Everything works normally if watching cable but if I change input to DVD there is no sound now (recent problem). It seems to be the RCA audio inputs that aren't working (no sound from DVD or VCR). Tri
The phono-sockets, aka RCA sockets have a female pin in the center.
Sometimes, these tube-shaped metal pins become stretched or oxidized, causing loss of contact.
The easiest quick-fix you can try is to briefly squirt the socket and cord-plug with Servisol or similar evaporating contact-cleaner, then repeatedly twist, push and pull the plug in and out to 'scrub' the potentially oxidized surface.
If that doesn't work, option 2 is possible if your sockets are open at the back of each socket, ie: not sealed / molded types.
Unplug power, remove cover, locate phono sockets.
If center pins can be seen from rear, try crimping slightly with needle-nosed pliers, or use a dart point or pen-knife to 'push' the pin-barrel slightly closed.
Make a test-cord with plug removed, connect an AV audio source temporarily by hand to the suspect socket's connectors, observing polarity of center and screen.
If molded plugs are suspect, try levering pin-barrel more closed from front end if possible, or if totally kaput, renew sockets.
