Sounds to me like you need to do a complete tuner alignment then. I hope you
recorded the eeprom values before replacing the chip. Have you done one of
those before? Might be Y7401 off freq. Check C7507. Also Q4106 possibly
shorted, R4132 open and R4130 open. Replace L2302 at end of T chip. Repair
trace from 12V to collector of Q7601 SAW AMP. Check U7301 see if pin 1 has any
output.

I am a tech and I'm sorry my message wasn't clear I did the re solder and
replaced the epprom #218400 My problem is the set can't leave the house and
I have no prints for RCA or GE. There are no bad connections I was hoping
someone had a tech-tip on this problem other then connections and EEPPROM.
