2245 Tuner Lamps not coming on

Well I was trying to replace the burnt out lamps in the meters and the tuner dial, one was working on each
and in my tight spot I did something unfortunately!!
All bulbs have been replaced, the aux,stereo, AM/FM,phono etc are all working, but the meter and the tuner dial is not coming on.
I have individually tested each bulb and applied external power to it, and it's all functioning well, just not on it's own from the unit itself.
I have check all four fuses internally they check out, the rear fuse is fine, so now I'm at a lost since there appear no power on the two green wires.
Unit powers on and works.
Have I blown a lead of the transformer or something?
Any help would be greatl appreciated.

Did you pull the fuses and test them with a digital voltmeter? Do you have the schematic for it?

The green wire not pinched or broken? Start with the basics. The real experts will be along shortly.
 
I had to replace the one fuse, the 2 amp on the board, which I thought was the reason the whole tuner wasn't lighting, replaced, tested them all attached to the board and all tested well.
 
It is very common when fiddling with the lamp board for one of the wires to break that attach to it. Brittle wires, old connections, etc. Look at the wires that attach to both ends of the board - especially the green and black wires near the tuning knob end. Check them at the board and trace them to the other end. In the few units I have rebuilt, I have had one of these wires break a couple of times.
 
I also had a light board that someone thought the proper replacement lamps were actually 250ma agc fuses!
The burnt foil trace saved the transformer windings but killed the feed to the lamps.

There doesn’t show any power coming up from under to the fuse board.
Here’s a few photos if that helps.
Much Appreciated
