Bulb Holder Printed Circuit Board

[boloboss]

I change my bulls to LED and a new printed circuit board. I'm having problems with getting the bulb holders to make contact on the circuit board. Some work, some don't. I wiggling, then change direction as I'm twisting in...then they come on ( but not all)
Q: any advice

On mine, I cleaned the contacts on the holders really well, and cave them a bit of a polish with a high grit sandpaper, and cleaned the traces on the circuit, and bent the contacts out a bit to make a better connection, and it worked for me
