No tuning on tv

I have a RCA CTC169CK5  unit was dead I replaced the eprom and now I have OSD,?But I have no tuning or video in.I do have sound.Replaced tuner with another one still won't tune. Thanks for any help you can give. "Motron"

Was the eeprom a pre

Was the eeprom a pre programed one or did you use a chipper checker to do this or did you reprogram the eeprom by going into the service numbers?  You really should have the proper equipment to replace an eeprom unless you get a preprogramed one as they are only a couple of bucks more BUT you wiull still need to go into the service menu and do some touching up of the alighnments.  A service manual will give you all the info you need to adjust the service manu.  These settings I am leaving you is just and should be used as a reference and each set is differant. Good Luck and let us know how you made out with this TV set.
