This is a these are motel sets. I got 3 in, I resoldered all known
connections and replace the EPROM's, and all 3 Osc\mixer ICs.
The 2 in question came in for no channels from 2 to 50, after replacing
the parts and soldering, now the two have snowy pictures from 51 and above.

I replaced U3201, Q7403, and U7301.
T checked R7121.

Any help I will thank you for in advance.
