Re: Samsung UE55MU6120K Boot loop with backlight no video



Have you tested the resistors and diodes too?

And I can still recommend disconnecting the Bluetooth module. A defect in it can also cause the error....

But to really rule everything out please tell me which photo is which cable and if it is mainboard side or gate driver side....

Hi fanaticgames,

i had the same error.
Please try to block only the CKV lines without the STVP line. So the pins 12-19 on the left cable(CN1801). You have to work very precisely, preferably with a microscope. Do not block any pins on the right cable. Connect both cables and test if there is a picture.

If there is no picture, you block the CKV lines without STVP on the right cable. So the pins 76-83 on the right cable(CN1802). Don't block anything on the left cable. Reconnect both cables...
