On my TV the fault was caused by the Power supply IC providing power to the audio IC.
Measure on the +15V and -15V test points with a voltmeter to check if your problem is the same.

I have perfect picture but no sound??


Many Mitsubishi TV have an audio mute button on the back of the set. It is near the audio out RCA connector and is used to disconnect the internal speaker when an external speaker is used. Just press the button and the internal speaker will work.

No Sound


Could be a sound problem in the set but first:

Are speakers for some reason switched off in menu?

Is (some have this) internal/external speaker select set to external?

Is volume on SET OR A BOX muted or turned way down?

Does the set have sound with a DVD etc. hooked via a rear audio/video input?

No sound on monitor tv. Does it have internal speakers or does it need external speakers hooked up to it? Also, i need help configuring it so it will play audio


Set indicated here has speakers and may have a slide switch on rear to select internal or external speakers.

Also in menu look to see if speakers are switched off.

Your internal speakers may be shut off, go into your menu, go to sound, look for an internal or external audio setting. If internal make sure it is on, if external make sure it is off

I hooked up my stereo amp to my external speakers that were also still hooked up to my tv. now I don't get any audio from my tv just a high pitch sound. Is this an easy fix?


Hi, I can help. It sounds like the TV internal speakers were turned off so that the only speakers to have sound were the external ones. Go to your menu and find the sound area. There you can tell the TV to send sound to the internal speakers once again and not to external.

No volume


On the back of your set there are 2 switches that tell the tv whether you are using the internal speakers or the external speakers.
Make sure the switches are set to internal so the speakers in the TV receive the sound signals. If they're set to internal maybe the internal speakers are bad. Set the switches to external and hook up external speakers to the speaker terminals on the back of the TV. If neither setup works then it sounds like an output transistor or related parts.
