VIZIO E65X-C2 Backlight issue
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:
- Make sure that all of the connections between the TV and the wall outlet are secure.
- Check the TV's backlight setting and make sure it is set to the optimal level for your viewing environment.
- If the TV has a local dimming feature, try turning it off to see if it makes a difference.
- 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.
Vizio M55Q6M. I have a slight dark area top left corner and bottom right corner is it a back light problem please?
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.
Why is my LED tv intermittently flickering
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.
TV half snow static, half perfect
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.
How do I diagnose which board I need for 4k TV that powers on but the screen is black?
With the TV turned on, press the menu button and shine a bright flashlight on the screen at a shallow angle (about 20° from parallel to the screen). Move it around - if you can see the menu or other material where the flashlight is pointing, you have a backlight failure. This may be either in the power supply, or the backlight itself (sadly, with LED backlights, it's usually a blown LED).
How do I know what board is causing vertical lines?
It's actually the panel that's bad, not the board, one of your clock lines are shorted but it can be fixed with a piece of scotch tape by masking off the correct clock line, there should be 8 of them and it will give a decent picture just using 7, there are some youtube vids that describe how to find the pin to block if you want to dig into it.
D65u-d2 black screen diagnosis
Hi,
I would have attempted a system software update first once the screen went black. I would also disconnect all accessories. Then, if still failing, I would schedule a repair with a tv repair shop because it's dangerous to deal with internal portions of the tv as a consumer.
Thank you.
