The tv has a great picture. However, the bottom 8-10 inches of the screen has black horizontal lines. Have replaced the ysus and xsus.
Any suggestions ?

Re: PN51N450A2D horizontal lines
I'm afraid that panel is toast. This is an inherent samsung issue with the newer samsung plasma TV panels. Have seen it quite a bit lately.
There is as far as I know no fix for this. Has something to do with the electrodes in the panel coming detached from the ribbons. You can try unplugging and reseating the lower ribbon cables but not sure if it will help here.
I'm sorryDid I leave the soldering iron on? -

Hi guys
I just started fixing 4k TV few months ago. so I am still learning a lot
I got this tv from friend complaint is ghosting or horizontal lines on image.
never saw the original symptom but I took the tv back home. the funny part is that after bringing to home, the tv worked fine no issue for 3 weeks.
then it started to show the ghosting white image.
I started using the tape method, but this tv does not have a T con board and it has only 1 ribbon cable from main board to the tv panel.
it has 3 thin small boards at the bottom of the... -
5.5 year old 85 inch Sony Bravia X950G started showing gray horizontal lines across the bottom of the screen and the picture shifts slightly vertically when it happens. The lines sometimes get bigger/smaller vertically and bounce back. See the video for the problem. It seems to be happening after it warms up after an hour or so. Happens regardless of source. Right now there's nothing but power cable connected and it's happening. We did hook up a new Nintendo Switch to our HDMI switching receiver today, and played for a while with no issues, but this problem didn't occur til a few hours later while...

I just acquired this 3D LED yesterday and it has horizontal lines on a little more than half of the screen. When I first turn it on it has thin black lines going across that makes the image look serrated, and then shortly after patterns of thicker red lines fade in. If I turn it off and right back on it will reset to just the black lines and the red will again fade onto the screen.
I initially thought tab bonds, but flexing the bezel makes no difference, and the fact the image sort of resets after cycling power is different. I haven't opened it up yet to actually test applying... -
Hello,
First of all I'm new here. While looking I found this amazing forum and I'm very happy I did. Now for my problem:
I picked up a Samsung UHD QLED QE50Q67TAU from 2021 for $50 knowing it was defective. The seller said it had black lines and that it could get stuck in boot randomly.
I've tried a new power cable, hard reset, opening up and jiggling all cables, pressing everywhere to see if I get a reaction but I've gotten nothing. I've tried the tape method but I've only managed to get the lines worse.
I'm no expert but I've done the tape... -
Hello!
I have been trying to solve this issue the past 12 months to no avail. I have been a lurker here during that time but finally decided to post my problem and see if anybody knows a solution.
Problem
My tv (OLED55CXPUA) has an issue where it displays horizonal lines of dotted artifacts.
(See Attachment 1)
Self Diagnosing
After a very long troubleshooting period I traced the issue to the T-Con board. If I gently flexed/bend the board I could make the display go from GOOD to BAD and vice versa. I have ruled out the connectors/wires...
