Dead pixels in the LCD wafer; common issue with LCD televisions as they age. Replace the LCD wafer or consider purchasing a new television.

My Vizio TV has dark spot top left corner


Hi Brandon,
I am afraid that the dark spot in the screen is not repairable. Manage as long as you can or go for a new tv.

Hello, I have a 40" Samsung LCD flatscreen. My television has a 2.5" diameter black spot on the far left side about 4" from the bottom of the screen, Also we have a dark transparent band across the bottom...


Sorry Sir but your LCD TV got wet... it can be splash with too much water, an animal urinate on the panel, etc....
this kind of black spot is caused when the LCD Panel Terminals got wet, this terminals are located at the lower side of the LCD Panel.

I've noticed a dark patch in the lower right corner of the screen. Is this a bad panel or backlight? It's mostly visible in scenes containing blues.


Sounds like a backlight is out probably due to a bad inverter board. If you can see the spot when the tv is off its probably a bad lcd panel.

Dark spot on the right hand side of the screen


check make sure you didnt put your tv next to some thing that has a magnet in it such as speakers either from a radio or home surround sound system this will cause the problem and if its been sitting beside a magnet for awhile your probably not going to be able to fix it

It sounds like a couple of your back lights have burned out. I suggest taking it to a service center to have it looked at to make sure.

Big grey/black spot


Is it a fuzzy spot or an actual hard edged black spot?LCD televisions can have a loss of pixel display- most very small. Was the TV hit with something or dropped against something (the screen)?

OR Try this first:
Black box appears on the screen
• Closed-captioning might be on. Check the Analog or Digital Caption option in the Setup menu.

Please let me know if your problem is solved. Thank You.

DARK SPOTS!!!!!!!!!!!


Well depends on wether you what liquid you cleaned it with, because you are supposed to use the actual screen cleaner, if you use windex it takes off the finish on the TV and that may be what caused the dark spots. If not so I really do not recommed doing it yourself, it may just cause more problems, depending on when you bought the TV I recommed getting a TV repair man out there.
