Your right, I misspoke, Miswritten? but you have to realign most sets or some station will be snowy. If you don't get the high cable stations then you may get by without realignment Phillip R Hull STET phil245@xxxxxxxxxxxxx ----- Original Message ----- From: "Kevin" <kevintv@xxxxxxx> To: <techassist@xxxxxxxxxxxxx> Sent: Wednesday, January 22, 2003 4:15 PM Subject: [TechAssist] Re: Need refresher on RCA EEPROM replacing...] > > I can buy preprogrammed generic eeproms.
