My TV doesn't have any sound with its cable. The

Sounds like a bad timing control board...Tcon...that generally causes picture issues when there is sound.

there is sinal interferences from laser products pc mobile transmitters or video games get high quality vcr and cable tv cables move or switch off any video games cd players energy saving lamps or pc and microwaves n motors like pumps change the position of installation of cable and antenna to avoid path of interference

If the set was purchased in the USA it has the USA format which is NTSC--unless the signal is NTSC picture will be in black and white and no sound.

If the signal format there is PAL OR SECAM you will need a converter that takes that and outputs NTSC for the set to work properly there.

Make sure if you have a set top box (cable box) that the volume is turned up in that.

Pl checked Cable Signal level with db meter it should be 50 to 60 db.in your cable pin.or you can attach any other small TV and check picture quality.Most of this is your cable problem.

Your TVs tuner tuned a little off frequency. It could be as simple as having cable box on where you have good picture but fuzzy sound, use the TVs remote to change the channel and then change it back to proper channel. If that doesn't fix you may have wrong tuning type selected in channel set up menu.

I have sound on video 2, and when on a static channel but not on the usual channel 3 which is TV. Just stoppen working one day and cant figure it out... Please help!

If you have static siugnal, sure TV is not dead.

Check the aerial cable, ensure it is well plugged in and getting signal.

If you are using a receiver box, check cables to TV and receiver (freeview, sat, cable etc.), try setting channels on receiver again, if it does not work but you get static, then either the cables or receiver are defective.

Test the TV on standalone , connecting it to an external antenna.
Tune again the channels, and save the preset.
If still no signal then the antenna socket on the TV may be defective.

Try using the TV with a DVD.

If you can watch DVDs, and TV is not keeping channels preset, and you tried all the above, at this point htere may be a fault in the tuner card inside tv.

Call the phone number listed on tv user manual to get support, and eventually repair it.

check to make sure all connections are tight if that does not work the EEPROM chip might be bad

Hi,
Check in the menu to see if the audio is on SAP. If it is change it to Stereo. Hope this helps
