Lift one side of the diode and see if that allows you to change channels. It won't hurt to have that diode lifted, as that's part of a Cobra service bulletin upgrade. Let us know how you get on.

if i was to replace C179, what size would i replace it with? 22uf 16v?FERNAN 01-
Check C174, 175, 179, and 181 for shorted/leaky. My guess is that it's C179. If it's bad, replace it with an electrolytic cap, not a tantalum. Good luck & 73s.
