Samsung TV half the screen goes black or dark. ... My samsung 40" - 14 months old does this on the top half of the screen. .. ****** 12 month ...

If your TV has already fully adjusted in brightness set up?, and there will be no good picture results?...try to adjust the "SCREEN-Screw" at the flyback slowly. If the picture still dark'?. the picture tube has need to rejuvenate.

If a conventional picture tube type set it will have a high voltage transformer inside with a focus and "screen" control--in this case the screen needs to be adjusted up slightly.

Adjustment is inside the set so you have to have back off and be careful as high voltage is present when set is on (need it on to adjust the screen control just up a tiny bit).

try adjusting the contrast of ur screen. There is an Fn button in blue and contrast key in blue also. Press the Fn key and the contrast key together till u get the the darkness u want.

If this does not work, u need to get a technical guy to check the connection of ur display or u might need to replace ur display.

When the TV is on, if you look at the screen and can see dark images, then you will need to replace both the inverters. The inverters drive/power the back light inside the LCD to show the images. You may have to try and different channels and or inputs to truly see if you can see dark images while the TV is on. If you are hearing audio from a channel or an input then you should be able to see the dark images if just the inverters are bad.
If the screen is dead black without any dark images, then typically your LCD screen/module is bad.
If the TV powers up (power supply is good), you have audio and the remote will work with the TV (the main board is good), the only parts left is the inverters or the LCD screen/module.
I can get you LG part numbers if you need them.

maybe z board bad need replaced

Turn on the TI 83 enter 1234
1. press the <2nd> once; press and hold the <up-arrow> until you get the numbers as dark as you want. If you let up and press the arrow key again you have turned the function off. You must start over by pressing the <2nd> key then the <up-arrow> key and hold.

2. If the numbers are too dark; press <2nd> once and hold the <down-arrow> to get it corrected.

3. If this does not correct the light/dark screen condition you need to buy new batteries!

Hope you can follow my explination.

dark spot could be a faulty led. if you put a program on that is in white screen you should see all the leds light up the screen. dark spot will be were the led is not working. if on white screen and they all lite up but still dark around the area, it could be the lcd screen. and could be dying pixels. and try this video https://youtu.be/wlA2rcrAOCs

You may need to replace the screen - I can help you with that:
