Samsung led TV un60es8000 dark blotchy area on the upper right of screen. Most noticeable on greys,blues and blacks. The picture attached is the color most responsive to this issue (dark grey). Lighter colors you can't notice. Anybody ever see this issue before? 
This is caused by one of two things; a bad LED grouping (most common cause) either because the LEDs are bad or the power distributor fuse is blown and the group isn't getting power from the power supply unit. Or two: bad pixel group. But I'd check your backlight power supply for bad connections, blown fuses, or check your led groups for bad leds.
All connections are good. I can't locate the distributor fuse. Is it a tube fuse type? im assuming checking the LEDs I have to get behind the screen ?
Check to make sure your power distro unit which should be plugged into the power supply and the backlight cables are not damaged. You may have to remove the LCD display from the LED backlight panel to see if there is any other damage.
What's you opinion on it being the tcon board ?

I can't find anything on the Internet about this issue. Mostly vertical lines and I don't think this is the same problem
It could be, but usually dim led backlights are caused by power not being sent to the luster of leds. At this point I'd suggest taking it to a professional to be diagnosed.

possibly take a picture with cell phone then send it. That may work better. Jay

Do you have a center speaker near it? maybe move it, that is what I have done and it seems to have gotten better.

It is most likely the tube going out. Find some one to replace the tube if the TV is fairly new other wise it is going to be a trend. One tube now and another.. and so on. Ride it out as long as you can then go for an upgrade

What is the make and model of TV. If it is a Panasonic that has different colored spots such as pink, blue etc. Then you need t6o contact Panasonic as this is a memory reset that they have to perform on the LCD driver board. Other brands of LCD projection sets that have spots that appear all over the screen mostly on white back rounds are almost always dust that has settled on the LCD panels. This requires a technician to clean the LCD panels if possible.
