I need help - Electronic Circuits Projects Diagrams Free

I have a Telefunken model TTV-210 TV. Picture is perfect but no sound - only noise and sometimes radio station. I have replaced everything related to sound - even swapped components with a working TV (same model). It seems to be a setup problem - cannot find sound settings in the menu.

Cable/Antenna setting?

Not sure what you mean. It uses external antenna. It has a setting for TV/AV. When DVD player or TV game is connected - sound is O.K.

Sounds like an internal problem. If the receiver works with external audio sources only, then the fault could be an electronic switch. Probe the interior ( carefully!) with a signal tracer around the speaker wires, including the external source inputs. Without identifying how the audio is switched, I can be of no further help.
