    All th channels are fine up to and including 32 then nothing until you get
    to 51, I did the solder job but it did no good. Any ideas.

    Are you using cable or on the air signals to test?

    I thought that problem sounded like something I had run into before. I
    went back to my old fixfindr program & came up with this, measured 15V
    at U7501 pin 14, but 0.34 at CR7108. R7514 checked good in
    circuit,but the 15V drop was across it. bridging another 100K across
    R7514 restored normal voltage at CR7108& normal tuning Hope this
    helps C harles
  4. Why not the common problem of corrupted EEPROM?
