UN70NU6900FXZ 70” LED TV
One year old TV will not turn on. Several dim flashes on screen, 2 red flashes, then repeatedly reboots.
New powerboard (re: 2 red flashes) did not fix issue.
New main board did not help.
LEDs do light brightly with the left ribbon disconnected from main board or pins 12-20 taped off.
Has sound, but blue screen only with no picture.
This isn’t a solitary issue. Many complaints and repair hacks on-line. What can Samsung do to rectify this issue. No, a 70” TV cannot be taken to local service center. 😠
My 17 month old 75" Q70 did the same -- dim screen, 2 red flashes, reboot, repeat... I had a tech visit scheduled but before the tech came out he called and asked exactly what was going on... he said the 2 red flash means its a bad panel, which would cost me $1200... Take that plus a service charge and that's how much I paid for the TV...
