My older generation smart tv UE40D5520RK has started playing up, looping the startup where it says "Samsung smart TV" then shows HDMI in top left, switches off and does it again continously.
I have done many of the repair options I have found online, like changing power supply cord, taking back off and removing flat cable for 30 seconds.
It did switch back on once, I was then able to update firmware via USB. It worked for 2 weeks but is now back to doing the loop.
No damage to screen or internally, is the TV goosed or can I do something wise, like by new motherboard etc ?
