Almost impossible the FBT is bad. Did you check for cracks on
the main board ? This set is quite simple, dosnt even have a
regulator. if the board is OK I can give you a few voltages to
check & maybe find the problem.
Reason for diagnosis can be many. I could go into that if you wish.
Reason for the $20 is 95% of sets not worth repair are abandoned.
Then HE has to pay to recycle it. thats $10 - $30 around here.
Lastly how many $20 bills do you need to make $50 K a year after
15% SS tax plus state & fed taxes. You would have to gross at least
$70 K. And that dont cover shop expenses.
