I would verify the voltages on the power supply board first because an improper voltage to a circuit board may make that board look bad.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Hello Michael, for what you are saying, it is very possible that the rear lighting of the LCD panel is not working, usually two or three LEDs are burned, these come mounted in strips
To make a good repair, you have to change all the LEDs or replace all the LED strips
I give you the link of a video of another Vizio TV model, which shows you how to replace the LED strips
I hope you can solve the problem
Greetings Franco Dosil

Hola Michael, por lo que comentas, es muy posible que no esta funcionan la iluminaci?n trasera del panel LCD, por lo general se queman dos o tres LED, estos vienen montados en tiras
Para hacer una buena reparaci?n, hay que cambiar la totalidad de los LED o sea reemplazar todas las tiras de LED
Te paso el link de un v?deo de otro modelo de TV Vizio, que te muestra como reemplazar las tiras de LED
Espero que puedas resolver el problema

It could be many things but i would start with the power supply board with the power problem, could just be bad capacitors, which is so common on tv and monitor power supplies.

However, the colored lines could be an even worse sign that the mainboard failed if the power supply output voltages are good.

I would start with checking the voltages from the power supply board, if your lucky the voltages are labeled at one of the connectors. If all the voltages are what they should be, and you don't see any bulged capacitors, then its most likely a failed mainboard. Not much you can do to repair them, just have to find a replacement, which in itself can be difficult!
