The light strip that is supposed to display the current jackpot value is not functioning correctly. Most of the values light up at the same time, some of them blink at varying rates, some of them turn off altogether at various times during the game. The connectors are fully seated, but beyond that I have no idea what to look for or do to diagnose/fix this problem. Other than this the game is working correctly, no problem with any other lights or displays.

Here's a YouTube video showing the problem:

Anyone have any ideas?

Thanks for the responses. I have LEDs in there now (Cointaker Premium non-ghosting). However, before putting the LEDs in I had incandescent bulbs and the problem was exactly the same. So it is not an issue with the LEDs.

I will check this out later, thanks.

Thanks again for the replies. I ran the lamp test.

The Right Road sign is not working. Everything else on the playfield appears to be working correctly.

For the rest of the test, the first lamp in the test is the 25K captive ball; it blinks and all of the jackpot display lamps are dark. Next is the 50K captive ball lamp, and when this starts blinking the first light on the jackpot display strip also starts blinking. Advancing to the next lamp in the test, the second lamp from the left on the jackpot display starts blinking (and the first goes dark). This continues as I cycle through the test; a lamp in the jackpot display will blink along with whatever playfield light is being tested. After the last lamp on the jackpot display blinks, they will all be dark for the next lamp in the test, and then the left-to-right sequence will start over.

The last part of the lamp test is the jackpot display itself, and they all blink in sequence exactly as they are supposed to. So it appears they are lighting up when they're supposed to, but they're also lighting up when they're not supposed to based on other playfield lamps that are lit.

Just to be sure it's not an LED ghosting problem, I replaced a couple of LEDs in the jackpot display with incandescent bulbs, and that did not make any difference, they behave exactly like the LEDs and light when they're not supposed to.

I hope I explained this clearly, I can take a video of the lamp test if that would help clarify.

I just changed the lamp on the Right Road. It lights up when it's not supposed to in the same manner as the jackpot display.

If you look at the grid that cal50 posted, during the lamp test anytime that anything from row 1 is lit the Right Road lamp also lights, anytime anything from row 2 is lit Jackpot 1 also lights, and so on. For example, when the Bonus 2X lamp is blinking the Right Road lamp is also blinking, when the Miles 20 lamp is blinking the Jackpot 6 lamp is also blinking, etc. etc. etc.

No.

I have a multimeter but unfortunately not sure where. If nothing further can be done until I test the diodes then I will have to put this on hold until I can find it. (Being a military family and moving around so much, things get lost easily.)
