Re: Not you typical vertical line - Samsung UN60JU7100FXZC

budwich, good eyes!

I don't even realize that's what you were pointing to, i kept thinking you were talking about the gold fingers. I will go home tonight and check... it does look like shorted lines in that picture.. i hope it's just an optical illusion

Re: Not you typical vertical line - Samsung UN60JU7100FXZC

Davi.p thanks for your education. Your description would make sense, it's basically a deserializer attached to a current steering d/a for the pixel mosfets. Since the I/V curve is so non-linear for a mosfet, is there something truly called a 10bit panel out there even with some fancy linearization DSP?? Just planning ahead while I search for a TV to buy on black friday... all this HDR10 stuff might be just a waste of money.

So the COF drives the entire column and it has the same number of wires to drive each...

I think I have to agree the failure is at the valley of the fan out chain where it drives only a single column. I learned something new today... didn't know there's a chip on the other side of the film. I did try to clean both sides of the TAB, the COF, and even the area of the rigid PCB near the affected area with alcohol but nothing worked. Pressing the area didn't make a difference either

I still want to learn how this thing actually works though. My understanding is to have a gradient line like mine,...

Thanks for the reply so far. I will go take some better photos with better lighting!

Here's the full story: I moved with this TV (in the box, but it went up/down the stairs without box at times) and then one man mounted this in an awkward above fireplace wall mount. It's all possible I stupidly over flexed the panel... Then I took it to a Samsung "authorized" service center, who just quoted me a panel and said he managed to get the line go away for a bit and then it came back. It's all possible somebody...

Hello All,

This is my first real post so excuse me for any lack of info. I have this 60" 4k LED TV with a blue line on the right side of the screen, this line doesn't go from top to the bottom but instead it fades out as you go about 3/4 of the way from the top... As you go from the top to bottom, it's kind of a gradual gradient until the line is gone or too faint to be visible. This line exist for all input sources and on every menu.

I have some basic electronics knowledge and did some research, so I have checked all the ribbon cables and the TABs. I have attached...
