Troubleshooting & Support for Dell W3706MC 37 in. LCD HDTV

Dell W3706MC 37 in..
what does the small TV HDMI connect to , I can not see or guess your connections at all.
a sound bar?, I am guessing , why not just say what you are attempting, in detail.

The problem that you describe is indicative of a failing or failed power supply in the TV.

A reputable technician would need to troubleshoot the issue with the appropriate test equipment.

Remove the stand, all screws from the back, then use very thin wide flat blade screw driver to separate the back from the front.

Hook an external Stereo Receiver (or surround sound system) up to the Audio Out jacks on the back of the TV... this should allow you to hear the sound again.
Hope this helps.

Yes,loud static usually comes from bad isolation of sound signal path so it's probably a frayed cable or a loose jack. Or if you're unlucky some parts inside have failed.

I do have sound board in stock.
