RFM lamp issues help

Print a copy of the lamp matrix from the manual. Put the game into individual lamp test and step through each lamp. Mark on the sheet you printed, each lamp that activates when they shouldn't.

The way the lamp matrix works, there has to be a column or row correlation with this kind of behavior. Using the printed sheet that you can mark up will allow you to visually see which row or column is affected.

Quoted from pacmanretro:
Thank you for the suggestion...I had started that previously and it seemed all over the place. I am starting a more thorough job of that right now.
If a lamp test causes other ones to come on too, do you think I should mark the lamp that is supposed to light, the extra lamp(s) that light, or both??
I would think both, but not sure...
Thanks

Mark them differently so you can tell the difference. Different colored markers are good to use.

Are any of the other diagnostics affected? Do the coils all engage properly in test? Do all switches respond as they should?

You'll save yourself and others a heck of a lot of time and headache, packing up the driver board and sending it out for repair.

You won't follow the troubleshooting suggestions given. Your comments show that you're clearly in over your head. This issue will likely require some board work, and I can't see that ending well from what I've seen so far.

Also not trying to be rude, just one guy's opinion. I hope you get it resolved easily.

Well it definitely sounds like you've got more than enough experience to tackle anything that needs to be done. My apologies for rushing to judgment.

Most boards I get in these days have been destroyed by hands that had no businesses being near them. So my reaction is hyper sensitive. Again, my apologies.

Confirm you're dealing with a board issue by swaping J106/J107 with J108/J109 on the driver board. One connector is 16 pin and one is 18 pin, so you'll need to match pin one to pin one. Pins 9 and 18 will hang over the header on the smaller of the two.

What you're doing with this is swapping Lamp Matrx A with Lamp Matrix B. So if the issue remains exactly the same on the playfield it's not a board issue. If the other Matrix lamps are now affected, then it's a board issue.

...
Am I correct in thinking it followed the same lights from either section of drivers? Therefore less likely to be a board issue???...

It's not less likely to be a board issue, it CAN'T be a board issue.

You've got a wiring or playfield issue. Anything from the connector out of the board to the lamps. A shorted socket(s), bad diode, shorted wire, most anything, except a board issue. Very difficult to find, but should be very easy to fix once you locate the cause.
