UE55KS9000 Displaying coloured vertical lines.

[Critical_eVeNT]

My 55KS9000 screen is now just displaying colour vertical lines the full width of the screen.

I have read elsewhere is can be an issue with a loose or damaged cable connected to the main board?

Having has a quick look inside it, all cables connected to the main board seem fine to me with a quick visible inspection.

I have also called Samsung to arange a repair, who have put me on to my local repair agent (They are based 2 hours away so surprisingly I am still waiting on a call back)

Has anyone had this issue and managed to resolve it.

Thanks in advance.

Sounds more like screen defect and not LVD's cables. Screen requires replacement.

Possibly, but there are other areas to check before even consideing that.

I did not think it was an LVD cable but more likely an issue between the power cable and the main board connection.

If not that, then the T-con board.

If it were the screen, I would replace it with another TV. One from a brand with a better service network as this in my 2nd in as many years.

The last one did have a broken/cracked screen and the service offered then was every bit as poor.

Cable between main psu will not generate lines. Tcon is integrated into mainboard as I remember. Do you have photo?

[Critical_eVeNT]

You maybe right, I cannot see a seperate board for Tcon.

All this is trolling though other forums, but no are specific to KS9000.

So could replacing the main board fix this issue?

I would realy like to see lines first before giving advise. but im 99% sure its screen defect

Hello! I got the same problem. The audio and the other tv features works fine (if I use the remote i can have the audio feedback), but the screen shows like a rainbow.

How did you open the back?

Thanks

Hi! I solved the problem. In my case it was one of the flat flex cables that had a burned pin.

Before detaching the cables, I could not see any issue. So try to detach the FFCs

I cut the extremity and scratched the last 3mm of rubber coating

Now the TV works perfectly.

Ciao

I will give it another look just in case, but it looks like mine is the panel that has failed. Thanks for the pictures though this will help.
