Why do I have sound when I turn on my dvd and not when it is just the tv?

• Turn everything off. Turn on TV and Select dvd input (Source). Wait 10 or so seconds. Turn on DVD player. Works for me with similar problem. Good luck -

follow this steps and fix it. God bless you

1. Check if the TV and Amplifier (if connected) is turned on and set correctly.
2. Check if the TV, DVD player and Amplifier are connected properly.
3. Make sure the TV, DVD player and Amplifier volume are not set to Mute.
4. There will be no sound output during Reverse Play / Pause / Step / Slow / Search.
5. If the DTS soundtrack is enabled in the DVD Disc Menu, but you are using Stereo Analog audio, the sound will not work. Try switching the soundtrack to Dolby 5.1 or PCM mode in the Disc Menu.

I would look in the tv menu and see if the speaker audio on the tv have been turned off.

If the TV programs come's up with sound, then is possible that the TV set could be problem free. then cheek the system frequency if it need to be adjust from NTCS, PAL, AUTO MESECAM and so on. Cheek the DVD and VCR if they are in one of the following system settings and adjust the TV set to the settings at which the DVD or VCR is set to. Then you can also cheek if the cable is properly inserted, that is audio to audio and video to video. Nevertheless, if you have properlly connected your cables and set the system frequency to match with each other, and still no sound, then the TV could have sound problem.

Possible courses of sound failure in TV are as follows:-
1 RF stage
2 sound Ics or transistors
3 broken speakers
4 a break down resistor which supplie positive voltage to the sound curcult

Does your sound go thru the tv or a sound system ??? when ya turn tv off then on does it show anything like its coming on ??

While I could not find it in the manual, I found that you must
go to the menu, open Sound Options and set Speakers to "Fixed".

Note: If you turn off the Surround Sound or DVD player combination you must then go back to the menu and turn the speakers back to Televsion.

I have a sansui 19" LCD TV+DVD
I had to attempt multiple times turning the TV on to get a picture. The sound was fine. This kept happening when I would go to turn on the set the TV kept playing fine with picture & sound but after the 2nd attemts I turned it off & then tried to turn it back on which took multiple attempts, it kept playing for a few minutes then the picture went out but the sound was still there.
The set is not yet 2 years old.

Turn the sound down or off on the TV remote and only use the surround sound....

If you do not get result you can purchase one video rf converter. Rf converter contains one video input in yellow colour and two audio in red and white colour and one cable connector as outout. Connect dvd output to this converter and tune the program in which place you receive dvd signal.

Did you change your TV input to DVD as well?
