Sounds like the PLL became unlocked.
Re-check your work.
Or take it to a tech.

Did you cut the blue wire?

I hope you used the correct switches or you might have fried the chip...

Sounds like the VCO is out of alignment... try this: Adjust L14, see if you can get the radio to lock back into frequency. Let us know how you get on. Good luck!

(edit) L14 is located left and a little further back from the PLL chip. With the radio knobs facing you, flipped upside down, it'll be located in the front left along the chassis.



~Cheers~

I adjusted 14 and got some of the channels on but no all, some still in the 28 mrz range.
