A DVD player - an old one JVC RM-SXV074U. Sounds won't work when playing DVD.
First, I'm not a JVC tech, but I have worked on audio/visual system hook up and installations. This is the answer I gave for someone with a muted or garbled sound from DVD player:
*Check your audio cables (Red and white are audio) Pull out and re-seat them for a good connection.
*Check if your using 'other' audio methods like 'Optical' or the older multi-pin Video/audio combo plugs. Check DVD and TV cords and plugs for cuts or cracks. Replace if needed.
* If all audio from any source; Cable, Tape, DVD, etc. sounds the same then check the speakers (may be blown) Continue with steps bellow to find the specific problem.
* Go to DVD player and check audio options. set up for normal play. Only use other options IF you have the equipment (speakers) for that set up. IE; don't use 'theater' mode if you don't have theater speakers wired up for that option (usually a minimum of 3 to 5 speakers max.)
* Check the wires to each speaker for cuts, shorts, disconnection. Re strip wires as needed to ensure a good connection. Weak or low sound is an indication of a shorted or blown out speaker.
*Got to TV set up menu and check your audio options. If your not sure then reset TV to factory settings and perform an initial set up again.
* If you have good sound on regular cable and only bad sound on the DVD player then try another DVD player with the same cords. If your still using the older Yellow-Whit-Red cords then any similar video device should work on the same cords. Many VCR, Vid Cameras have the same outputs that can be used to test your TV set up. (Digital Cameras may have the same too.)
* Final, If your still having problems then check with the TV and or DVD vendor for advice.
* If this is a stand alone device (not hooked up to anything). DVD's use lazer (LED) to read the disk. Vid and sound are an intergrated signal. If you get vid then sound is there but may be garbled due to decoding problems. I had an exchange student here in US but found out that DVDs bought here won't play in her country (former USSR). I sent her home with a DVD player (walmart). If you are using the right player and DVD disk then your DVD player has a problem. Not much you can do other than check for dust. Cleaning disk may destroy the DVD as fix it, depending on the method used. Best bet is to check with your vendor for repair or replacement. Sorry, again. Not much to do with end products now days as it is cheaper to get a new device that to pay someone willing to fix it. (unless they are forced to by warranty. Usually the company will just swap it out. faster and cheaper.) Aloha, ukboy57
