Your TV and company is trash. I threw this  Onn TV in the trash months ago and bought a Samsung from your competitors. I now do as much shopping as I can outside of Wal-Mart and I hope other people who got burned like us, do the same!!!

I got the fix for it..very eazy its the capacitor on the power supply board ..its a 1$ part ...just remove the small back panel and remove the power supply board and unsolder the 10 uf 450v capacitor is located by the two small backlight plugins. 

capacitor 10 uf 450v on amazon 10 pack $8.99 .. here's a little history about me I went to DeVry as a computer technician I was going to replace the board but after doing research my motherboard is an m04 and m06 is plentiful but m04 is rare so I decided to replace the part after exhausting myself on figuring out and tracking and locating what part is bad and what continues to go bad for all these other ones this will fix 95% of everybody's problem out here
