I'm stumped. All the lamps work on my QS. When I'm in test mode, they all blink. What's weird is that the 3,000 bonus in the center SOMETIMES works as it should, but then other times, it will blink in sync with the K target lamp, not turn on at all, or just stay lit. Any ideas?

Quoted from Inkochnito:

Check your print headers on the lamp driver board for cracked solder joints.
Oxidation on the headers is another cause.
Also check J1 on the MPU board.
If you have a spare LDU exchange them to see if it is on the LDU or something else.

That's good advice but both of these boards are brand new!

Quoted from Quench:

Sounds like the wire for that lamp might be in the wrong connector position at the lamp driver board.
Schematic says the 3000 bonus lamp is a black wire. And it comes from the lamp driver board at J3 pin 26. Note the lamp driver board connectors start with pin 1 at the bottom and count upwards.

Spot on! The 2x and 3k bonus wires were flipped (both are black!). Thanks again!
