Re: i ask for service mode for this model

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

Toshiba tv, model cf32c50 has a garbled sound issue.

distorted sound sometimes accompanied by buzzing is caused by detuned circuit in the SIF amplifier and sound detector circuit. a distorted sound alone is caused by a breakdown in AF amplifier circuit so try to change the sound ic since its the only options left. good luck!

No volume, but a faint buzzing noise.

check your speakers, speaker lines within cross checck with a audio out to an amplifier, if this works then your power amplifier is faulty. check for power failure to the amp from the main or sub supply.. also check to see the mode of the audio freg settings to the colour system.

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.

Take care.

Hello storymn,

This problem looks as if it can be you audio output amplifier stage of your TV. Also I would suggest shecking your remote and setup menu to make sure you are not in mute mode, this has happened at times. So your troubleshooting checklist is:

1) check the setup menu and remote to see if the TV is in mute mode

2) if you have the equipment check the audio at the output jack and the speaker.

3) unplug the set, take the back off and inspect the connections to the speaker.

*Only do the following if you have a background in electronics

4) Plug the set in and with a small audio amplifier check the output of the audio output stage if sound is present the check the circuitry on that path. If there is no sound the audio output IC or amplifier should be suspect in causing this problem.

I hope this helps,

Thank you,
