Got in an RCA F36705 (CTC197) that is acting weird. Customer complains that the unit looses sync and channels. Went to customers home...found VCR on.Turned the VCR off and Picture cleared up....duh!!! Customer called back in about an hour and said it was the same. Went back the next morning and channels 2-13 were fine, but above 13 was not there. (Customer is on cable) Accessed the menu and there was no Antenna/Cable selection in the menu. I unplugged the unit for a few minutes and it still would not display the proper menu. The setup menu would appear, and I could access everything...everything except the Cable / Antenna selection. I loaded the "Big Ass Thing" up in my truck and took in to the shop...what do you know ... it works perfect there. The Antenna/Cable selection has returned to the menu and everything works fine. This unit is less than one year old so all the factory updates have been added at the factory. I went through the Tuner and resoldered all the grounds but it did not help. As I said...the TV 021 and the 0098 factory updates have been performed at the factory. I suppose the EEPROM is the most likely culprit, however everything looks Great at the shop. I just do not understand why the cable/antenns selection was not in the menu at the customers home and it appeared after I brought it to the shop.Any advice will be appreciated.
