Need suggestions on Toshiba TV problem: (Model CF2750K, chassis # TAC-9011, Mf'd Nov 1991)
It works pretty well much of the time, but the Automatic Frequency Contol seems to
be "straining" to lock on to a channel after changing the channel. It usually takes a
second or two for it to "pull in" and lock. Sometimes it does not succeed, and seems to
lock in between two adjacent channels....sound from one, and weak video from the other.
My intuition is that there may be a single Capacitor-trimmer, or Potentiometer that
might "re-center" the "capture-window" and provide more certain "lock-in".
Can anyone suggest a specific adjustment, or an approximate location based on a similar
model? I do not have a schematic diagram. Thanks in advance!
(I was fortunate enough to get excellent advice recently which cured my Vertcal Linearity
problems!)
