I have a 37” dell tv with static & popping noise. Model no. W3706MC. The picture is perfect. Would this be problem with Main Circuit Board? You can reach Me at [email protected]. Thank You!

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.

That's being specific lol I have the same board what other info do you need?

i just fixed this same problem on same model - its the main board on the back of the tv - find the part number off of the main board (the board with all of the av input jacks) replace it and that will solve your problem.

thanks,

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.

you will need to check you AUDIO SETTINGS on the TV and set it for HDMI

your mainboard needs replaced from within you engine component located in the rear part of the unit. its the boad with the most inputs. google the board id and see if u can find a replacement.

Sounds like a bad video board. No easy way to fix a bad video board. It needs to be replaced. That is why the repair shops will not fix it; they do not stock video boards for all models. And it is a pain to track one down all of a sudden. Once a warranty is up, you are running on bonus time. Electrical components have a definite lifespan. It is possible to recover some money by selling it "as-is" online somewhere. You could get 200-400 for it broken, pretty easy I suppose.

I do have sound board in stock.
