Hi,
My T2 has no light in the left side of the playfield.
I have replaced the J115 connector and socket.
I have also moved the connector from J120 to J121 without any effect.

What should I try/test?

I tested the fuses and they where all fine.
I also measured around 7.6 V AC on each fuse.

What is the next step? I really don't hope its a big problem...

Where on the wires? On the connector or? I guess its the purple and purple/white for sure thats not working

I measured the outputs. On AC. I got 6.6 on orange. Purple nothing.
What are the next step now I don’t measure anything at the connector?

This one? (If it did not help)

Uhm I think so? Do you know what the other one is? It’s the whole left side that is out. Both top and bottom.
The only other gi issue I think I have is that I think the cpu in the middle (green wire) seems a little dim. But I have not measured the voltage on it yet.

Thank you all for the help. Problem is solved!

J115 Leg 12 on the socket was not soldered good enough.. What a stupid mistake.
But at least I checked all connections now and learned what to do next time.
