It sounds like you may have a problem with the video signal on your Vizio 55 inch flat screen TV. The fact that the TV turns on and has sound, but no video and vertical lines on the screen, suggests that there may be an issue with the video processing or display.
It could be a problem with the T-CON board, which is responsible for the video signal processing. It could also be a problem with the LCD panel itself.
It's also possible that there's an issue with the cable connecting the T-CON board to the LCD panel, or a problem with the software on the main board.
I recommend consulting the manual of the TV or contacting the manufacturer for further assistance. A professional technician should be able to diagnose and fix the problem.
It's also possible that the issue is with the mainboard or the T-CON board is not compatible with the TV. Thus, it's best to check the compatibility of the parts with the TV before installing it.

Tv problems lg and vizeo

Power Issues Troubleshooting
*NOTE* LG & Vizio TVs must be plugged in for 5 minutes before it will turn on*
1. Inspect ALL Ribbons and connectors. Any tears or bad connections between boards must be replaced FIRST
2. If you have any of these boards, it should be the first board to be replaced
A) T-Con Board - Video Problems (No Video with standby light on, audio but no video, grainy, distorted, or color problems in screen)
B) X or Y Buffer Board (Plasma TVs only) - Standby light is on but no power
C) Backlight Inverter / LED Driver - No Video with standby light on
3. Main Video Board
- Standby light is on but no power
- Either video or audio does not work (if no T-Con in TV. If audio but no video it is T-Con)
4. Power Board - No power AND standby light does NOT turn on. If standby light is on try other boards above
5. Panel - No power, distorted picture, lines, slow motion, half screen, faded in / out. Panel problems are usually not worth replacing the panel.

I have a 55 Vizio 3D smart tv. This picture color fade in and out to the point that I cannot watch tv. I this a problem with the main board?

Hello Patricia,
  • There is a loose soldering connection in the Main Board. That happens because the components on the are generating a lot of heat therefore melting solder connections.
  • Stop beating on the TV's back, that only makes the problem worse.
  • Take it to a shop.Or if you are a tech, try locating the loose connection(s) and solder it back.
  • Also check your Warranty Period, It may cost you 0$. Call Vizio if you still have Warranty on the TV.
Here is a link to Vzio Supoport.
Good Luck,
JP
