@razielsd what model is the TV and is there a pattern to the blinking?


There is not a pattern to the blinking. It is a steady blinking of both the power button and the screen itself. As long as it is plugged in and you hit the power button it just blinks nonstop.

The model # UN60J6200AF

@razielsd this could be a multitude of things. the constant blinking (no pattern) is indicative of an error with the power management system. The quickest way to test is by disconnecting the main board from the power supply board, plug in the power supply board, after that you should see some lights in the screw holes if the power supply is good. If you do not, then you can move on to the mainboard. Worst case scenario would be a bad panel, which can also cause this error. It might help if you post some images of the back of your TV with the cover removed as well as images of the different boards. Of course, a bad capacitor is always a possibility as well. Post some images of your boards with your question. That way we can see what you see. Use this guide for that.

I am going to assume that it could be all of those problems. Would it be cheaper to fix it or just buy another one? Also, do you know a website to buy the parts required?


That would depend on what you find and what boards you would need to replace and availability of those boards. It could easily run you more than a new TV but the only one that can make that decision is you.


i figured i would just replace all the boards and the capacitor if possible? Looking up a few parts it looks at if it will cost a couple of hundred, assuming all i needs is those 3 items
