How To Fix Colored Squares On The TV Screen?

A ‘Samsung TV squares on screen’ problem is frustrating. However, understanding the cause and its solutions will help you get back to normal viewing without lengthy downtime. 

It could occur due to minor issues like poor connections to your satellite provider. The good news is that these problems have fitting solutions. Here’s a breakdown of what you need to know about these colored squares and how to fix your Samsung TV screen.

When you have colored blocks on your LED wall Samsung screen, you might be having signal issues.

Colored blocks on your Samsung TV indicate loose cabling or connections. Weak signals give intermittent service, thus breaking in steps when using your Samsung TV. Extra strong signal strength also causes colored blocks on your TV.

A change in its location could result in weak signal strength. Poor signals cause intermittency in the transmission. 

If you’re using an antenna amplifier, check on the power and transmission cables of the box to ascertain proper conditions and functionality.
