETY VOLTS) ... it hurts !!!!

from pinwiki: "" 5.12.2.4 The Same Number is Displayed Multiple Times During Display Test

If one or all of the displays show the same number more than once during display test, (ie. instead of 0,1,2,3,4,5,6,7,8,9 being displayed, 0,0,2,2,4,4,6,6,8,8 or similar is displayed), the 4543 decoder chip on one of the displays is probably bad. To test this, turn the power off, and disconnect all displays but one. Continuing performing this procede until the suspect display is found. DO NOT REMOVE THE CONNECTOR FROM THE DISPLAY WITH THE POWER ON. This will result in damage to the MPU board, the display, or both. ""

Quoted from PinballManiac40:

Unplug all but player 1 display. If it still acts up, reseat that connector on the back of the display.

what he said with "safety first "

Time to reflow the solder joints on each Connector pin on each display circuit board. Also, reflow each plasma display lead on the circuit board.

After this, if you still have a problem, time to wiggle the wires going into the connectors with all displays installed and the display test cycling. Alternately, you need to trace the daisy-chained data lines between diisplay boards. There is likely a bad crimp or broken wire at a crimp-on terminal.

Will it hurry anything to just use the two good boards to play while I fix/replace the others?

#14 4 years ago

Will not hurt at all.
