This photo also shows that this pin is a dummy, there is no conductor. (copper conductor inside yellow)

I thunk you are right. Since none of the cables (lvds, u ribbon) seems to be damaged, I have taken the risk and bought the pcb board off ebay. I will update this post as soon as I get it changed and hopefully fixed. Thanks to all for involving and helping.

Is it really? I am no professional so I might be wrong. Can you confirm looking at this picture please? Thanks

this is wrong theory... never being 2 U ribbon defect at same area.... your eyes are tired.. i wrote don't trust your glasses.. only magnifier or telescope can see if there are wrong with pins.
or you bought this TV as it is now !!!..
from the photos you posted before we can see the U ribbon cable both side look like larger than original they didn't sitting normally flat.. but there curve and this should never happened with U ribbon. .. they should Flat connected between the tow parts if panel side buffer boards.

I have no idea how these ribbon cable should be inside the tv, you definitely have more experience than I do. If I bought the tv as it is, that's for sure, I haven't touched it before developing this issue. Then I believe it might have been fixed before as when I bought it , it wasn't brand new. I will look for a magnifier and go over them again.

It should, but at least one of the u ribbon should be good, while both of mine have that highlighted pin not connected to each other. We can see from the picture that the highlighted area shows a thicker connection between the pins, which I think it's meant to lead power between them. What i think is that The lvds delivers the power to the lower board and from there, the u ribbons are supposed to take it to the display. Does that make any sense? I can't find a better explanation.

Update: The lvds is perfectly fine, I have tested it with the beep test (continuity) every pin.
What I have found out is that on both of the ribbon stripes CSF01, the pin highlighted in the picture did not pass the beep test, on both of them there is no continuity. Could this be it? Please see the photo.

Is this the right way to do it? Please check the picture
I know that if the caps beeps when I use the multimeter, in most occasions its a bad capacitor.
I also know that if I set the multimeter to 20k to check the ohms and the value is not going from 0 to higher, that's also a bad cap.
Correct / guide me if I am wrong please. Thanks

in case the LVDS all PIns are fine same long.. no one short than others.... then put it back carfully..... put the TV in stand by by remote.... after TV in standby mode push with remot this pne afte other
INFO --- MENU-- MUTE--- POWER ( this is service menu = in case it show to you service menu.... dont do any things just plug it out from wall socket... same case if the screen show blue..... just plug it out from walll and try again..
its possible because the first time you put U ribbon not correct.... the MB change mode... hope this will help.

Thanks dude ! I will definitely try this now. By the way , if I cast YouTube from phone to tv, the music starts so I think this source should have worked , right?

Re: Samsung 65" UE65TU7000KXXU VER:02/UTU7000 TV Blue screen

yes the white one are LVDS take it out from both side and inspect all pins carfully

[gbbradshaw]

Re: Samsung 65" UE65TU7000KXXU VER:02/UTU7000 TV Blue screen

in this case... take out the LVDS and with yours mobile camera or magnifier inspect all pins.. you have one or more from one side or both cut out short ..

LVDS, the white long cable coming from the PCB to the CSF01 ribbon cable, yes? Where should I look? Along the length of it?

Re: Samsung 65" UE65TU7000KXXU VER:02/UTU7000 TV Blue screen

dont play with lvds..... just remove one u ribbon from each side complete and turn on see u will have picture 3/4 screen or blue 3/4 screen

what do you mean no result ????? tv didnt boot or you have 3/4 screen blue or all black explain No result

Sorry, blue screen 4/4 . If I press the channel button on the remote I can see the blue screen going darker and light again, as if changing the channels normally, if that makes any sense

Re: Samsung 65" UE65TU7000KXXU VER:02/UTU7000 TV Blue screen

Turned off the tv. Lvds plugged in. Removed the left U ribbon cable, nothing changed, turned the tv on, no change.
I did the same with the right side of the first U ribbon cable, same result.
Again, I did the same with the right side U ribbon cabble, following the same steps, no results.

You can try taping pins on lvds cable going to panel to see if you get any sort of picture.

It's a trial and error kinda of thing. So might have to try several times covering different pins

Hi pal. Thanks for replying.
I have tried that using a cotton bud and gently going over every bit of lvds/ribbon cable existed, going from left to right and so on.
