I have been battling this 65'" Hisense Roku TV stuck in a boot loop. Soon as it is plugged in it comes on then flashes the logo every 20 seconds. It is a bit dark on the left side. I had already replaced the main board and the power board. Now I replaced the T-Con board. Through the testing I have done through a process of elimination. It seems that the L2 buffer board may be bad. Can that possibly cause that boot loop? Have replaced everything else other than the network board.
