My Samsung UN60D6420UF (3D model) was first clicking on and off for a few months, but always stayed on. Now what happened, is it clicked, went blank, and then never did come back on. I tried a few things like unplugged for 30 seconds and then plugged back in, turned back on, red light would blink 5 times. Then I held down power button for 30 secs while plugged in, then unplugged, for 15 minutes, then turned back on, and that’s when the loud pop happened on what seemed like the lefthand side. I took a picture of the back of my tv which I can attach as well. Please help! I have all tools, multi meter, solder iron, etc Thank you

@jjen There’s no circle on the image? You would need to check under the heatsinks on the power board for any components that may be damaged. Bit tough on fuses but the other option is to replace both fuses and then before powering on the TV, disconnect everything from the power board (except the power supply to the TV) and then connect the power and check if the fuses hold. if not it’s the power board If they do, then disconnect the power and connect the LED strips only and do the same again. If they blow it’s probably something to do with the LED supply If they hold, disconnect the lEDs and connect the mainboard and check. Basically you’re trying to find out what causes them to blow. Without schematics it is very hard to impossible especially if there’s no obvious component damage.
