Quoted from mark532011:

Got a question about one of the digits display board on a Harlem Globetrotters. The board is shown here:

In the center, it looks burned. Here is a closeup:
Do you think that looks bad enough to replace the component? I am guessing all 3 resistors would have to be replaced, would there be anything else? Are all the boards the same? (I can get the values from the other boards)

Quoted from Jason43:

If I recall, I think you can set it to 40, although I could be mistaken. I'll check the switches, but I'm not sure the issue is related to that. You can drain the credits playing games, but as soon as you turn it off/on, they reset to 40 and the high score gets wiped out. It's pretty odd.

Quoted from vec-tor:

I have one installed in a Bally Centaur and it is still holding the data. Thumbs up.

Quoted from Quench:

Test point TP3 that's connected to pull-up resistor R70 on the Lamp Driver Board is there for manually testing SCRs. Connecting a wire from TP3 to the gate lead of any SCR should activate the respective lamp.
It's mentioned as part of the Lamp Board diagnostic procedure in the Bally Repair Procedures manual FO-560
There are also pull-up resistors connecting to test points only on the SDB that are used for similar purposes.

Quoted from desertT1:

If I had to pull a few chips and reseat to have the game boot after having fine that less than a few months ago when I got the game, what should I do to make it more reliable?

Quoted from DrJoe:

The latest line-up with a few system 7s thrown in....

Quoted from srcdube:

Ceramic... around the fuse wire. Helps dissipate the heat.

Quoted from srcdube:

Definitely... probably some other application like an appliance. I often have a hard time finding fuses at a hardware store instead of an electronics store... there’s so few of them now. If it was able to force fit.. ok. But check the value to be sure it’s correct. When it’s ever replaced you’ll likely need to squeeze the clips together again.

Quoted from Buzz:

Happy Thanksgiving and a once again functioning Playboy after replacing this rectifier board.

Quoted from Heaterguy:

i repinned the .156 pins, dont have the small ones for the red mpu connectors though.

Quoted from jibmums:

Anyone have a source for these? I can't even find a part number anywhere. Marco carries the common 1/2" version but not this larger one. I've also checked Home Depot, Ace Hardware, etc. with no luck. May just wind up using a rubber washer as a replacement.

Quoted from Phesson:

I just replaced the flickering leds in a Mata Hari with incandescents. Now the displays for player 2 and 3 are pointing random numbers along with player one scoring. I unseated and re seated all the connectors with no luck. Any advice on where to start on this? Could I have shorted something during the light swap that would cause this problem?

Quoted from Quench:

You've got the wires soldered on the wrong lugs (backwards). Swap them around so the white-red wire connects to the diode lug on the side and the brown wires go where the white-red currently are.

Quoted from northvibe:

Now that GPE and BDE are closed.

Quoted from greatwichjohn:

Just finished repairing & cleaning up a Cybernaut. A old guy died & the people looking to cover some funeral expenses unloaded the pin to the operator. Came out of a basement, & they decided to cut the wiring harness to the displays. One bad display, all rubbers bad & some missing. Wrong fuses, most of the lights burned out, & never cleaned in years. The operator is going to put it next to Vector on his mall arcade.
