Offhand, this issue isn't related to the cable box in any way- and it's the TV itself that has a problem. What is the full model number off of the back of the Samsung and how OLD is it?

Please send a reply back to proceed.

Expert:  Aric replied 2 months ago.

Thank you. Unfortunately these symptoms are caused by a faulty Mainboard in the TV, and requires replacement of this board to fix the issue in most cases.

However it's worth it to try a hard reset, as sometimes the processor in the TV can simply have locked up.

The first thing you would try, is disconnect the set from power, then press and hold the power button on the TV itself (not the remote), for 10 seconds and release. Then plug the set back in, and also check that the power cord is connected tight at the TV as well. Press power once, and see if the set powers up normally. Try this procedure up to 2 times, and please let me know what happens.

Were you able to try those steps and are you having the same problem??

Expert:  Aric replied 2 months ago.

If you're still having the same problem, then unfortunately this indicates the set's Mainboard has failed and needs to be replaced. This is a "plug and play" part- meaning no soldering or special tools are needed to replace it. Only a screwdriver and about a half hour of your time. If you want to fix this yourself, I will NEED the FULL MODEL number off of the sticker on the back of the TV to look up that part for you.

Alternatively, if you're not comfortable with this type of work, then at a shop this is $250-$300 parts and labor (depending on which model 60" Samsung you have). If you'd like to inquire on repairs, or seek a 2nd opinion, you can use the link below to locate a shop in your area if you'd like:

Other than that, I'm sorry for the bad news and wish there were a quick fix.
