I highly doubt that. You know for sure if the amp ICs are good how? You still may have an issue with the b+ going to the IC's. the best way to service this TV set would be for you to get the service manual for this set and trouble shoot it from there. A service mode is a very dangerous place to go to to try and repair a TV set. You can cause problems that can make the set nearly impossible to repair. The service menu is not the fix all in almost every single case. the service menu is to do small alignments to the TV set. You problem is most likely a bad capacitor in the sweep power supply. good Luck

No sound from tv

first you have to check the volume settings tried to make some adjustment and also look the set up in the audio which in mute option. if the settings are ok, then with no any voice is coming the cause is either a bad speaker or a problem in the amplifier circuit. this time you will need to open the back cover of the tv to check the speaker using an analog tester to ensure weather it is worn out.if ok, next will be voltage checking at the amplifier ic if available, if it has 12vdc supply at the pin of the ic. you can check also burnt parts at the amplifier section. if you think you can not do the repair ust leave it to the trained tv repairman good luck.

Good picture no sound

tried to hooked up a powered pc speaker in the earphone jack of your tv unit.then make an volume adjustment in the tv, if you can get sound there, the cause is will be worn out speaker or wiring connection. but if can get sound there their might have problem in the sound amplifier, check for bad audio amplifier ic or an open resistance in the audio section.

I cannot get any sound from my wega KV-24FS120 sony. Sound does not come from TV speakers themselves. I tried MTS and all the audio functions. What to do? Demian

Hi,There are three cause of no sound,ethier the problem is in the speaker,sound driver or output and from the audio setting.First is check the setting, that you already done that what you sad.Now check the speaker if good or not,Use analog or digital tester to check the speaker if good or not or test the speaker to the other amplifier to identify if good or not.If the speaker is deffective replace it and if the speaker is good the problem is in the sound driver.Maybe the sound output ic is deffective or no supply.Thats why it is needed to troubleshoot and repair the sound circuit section of your television.Thanks

The speakers are not working. if i turn up the volume, I can hear static noise, but do not get any sound. tv speakers are on. I played around with the audio settinds and all the different hdmi ports,...

There are two possibilites for this fault. The first one is, damaged speaker voice coil and the second one is damaged audio output IC. To confirm it you have to open your TV. Speakers can be checked without removing them from the cabin fittings. Check them with the helap of a multimeter; set in OHms range. You can alos check it with a standard torch cell also. Connect the two terminals of the torch cell to the two terminals of the speaker [intermittantly, not constantly]; will produce a 'thumb' sound; if the speaker is good.
Connect the 'audio out socket' of the tv, with any other audio equipment, and listen whether there is sound form the external audio equipment, like amplifier or so. If there is sound from the external audio equipment, and no sound from the internal speaker of the TV, and the speaker is good, surely the 'audio output IC' of the TV is damged and should be replaced. OK.

No sound,but good pic.everything else works fine.(toshiba 57hx94)


• Check the antenna/cable connections (see Chapter 2).

• The station may have broadcast difficulties. Try another channel.

• The sound may be muted. Press VOLUME.

• If you hear no sound, try setting the MTS feature to STEREO mode (page 81).

• Make sure the SPEAKERS function in the AUDIO SETUP menu is set correctly (page 83).

• If you are not receiving a second audio program from a known SAP source, make sure the MTS feature is

set to SAP mode (page 81).

• If you hear audio that seems "incorrect" for the program you are watching (such as music or a foreign

language), the SAP mode may be on. Set the MTS feature to STEREO mode (page 81).

• When using an external audio amplifier, if you connect the amplifier to the VAR. AUDIO OUT jacks, the
volume of the TV and amplifier must be set above 0 or you will not hear any sound (page 20).

No audio on model at1308 good picture but no sound....thanks mel


there is no sound on your TV because the sound IC is faulty.

You can open the TV an read the sound IC with a meter or just take the TV to a repairer to fix the problem for you once and for all.
