The television chassis has suffered some damage. The fine tuning portion of the channel selector shaft has broken off.
I am able to turn the fine tuning control from what's left of the shaft, however it simply spins freely, the shaft must be broken internally as the fine tuning capacitor (C9) does not move. I thought perhaps the capacitor could be seized, which would account for the breakage, but I can adjust it manually.
I am considering a repair to this part of the set depending on difficulty, and whether or not an original shaft can be found, or the original repaired.
