Hello, Sorry you're having problems. The Samsung set cycling itself On and Off with the light flickering like this is an internal hardware fault occurring. More specifically it is the "Mainboard" in the set which is failing, and ultimately requires replacement to fix the issue. That said, there are no pushbutton fixes for this. If you're looking to repair the set yourself, please respond back with the full model number off of the back of the TV and I will look up a source to purchase the Mainboard for you.

Alternatively, if this is not something you're comfortable trying to tackle yourself, a shop will typically charge between $200-$300 parts and labor to replace the Mainboard (depending on model and size) and can be located using the following link:

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