It sounds as thought the main-board of the TV is arching or shorting out. This is due to a faulty component in the power section of the TV . It is about to completely go out.
The main board need to be checked for bad components.

Vizio model vx322 hdtv10a is losing sound and makes a loud humming noise and a poping sound every few minutes


Good day!!!!


That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

My TV is making cracking noise


Its the plastic cassing making the noise. If you press the tv together along the edges you will here a crack. Samsung and others did not use 99 cent padding between the plastic and the metal you need cushion padding. Its like not using a gasket or seal. Its a simple fix but the tv companies say its expansion.
