Hi, I got this TV with the power led blinking 6 times. Leds right? But the backlight return seems fine.
Also I use the oscilloscope to check pin 31 but I didnt see any error signal.
Voltages looks fine, but I still have the 6 led blinking even when I tried to solder the 10KOhm on pin31 to gnd....

Re: Samsung UE55MU6120K Boot loop with backlight no video
I just went on try and error, uncover some lines on the flex.
from 12-20 went down to 16-20 if I left any of these lines free the TV goes on reboot frenzy.
but the best I got the TV is this.
Is this the best? Can I do something to get a better picture?

Re: Samsung UE55MU6120K Boot loop with backlight no video
My update for my TV: I did the jumper T-RDY1 and T-RDY3 in #36 and I found that the short was on the left and I isolated the ckv (12-20).
but I got some lines on the screen, how many lines should I uncover?
I cut the jumper after I got image on the TV
I uploaded the video

PANASONIC TX-L42EW6K sinc error
This tv I masked some lines on the right flex to block clk and now it has this problem.
The left side is very slow to refresh.

Re: Samsung UE55MU6120K Boot loop with backlight no video
After reading the whole 7 page of the post, because I have the EXACT same problem, I did the masking and all and I haven't fixed yet.
BUT I did buy a motherboard from Ebay. And had the same reboot loop when both flex where in.
It seems that I have some testing to do on Monday when I get to my shop.Leave a comment:
