Your done, replace the TV before you bury yourself in parts cost and labor.

1. Make sure the video cables are properly connected. The cables that connect the DVD player to the TV should be securely plugged into the correct ports on each device. Double-check that the cables are not loose or damaged.
2. Check the input source on your TV. Make sure the TV is set to the correct input source that the DVD player is connected to. For example, if the DVD player is connected to HDMI 1, then the TV should be set to HDMI 1 as well.
3. Check the TV's settings. Some TVs have a "picture in picture" or "picture by picture" feature that may be turned on, preventing the main picture from showing.
4. Check the DVD player's settings. Some DVD players have a setting that controls the aspect ratio of the picture. Make sure this is set correctly for your TV.
5. Check the TV and DVD player compatibility. Some TV's are not compatible with older DVD players and this could be the reason for the lack of picture.

What board are you calling the "Video" board?

There could be a few potential causes for the issue with the color on your Vizio M3D460SR TV.

• The first thing to check is the cable connections, ensure that all cables are securely connected and that there is no damage to the cables or the ports they are connected to.
• It could be an issue with the TV's settings. Check the TV's color settings and ensure that they are set correctly.
• The problem could be with the TV's T-con board, which is responsible for the image processing and color display. If the T-con board is malfunctioning, it may result in a lack of color or color distortion.
• Another possibility is that the problem is with the TV's main board, which controls all the functions of the TV. If the main board is malfunctioning, it could result in a lack of color or other display issues.

It's hard to say without further troubleshooting, but it's likely that the problem is with the T-con board or the main board. If you're not comfortable troubleshooting, it's best to contact Vizio customer service for further assistance or contact a professional to take a look at it and provide a resolution.

There might be a connection that is loose and not securely connected to your TV.Or the power supply cord is starting to go bad.For a power cord that is not working with a TV you will need to buy a new TV.

On a TV this size changing the strips is going to be quite difficult to do without damaging the panel, you positively need 4 suction cups (can be ordered from shopjimmy.com) and 2 people to remove and replace the screen, if you try to do it without them you will most likely damage the panel and the set will not work once you get new lamps in. Also you most likely will find 2 sided seal tape around the bottom of the panel (under the panel and on top of the panel holder), to keep screen cleaner from running down the screen and damaging the panel boards.To get the front frame off, they use clips that are part of the frame but there are a few things to remove before the front frame, start by removing the speakers and any metal pieces on the bottom back, there vary from model to model but generally include the metal leg holders, tcon board cover, if it has a tcon board, ect, you have to get at the panel boards before flipping the set on it's back, once you remove the front frame you won't able to flip the set over without the panel partially falling out and damaging it, it's much easier to remove these parts before laying the TV on its back, also remove the panel board ribbon cables when the TV is laying on it's face. Once you have the set on its back, take a screwdriver and and put it between the outside frame and metal inside frame and move it while pulling down on the frame, and you will feel it release, you will find a clip every few inches, just take it slow or you will break the tabs off then the frame won't stay on once it's replaced, good luck with this adventure, changing them for the 1st time can be fairly hard to do, also look at the bottom of the outside frame as some vizio model sets have small screws along with clips.

First place to star is with what is called the TCON board. You will have to take the television apart, locate and replace. Some of those require that you upload the firmware to them before it will work again. This is the most logical starting point I can give you but may not be the full problem. If I were to put a percentage on it, I would say this is the problem on about 75 percent of the problems with the same issue.

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.

Do you have backlights?

Hi, the accessories replacement was a smart move. Please attempt to run a channel scan before updating your tvs firmware. Otherwise, I would run a factory reset on the tv and watch for the display-color issue again. Thank you.

It sounds like you may be experiencing an issue with the color processing board in your TV. This is the circuit board that is responsible for receiving the video signal and generating the colors that are displayed on the screen. If you are experiencing issues with the color on your TV, it is possible that this board is not functioning correctly. If you would like to try replacing the board yourself, you will need to locate the correct board for your TV model. You can usually find this information in the service manual for your TV or by contacting the manufacturer.

Never heard of the controller and neither has Google, so that doesn't bode well. The codes on the other hand are easy. You should read this though. https://www.fixya.com/support/r29872378-universal_remotes_no_facsimile_remote

It sounds like your Vizio TV may have a backlight issue, which can be caused by a problem with the LED strips or the backlight driver board. To determine the cause of the problem, you will need to perform some troubleshooting. Here are a few steps you can try:

1. Make sure that all of the connections between the TV and the wall outlet are secure.
2. Check the TV's backlight setting and make sure it is set to the optimal level for your viewing environment.
3. If the TV has a local dimming feature, try turning it off to see if it makes a difference.
4. Check the TV's picture settings and make sure they are optimized for your viewing environment.

If these steps don't fix the problem, you may need to replace either the LED strips or the backlight driver board. To determine which component is faulty, you will need to perform some further troubleshooting or seek the assistance of a professional.

It is possible that the issue you are experiencing with your Vizio M55Q6M TV could be caused by a problem with the backlight. The backlight is responsible for illuminating the display on the TV, so if it is not functioning properly it can cause uneven lighting or areas of the screen to appear darker than others. Other potential causes of the issue you are describing could include a problem with the display panel itself, or an issue with the TV's software or firmware.

Hi Jeannette, it would be VERY rare for a power cord to cause a set not to work. Is the set totally dead or do you get the standby lamp when you plug the set in?

The cables could either be loose or need to be replaced for your TV or the connection ports are broken. The LED lights or the T conn board could be causing the TV screen to flicker.

The T-con board sounds like the most likely issue on your Vizio. Typically if the video signal is being sent to the T-con, then the t-con resolves it into the format required by the LCD screen. In this case since part of the video is fine and the part is snow/static, I would suspect the T-con. Is it perfectly half the screen? Typically there are two connectors out of the t-con to the LCD, so one if one of those is loose or going bad, then that may be the issue as well.

Back - light problem. 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. http://electro-medical.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

go to setting and factory reset when it comes up it will ask you to scan channels analog digital or both click both
