Okay, had BW for a while now and it has some ghosting on the LED's from obviously faulty diodes.
Now the question, is there a QUICK way to trouble shoot as there is a lot of lamps in this beast and it appears over 2 columns?
Don't want to disconnect ALL the individual diodes on the lamps to test, any help please?

Trouble shooting LEDs and lamp matrix = STOP !

Go back to incandescent globes and see if the problem persists. Now you know there's no problems with the game.

Invest in Ghostbuster LEDs. Expensive, but they are a much better solution. I learnt this the HARD way with a collector that bought cheap junk LEDs. He was told the problem was with his game, not the junk LEDs. Replaced with GB LEDs and the game is perfect.
