Possible causes |
Signs to look for |
What to do |
|---|---|---|
Malfunctioning set-top box |
Has it been a while since you last rebooted your set-top box? |
Your set-top box may just need a simple reboot.
|
Loose connection |
Does the picture rapidly cut out to black or a snowy screen and back? |
Check that each connection is pushed in as far as it will go, and tighten the connections with your fingers:
|
Faulty set-top box |
Does the picture flicker to a black or blue screen? |
You could have a bad set-top box. Contact your cable or satellite provider about installing a new one. |
Rigid cables |
|
Try replacing your rigid cables with more flexible ones. Wall-mounted TVs may benefit from using cables with 90-degree connectors. Occasional TV picture loss can sometimes be a side effect of overly rigid or thick cables. |
Failing backlight |
Does the audio continue to function as your picture fades in and out? |
Arrange for a TV repair person to replace the lamp—before the TV flickering stops and all you see is black. Note: Impending backlight failure may also be indicated by a TV that has sound but no picture.
