2 controlled lamps are working in all tests (single, column, row, and all) but stop working in attract mode or Gameplay.
I've changed the LEDs and even 1 of the sockets with no avail.
Here's a quick video of the issue

Incandescent gives the simular results - Except that 1 incandescent went out on 'All' test
All fine in the test modes and they stop working shortly after being put into attract mode

Testing with Incandescent with almost same results

Multi meter testing is getting 530 at the 2 trouble sockets.
Receiving nothing at other sockets

I noticed that the yellow COLUMN wiring ends on ROW 2 (Rescue MJ) , not ROW 1 (New Goblin).

I just picked up the game a couple days ago. I'm not sure when it started, but it was before I purchased

I was going to remove all the light in the column and plug in 1 at a time to help diagnose and my game did a reset "pop" (turn on sound) and the DMD was frozen. Momentarily later, it reset.
Now, it's not booting.

With the CPU board disconnected from power:
The driver board is only sending 4.4v to the CPU board on the 5v lin
The driver board 5v LED is on, but it only has 4.38 at the test point.

With the CPU board connected to power (and not booting)
The driver board 5v LED is on, but it only has 2.7v at the test point.

I removed the LM338K heat sink and the 5v is nice and strong - game is booting again

I still gotta work through the lamp issue though

After removing the entire column, except the 2 light with problems, it gave the same results.
I removed all the lights in row 1, same results still.
I started testing all diodes in the column and found the pop had a suspicious DOTS (diode on terminal strips) with close wires.
I pulled it out, tested, and examined - it was OK, I put it back.
After turning on again to test, it worked.
IDK what the issue is, but possibly linked to the DOTS on that column.
I'm happy that it working but still kinda curious as what was the cause.

After upgrading all the inserts into non-ghosting LEDs, the same 2 inserts stopped working again. Luckily, I had a quiet chance to cycle through the tests and was able to hear buzzing on that column. Following my ear, I found the culprit, the Doc Ock Spotlight. There was a piece of metal (for the train car mod to rest on) that was causing interface when the post was tightened up. Once the post was loose, the problem went away. I have removed the metal piece (train mod was removed previously) I am glad to finally KNOW what the cause was.
Posting this to help anybody that might end up with a similar experience.
