How do I know which ballasts control group 2?
Do you remember which sockets were controlling group 2? I probably could have suggested marking them before opening. Whoops. I would check all connections methodical regardless.

You don’t want to hear this. I’d put money on sockets. Why do I say this? It’s part of what I do. This tunnel:

And these ballasts:

Are all for 106 T5’s. Sockets are the most common failure point when flickering or failure to ignite is happening.
This some kind of curing machine?

Lights are on. Very slight flickering in some bulbs. Very slight. Almost like a twitching. Is some flickering normal?

Anyway, this doesn’t mean anything. The fans aren’t spinning (wire obstruction) and…I don’t know. Sign. I need a break.

On first fire they’ll do that. They’ll also look dimmer in the middle for a moment. After a few minutes they should be uniform with no flickering.

So normally N is white or grey but I’m your case it appears to be blue. Check all connections that have an N. No need to pull them out, tug test them. Also I only see 2 leads leaving the contactors so follow those leads to the first connection point. Each ballast only has 2 leads so there needs to be a connection point for the 3 group 2 ballasts somewhere

Some new lamps have a swirl flicker effect which will go away with burn in.

So here are the connections you should focus on first in my opinion. Tug test them, make sure they are in there good. You also need to follow these pairs back (out of view of the picture, possible farther up in the fixture) to their connection point. There will be a set that has 3 ballast leads tied together. The other will have 1 single ballast, that's your two lamp ballast that's functioning properly. You want to dive deeper into the set that has 3 ballasts tied together. Follow that back checking all connections until you get to the contactor controlling it. If alls good, then follow the leads on the opposite side of the contactor to the terminal block I circled and check those connections.

If all are good then we have to go from there. Look at the plug itself, if there is an adapter swap adapters and see if it symptoms change channels.

They look like contactors to me. The tiny display probably cant handle a load so it just controls the open/close function on the contactors. I think the module above is probably for 0-10v dimming?
If they’re contactors, that could be the culprit. If that flickers everything downstream will flicker.
