Model PN60F8500AF Turns Off and Back On

[Cable2]

My tv randomly has a dial tone then turns itself off and then turns itself back on.  What could it be?

Hey there! I can understand how aggravating this can be and am happy to assist you! The following link provides some troubleshooting for your TV power cycling: https://www.samsung.com/us/support/troubleshooting/TSG01108742/

However, when TVs start making dial tones or screeching noises, this is normally a sign of a main board failure and we would recommend having a service technician look at the unit to diagnose it further as there may be additional things that need to be addressed
