SOURCE: I have a Haier Tv

Hi,

There is no dedicated audio board in the TV, the audio processing is one of the functions of the main board, also known as the AV board or motherboard.

I'm not sure whether your comment means you have a cable box or a direct cable feed and this is not the most technical answer, but I see this problem regularly with cable boxes and it's rarely a fault with the TV. Often the firmware/software in the cable box "crashes" and needs to be "re-booted". This is similar to what happens with a PC from time to time which is unsurprising as, essentially, these devices are computers.

I'd like to suggest that you reset your cable box before looking for replacement parts / numbers. Some cable boxes have a reset button on the front. Others simply need to be switched off and unplugged from the electrical outlet for a couple of minutes. If you're doing this, you may as well unplug the TV as well and "re-boot" it.

If this doesn't work, you should also try restoring the factory default settings on your TV:

1. Switch the TV on
2. Press the "MENU" button on the Haier remote to open the on-screen menu
3. Use the CH+/- buttons to highlight "FUNCTION"
4. Press the VOL+ button to open the FUNCTION MENU
5. Use the CH+/- buttons to highlight "Restore Default Value"
6. Press the VOL+ button to activate the restore feature

Please note: After restoring the TV to factory defaults, you will need to complete the initial setup again the same as you did when the TV was new.

If you have done all of the above and there is still no audio from the TV speakers, then there is a fault with the TV and you should post back to discuss options for repair.

Before posting back, please also try plugging headphones into the headphone socket on the back of the TV and check whether you have audio in the headphones. The headphone socket is next to the antenna connection socket.

Hope this helps.

Regards,
