Hi


Thanks for using FixYa. From what you have described it seems that you might have a backlight and/or an inverter board issue with this TV set. It could also be due to the inverter circuits for the backlights. The inverter is the power supply source for the backlights. There could also be a screen driver problem; if it is then you have to change the entire inverter board. All this is only recommended if you have some kind of expertise for checking the internal circuitry of the TV as these units have high voltages running even when the set is switched off. The cost to change the inverter board including labor would be around $250, if you get this done by a professional. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks

    Yeah right, it seems to be a bad component on the inverter board. You can open the back of the unit then blow off the air and check for the inverter circuit board. Please do accept the solution if the issue is resolved or post a comment for further assistance.


    Thanks

Dusting it out real good will make it work again, be careful not to touch the circuit boards with metal objects. I used a shop vac with a bristle brush, nice

Could be the capacitors going or have gone out. This is a common problem with Vizio TVs...including mine recently. Check out YouTube for tutorials on how to change the capacitors.

TV has no picture, no sound just the VIZIO logo light is on the screen.


Did you check out the power supply for proper operation since both the audio and video are gone? If PS is good then the problem may very well be on main board.

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.

Black screen with sound


My 47" LCD Smart T.V. was working fine last night. I got up this morning and I have sound but no picture. The VIZIO icon lights up as usual but I get no picture, only sound. From the time I turned it on, nothing appeared on the screen. I have already tried unplugging it for a while and still nothing.

Vizio VP50 has sound no picture


If this is an LCD TV, show a flashlight on the screen from a safe distance and check whether you can see the picture. If you can, the backlights or its circuits have gone bad. If you cannot, the TV needs attention of a qualified service technician.
