Power issue or led backlight?


Novice Member
Hello all,
I have a hisense, model 75R6E1 75 inch and I'm facing a little problem. A few days ago NY wife was watching TV and the screen went black. She could hear sound and all that. Well, I unplugged it for an hour and tried to do a hard and soft reset and nothing worked. I tried all suggestions on other forums but nothing. I noticed when I plugged it back in the title flashed bright like normal for a brief second and went dark. Then the power light blinked 16 or 17 times. Could this be a problem with the leds themselves, the driver for leds, power board, or main board? I replaced the t-con board already since it was the cheapest and that was a suggestion from another person. I would really appreciate it help before I start buying parts.
