TV RF Section Failure?
My RCA TV appears to have "lost" some channels.
Most channels are OK. Cable Channels 48, 49, 50 are wiped out. Channel 65/66 experiences intereference from over the air channel 14.. Other channels that I know I should get seem to be ok, including those that might be effected by other OTA channels. RCA input video is ok so I surmise it's an RF problem. Here is the RF section: http://www.mailsack.org/tvrf.jpg Is there a way to open it, service it, replace (guess I could desolder it), tune it, etc? Thanks! __________________ Note: To reply, replace the word 'spam' embedded in return address with 'mail'. N37.3 W122.0 |
