White vertical bars on both sides of the screen

Since yesterday, I’m suddenly seeing two white vertical bars on both sides of my screen when playing media from my WD live player. Irrespective of whether it is media files or netflix I see this. This effectively takes away 1/3rd of my screen. How do I get rid of this?

Thanks

You kinda need to give more details than this if you’re looking for a fix.

1.) Try different HDMI cable
2.) Connect device to a different monitor to see if the issue goes away.
3.) Were there settings changes you made to the player directly before you noticed the issue? Trace back and undo them if you can.
4.) Were there settings changes you made to your TV/Monitor directly before you noticed this issue? Undo them.
5…) Factory reset
6.) Downgrade to 1.04 FW if on 1.06.
7.) Contact WD tech support via phone
8.) Return if under 30 days
9.) RMA
