No picture after removing back panel UN85TU8000FXZA
Hi I have this TV that was damaged and had a hole in the rear cover to the right of the power supply. it had a vertical line but started normally, loaded up and displayed normally. I laid it on its back cover on cushions and detached the cover with a plastic slide. When I stood it up normally to remove the cover I had a little difficulty with the bottom removal and realized after taking it off the motherboard was attached to the cover and the plastic piece of the cover attached to it stayed on when the cover came off. I found the broken pieces of the cover from the on the bottom and also one had lodged between the ribbon wire from the mother board to the IR controls and ribbon type connections. Once I removed all the broken pieces I ensured all connections were properly attached, wires, motherboard, power supply and lower boards looked normal I plugged it in and the power came on for a few seconds ( the vertical line was gone), dimmed for a few more then turned off and then repeated this over and over. Initially I thought I had caused trauma to the lower on off button as I did not have padding under this when I was removing the cover so I placed padding under the unit to raise that up and it did the same thing. If I disconnect the power supply the unit illuminates and when I plug in the motherboard it shuts off. If you can help with this problem it would be greatly appreciated! Thank you!
@labadida Post some good pictures with your QIESTION of what this all looks like i.e. the "damaged" area and your boards etc. Interested in the hole of the back cover as well. Right now, from what you are describing, it sounds like a bad main board. You disconnect the main board and trun the TV on the backlight comes on and stays on. That means power board is ok. Reconnect main board to power board and turn it on, if backlight comes on it's the T-con board that will need to be repalced. Right now, prime suspect is the main board. 在已经存在的问题里加入图片

Hi oldturkey03, thanks for the info on the main board! I ordered one and look forward to placing that next Monday when it arrives! I don’t know how to post photos on here but will keep working on that! I will also post on how this goes so thank you so much!

Good morning @oldturkey03 , I have taken a video of what the screen looked like prior to me removing the back panel, the power supply the motherboard and a short clip of what happens now when I add power to the unit. The last video action continues to repeat itself over and over if I do not unplug the unit. I Cannot control the television by pressing the off button or using the remote the only way to stop the repeating process is to unplug it. Thank you for so much for looking and any advice would be truly appreciated. To note I did purchase a power supply and motherboard and the power supply (came from a functioning tv per seller) but it does exactly the same thing. Thank you
