Try the first listed step before moving on to any others. Once you have solved your problem, do not perform any further steps.

Picture settings

Can’t find your recommended settings

  • Check to see if model was reviewed.
  • Click ‘Settings’ tab at top of review page.
  • If we did not review your model, visit our calibration page.

Screen is too dark

  • Increase ‘Backlight’ setting (‘Brightness’ on Sony TVs).

Colors don’t pop

  • Increase ‘Backlight’ (‘Brightness’ on Sony TVs)
  • Change 'Color Temperature' to something colder.
  • Increase the ‘Color’ setting.
  • Use the ‘Dynamic’ or ‘Vivid’ picture mode.

Picture skips/jumps

  • Disable motion interpolation.
  • Try different playback software/device.
  • Try different video file/disc.

Ball/puck disappears when watching sports
People/objects are moving too fast
Motion is blocky

  • Disable motion interpolation.

White objects/clouds too yellow or blue

  • Reset white balance & color space to default.
  • Change color tone.

Colors look wrong
Skin tones look wrong

  • Reset white balance and color space adjustments to default.
  • Use different color tone/temperature.
  • Use different picture mode.

Blacks look gray

  • Reset the ‘Brightness’ setting (‘Black level’ on Sony TVs).
  • Make sure source and TV RGB settings match.
  • Enable local dimming.

 Note: If IPS LED TV, blacks will always look gray.

 Note: All LED TVs have lighter blacks than plasma and OLED.

Brighter spots in dark scenes

  • Gently massage affected area with soft cloth to improve.

Note: This is a common issue, so if there is no improvement, only make a return if it is so bad that it ruins your viewing experience.

TV not displaying maximum resolution

  • In source menu, set output to your TV’s maximum resolution (if available).

 Note: No other fix. This is just the signal resolution.

Dark portions are pixelated

  • Enable noise removal settings.
  • Improve connection (if streaming) or source quality (if low-quality).
  • If neither works or is possible, you will need to cope with the issue. This is a common problem with low-quality media.

Grain on the picture

Note: Normal for movies.

  • For other content, enable noise removal settings.
  • Improve connection (if streaming) or source quality (if low-quality).
  • Reset color space and white balance settings.
  • Try different HDMI cable and different HDMI input on TV.

Picture looks out of focus

  • Disable motion interpolation.
  • Increase ‘Sharpness.’
    • This makes picture a bit less accurate.
  • Adjust the aspect ratio setting.

Note: Low-quality media often looks fuzzy, so if those first steps don’t help, the only solution is to watch higher-quality video.

Sparkles/banding appearing on screen after calibration

  • Reset white balance and color space adjustments to default.
  • Try new HDMI cable.
  • Try different picture mode.
  • Return, or contact manufacturer support.

Stuck pixels on screen

  • Connect PC to TV, use this tool to try and unstick.

No other fix. If many stuck pixels, return, or contact manufacturer support.;

Temporary Image retention

  • Watch regular content for a few minutes.

Permanent burn-in

  • No fix. Return, or contact manufacturer support.


TV not outputting sound

  • Make sure HDMI or audio cable(s) are securely connected to both TV and receiver/headphones.
  • Make sure TV is set to output audio to your source device (sound settings).
  • Make sure source device is outputting compatible sound (PCM, DTS, Dolby Digital are safe bets).
  • Try different audio cable.
  • See if other devices can play on receiver.
  • If receiver does not work for anything, contact receiver manufacturer’s support.
  • If receiver does work for other devices, contact TV manufacturer’s support.

Sound is delayed

  • If using TV’s speakers, try ‘lip sync’ or ‘audio delay’ on TV.
  • Set input to PC mode.

Apps & WiFi

Can't stream 4k video on 4k TV

TV channels look fuzzy

  • Make sure source device is outputting at least 720p.
  • Enable noise removal features.
  • Increase sharpness a bit.
    • This makes the picture a bit less accurate.

Note: It’s normal for TV channels to look a bit fuzzy/blurry, since they’re low-quality.

Remote and Power

TV turns off randomly

  • Disable CEC. 
  • Unstick power button on remote (if stuck).
  • Remove batteries from remote (to determine whether remote is responsible).
  • Otherwise, find pattern for the powering off, if one exists.

Questions & Answers

I bought a KS8000 and notice a sound delay. I found the audio delay in the settings and not sure what number to pick? Some other websites mentioned setting to 120. I was thinking 0.
If you are experiencing sound delay with the Samsung KS8000 then lower the audio delay setting would be better, increasing it will delay the audio even more. It also depends on your set up for this setting, try to decrease and increase it to match the voices on a movie or a tv show.
My Samsung Chrome laptop is 720p, but my E600i-b3's picture won't go down from 1080i. What can I do to make it look right?
You should be able to adjust the resolution being sent to the TV by changing the laptop's display or video output settings.
I have the Sony XBR65X930C. Purchased and professionally installed at the end of March 2016. TV was great at first with picture and sound. Last two months I noticed the sound volume is low and I have to turn it up to Level 43 to 48 to have decent audio. I did the "Picture/Sound Test" which I found under "Help" and the sound is great, real loud like it used to be when I first got the TV. At that point I have to turn it down from Level 43 to Level 25 but when I go back to which TV (I have DirecTV) I have the same low volume. I also have low volume when watching through my blu-ray or dvd players. Do you have any suggestions?
In the 'Sound Adjustments' menu, try different sound modes and make sure 'Night' mode isn't activated. Try to activate/deactivate 'ClearAudio+' too. If you can't pinpoint the problem after this, use the 'Reset' option under the advanced sound settings.
We're building a wall unit that will include our TV. I understand having a TV in a cabinet isn't the best idea due to limited airflow. What if we hide the TV behind doors in the wall unit and leave them open when watching TV and for several minutes after we turn TV off? THANKS.
It should be okay, since it will give time to the TV to cool down and also the TV won't heat up when it is turned off inside the cabinet.
I connected a MagicSing karoke unit to my Samsung UN55KU6290FXZA. The video and sound are present but there is no color and it is very pixelated and grainy. It's connected as "component" Red, White, Yellow. The MagicSing works very clearly on another TV connected the same way. Is there an adjustment I can change? I have just updated the software for the TV.
Change the input to "AV". Component uses five cables: Blue (Pb), Red (Pr), Green, White (L audio), Red (R audio). Composite (also called AV) uses only three: Yellow (video), White (L audio), Red (R audio). The Y input on your TV is used for either the Green of Component or the Yellow of AV, depending on the input selected on your TV. But Green is only the black and white information of composite video, so you only get a black and white image if Pb and Pr aren't connected.
While viewing TV, does frequent channel shifting has any adverse effect on the TV?

Thanks for reaching out!

No. You can switch channels as often as you like!
