Boot Loop, Please help, works if ribbon cable is disconnected?
QN70Q6DTAFXZA https://youtu.be/JswMuvDtIR4 - video of it boot looping.
So, the main board and power board and cables are good (replaced them all), screen gets power and lights up full with no issues, however it goes into a boot loop when everything is connected. WHEN I disconnect only the ribbon cable (which is new) the TV boots full, the sound lets me know it is in the operating menu and clicking around dings and selects things properly. Obviously because the ribbon is disconnected the screen (which is on and backlit fine) just has no picture. So the only thing left is this long thin (about 1 in) strip of computer board that runs along the entire bottom of the back that the ribbon cable is plugged into and has connectors that wrap to the front LEDs (I also replaced the metal Y connectors that go to this long stripy board thingy). I cant find this long thin stripy board part anywhere. Please let me know if this is fixable, and how to find this part if that is the answer. Thanks so much, mahalo. - Mike
