RCA CTC177AA

Troubleshoot the uhf section of the tuner, specifically the front end rf amplifiers. Possibly while repairing the solder connections a solder bridge was caused or a nearby component damaged. Also possible that the eeprom is severely corrupted from failed solder connections and a full tuner alignment is in order per the service manual.

Tag001 tuner signal generator or equivalent 125 channel cable signal generator. No, cable tv signal is not good enough to do it right as the cable companies signal may be considerably off frequency and no way to control the signal strength.

It could be the mixer ic. Sony CX something. It is the ic that stands up in the tuner assembly. Chuck
