MY MAGNAVOX FLAT SCREEN TV HAS NO SOUND
there are so many reasons why your TV won't bring out sound. You need to
troubleshoot first, in order to get to the root of the problem, before a
solution can be proffered.
First, connect a DVD player to the TV, observe if there is going to be
sound. If there is still no sound after connecting the DVD player to the
TV, proceed to the next step. "The reason why I asked you to connect a
DVD player to the TV is to confirm if the problem is simply not from
the audio cord connected to the TV."
Second, get an headset, connect it to the earphone jack of the TV and
observe if there is going to be sound. If there is no sound, then it is
glaring now that your TV is having a defective sound card/IC that's why
it is not bring out any sound. (Note that connecting an headset to your
TV is optional because not all TV's has a space for headset). "The
reason why I asked you to connect an headset to the TV is to also
confirm if problem is not from the TV speaker. Though TV speaker
problems are rare but sometimes, the TV speaker might be defective or
the speaker wires may have loosed contact or cut into two, due to one
reason or the other. But if the headset doesn't bring out any sound from
the TV, then it is not so."
If none of the above seems not to be the cause of the problem, then the
above troubleshooting has confirmed that the TV has got a defective
sound card/ic. The sound IC/card of the TV has to be replaced for the TV
to bring out sound again.
To be honest with you, replacing or fixing the sound card/ic of your TV requires the ability or experience to do so.
Now, if you are convinced you can fix or replace this yourself, please
reply so that i can help you further. And make sure you troubleshoot
first, before getting back to me.
