I have two of these units un50tu8000 and un70tu7000 that have displays shorted.The unit cycle on and off with lamps coming on and going off.When i remove the lvds cable to screen i get the intro sound on both and sets remain on with lamps on.Both have identical boards and little over a year old.Anyone have this issue?
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

ESD diode same to any other NU serie... it will located at the end of the right side bufferboards ( when you look from the back side )... you can check if you have U ribbon on the right bufferboards ... disconected and see if you have 3/4 SCREEN DISPLAY
you can also masking the pins on MB side if you can located them which goes to the end of the mentioned bufferboards.

lots of times it can be cleared up with the tape cut-off method, one of many examples on youtube there: https://www.youtube.com/watch?v=E6gkuTP7Lt0&t=900s

Diah yes i disconnected the U ribbion on both sets and no 3/4 picture,looks like shorted caps on left side.I did find a couple of caps shorted.There is tape method but why not remove the caps?Also my models have one large ribbon cable vs others show two ribbons from main board.
