Vizio 55-inch E550VL 1080p 120Hz LCD Television Refurbished Questions & Answers
May have had a power surge. Now Visio light comes on, but no sound and black screen. Can it be fixed or too far gone?
Not 'too far gone' yet but the nature of the failure points to the modular switched mode power supply,
Look for a block assembly with larger components and several connectors that is bolted onto a larger panel.
These are purchased from other sources, not made by Vizio.
Look into the guts of this assembly for cylindrical components with plastic foil and an aluminum top, mostly mounted vertical to the board.
Examine the tops of these for any dome-like appearance; this is a sign of failure since these should be flat.
They are inexpensive (one reason they fail) and this failure can be prevented by spending another dollar or two in the manufacture of them.
Vizio remote control won't work with tv..
Just unplug the TV from the power outlet and hold down the power button on the side of the TV for 15 seconds. Doing this drains residual power and can clear up odd issues. Then plug the TV back in and power it on. Test the remote again to see if it's working.Mar 10, 2015
