Check the speaker/s first. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis.

I have a 27" Toshiba television, I'm having problem with the sound. I've changed the sound output but nothing happen. Please help.


Hi
Jennifer Castillo


Here are some possible locations where to look to :
( Since I have no model for your TV or additional details which you have
replaced)

a) switching IC ( these IC switches the TV to Audio Video In)

b) muting circuits ( there could be one )

c) Check the audio out coming from the Jungle IC (also unknown)

d) check the supply lines of the audio IC (could be +12V, typical)

e) Check the headphones out (if available)


If there is an audio Out, connect an external amp to test.

If audio is present , check again for solder joints to main amp.


Use these as a guide in troubleshooting :

Computer Speakers

Your input is the Jungle IC, search on line for datasheet about it.

same with your Switching IC and Audio IC.


On some audio IC, volume control is included on it.

Let us know what you find or needs further assistance.

Geepas DVD player not reading it's shows no disk


This is a problem in the laser pickup, try a DVD cleaning kit and follow instructions, if this fails it is far cheaper to replace the player.

Great picture, no audio. no audio on audio out using computer speakers either. no audio period,dvd,games,etc. my brother tried to plug in some reguler speakers to the audio out, they were 8 ohm.


Hi,


The problem you are experiencing with your TV is as a result of a bad sound output IC(integrated circuit),the sound IC generates and transmits all forms of sound produced by the TV,since its bad no form of sound can be produced from the TV.

The solution is to replace the sound IC of your TV,it is normally located beside the screen IC,depending on your brand of television,it can be purchased from any electronic part shop close to you .


Thanks and take care..

I can not hear any Audio


Hello,

the sound IC is bad, that' why you cannot hear any audio from your TV.

You need to change the sound IC to hear audio from your TV again.

Good luck

Sanyo DS35510 35" has picture but no sound. Checked all audio under menu section, turned both tv and cable up really loud, made sure both cable and tv wasb't on mute and still no sound.


Hello,

You may have a malfunctioning audio output IC. I would suggest checking the input to the IC and seeing if you have an audio signal at the input. If so then the output IC is defective, if not continue checking the stages of audio going back from the output IC.

In addition check your speaker connections, and internal cabling.
This can cause this problem also.

Thank you
