Mono DVDs play with no sound on specific TV

[Bix]

I've heard of this happening to other people but never a reason why or a fix. Does anyone have any idea?

Thanks!

Try disconnecting ONE of the audio output cables on the player, then report back.

Also, is the specific TV mono or stereo?

NOTE: If you don't have a problem with commercially made DVDs, the problem is likely the "mono DVD" itself. It was likely created with one of the audio tracks out of phase. On stereo TVs you'd hear audio, but it would be out of phase. On mono TVs you'd hear little or nothing at all.

Homemade DVDs dubbed from VHS tapes for archiving. Stereo TV. The TV sometimes has issues with stereo DVDs, too, where it mutes audio from one channel but not the other.

Can't check now, will later.

Try these things (in this order) and see what happens.
1. Swap out the cable.
2. Swap out the player.
3. Swap out the TV.

Have already tried all 3 in the past, and I believe it was in that order. Swapping the TV (same player, different TV) worked, as the other TV played the DVDs correctly. The others (different player and/or different cables all on the problem TV) didn't. That's how I diagnosed the problem as the TV in the first place.

Then I'm guessing the phase problem is on the TV. You might have to reverse the leads on ONE of the speakers.

I might be able to find an audio test signal to help determine if this is the problem. You'll have to burn it to a CD and play it in the player. Okay?

Sure, thanks.

Actually I found the test you need on-line. Download it and burn it to a CD, then play it in the DVD player.

Reversing the speaker leads might require some soldering. Then again, you might just be able to switch the connections.

You should also be aware that there is the possibility of receiving a severe electrical shock from your TV even if its turned off and unplugged. Please be extremely careful. If you aren't comfortable doing this, then take your TV to a repair shop.


Good Luck!!!

Thanks.

No way I'd mess with the guts of my TV though

Maybe you have a buddy who can do it for you.

Good Luck!!!!!!!
