I have a sony kdl-46v5100 tv and a sony ct260h sound bar. ever since hooking up sound bar my tv randomly goes black screen and no sound for about 3-5 seconds. i had comcast replace the cable box twice and still have problem.
soundbar is connected to tv by optical cable, tv does not support ARC so I cant use a hdmi cable.
Everything plays fine but the black out is very annoying.
Can any one help?
I tried sony but they have no idea.
 
If it's only connected optical, then no, it can't mess with the screen. That is either the cable box or cable signal cutting out, the hdmi cable is bad between them or the TV itself. Can you test with like your PC or something else to see if it does it on all inputs or devices?
