About 2 weeks ago my Hisense 50R6E stopped working, I had some LED strip lights running along the back that were plugged into the USB slot so they would turn on and off with the TV. I fell asleep watching TV and woke up the next morning and my picture was black and the lights were flashing like crazy for 3 seconds then would stop for 2-3 seconds and would repeat. So I unplugged the strip lights and tried to turn my TV on and it didn't work, dark black screen and the red input light just flashed about 3-4 times. I tried power cycling the TV to no avail, I also changed cords and made sure the cord was good, made sure the outlet was good, made sure no breakers flipped. So I then ordered a replacement main board same exact part number and replaced that and still did not work. I then order a new power board same exact part number and it still has not worked. I looked up several video of what I should test with a multimeter to make sure the connection between the main and power is good and everything seems to be testing okay. I have now ordered a tcon board same exact part number hoping that will be it because if I replaced the main, power, tcon what else could it be besides the back lights? Which i also already ruled out because if it was just backlight I would still hear sound and the tv would still turn "on" but I hear no sound and I can't take control of it with my roku remote app on my phone which means it's not turning on and connecting to the registered WI-FI. Please any help or information anyone can provide would be GREATLY APPRECIATED.

I have it torn down so I can see what exactly is going on with the LED lights. But you'll have to forgive me this is my first project like this and I

am most certainly a novice just trying to learn as much as I can. I am worried about these small driver panels at the bottom so I can get to everything, is there anything I need to worry about NOT doing right here? And this metallic looking tape do i need more on hand to put more down when I'm sealing everything back up or? And if I do what is it called so I can get some?

The black goo that I am referring to is stuck ONLY behind each of the lights onto the metal of the TV.[image|3262351][image|3262350]

I am also looking for replacments right now and can only find 2 different kinds. 1 is sold as exactly what I have in the tv with no split in the middle standard 4 pc. Then the other is an 8 pc that looks like it is separated and plugged in again in the middle? Why is that, do you know? And does it really make a difference in quality/ life of product/ or installation difference? The 4 pc is like 60 bucks the 8 pc is 20 thats why I am asking, I have kinda learned you get what you pay for and I don't wanna throw cheap LEDs in there just to have this problem again in a year or 2.
