Not soldering these grounds will absolutely corrupt eeproms. I remember changing an eeprom in one of these in warranty for no audio. Two days later it was back. These chassis were new at that time and we had little experience with them. A call to RCA about the failed eeprom was to solder the tuner and heatsink ground tabs. RCA issued a "goldenrod" about this about a week after I ran into this.
You could solder the grounds and then get into the service menu and reset the vert height and centering. Normal values are between 0-63 IIRC but sometimes we'd see values that didn't make sense, like numbers in the hundreds or with letters instead of digits.

Hey John. I turned it back on and it's running normal again. Should I go ahead with the grounds?
