Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should trouble shoot. Contact any service technician. The circuit will differ with models and versions.

How to fix vizio tv


The backlight is LED and not likely to fail, it is most likely the main, modular power supply causing the problem.

Look inside 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.

Replacements can be had but unless a couple of parts are added (by the maker or a smart tech) the same failure will eventually occur.

Why won't Vizio Tv come on?


Most likely it's a capacitor fault.

Google "Capacitor bulge" and then search Youtube for your make and model to see if anyone has done an instructional video. You'll need to be comfortable dismantling the unit and be able to use a soldering iron. If this isn't you then take it to a repair shop.

Vizio VO47L FHDTV10A black screen no light


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.

?Check the cables, connectors and connections.

Take it to a repair shop.

Vizio GV42L LCD TV screen black when turn TV on first time


If you are using a set top box this might be caused by turnig the box on at the same tie as you turn the tv on or slightly after you turn the tv on.  If you are using compnent or HDMI inputs the set needs to see the signal as it is turned on to know what formt the signal is in.
