Samsung Model UA40J5200AR My tv only blinking ,cant turn on
adrian_landas the very first thing you want to try is to disconnect ALL inputs and components that are connected to your TV including the cables box etc. Disconnect the AC power cord from the TV minutes. Then connect one local input device like DVD/BR/Game console. Reconnect the power and try to turn it on. Let us know what happens. If it still does not work you need to consider removing the back cover from your TV and take a look at all the boards. Check for obvious damage. Post some GOOD pictures of the boards with your QUESTION so that we can see what you see. Adding images to an existing question There are to many things that could cause that so we will have to narrow this down first. My gut feeling, having dealt with Samsung, is that this is a bad power board, bad backlight array, bad t-con board and bad main board, in this sequence.
