LG Smart TV Randomly Restarting Issue Fixed.

This is a 55LA6230 LG smart tv which had randomly restarting problem. I was able to figure out that this is due to some fault in LED back-light driver circuit or the power supply fault. As the first step I checked capacitors quickly and decided to replace the LED driver IC.
It works...!
Before the video upload, i run the tv for a day continuously to make sure that the issue is fixed.
If you see the issue and difficult to find the LED driver IC, just replace the whole power supply as a quick solution. You can order the power supply from ebay or aliexpress.
