Put another tcon board in and the same lines. What else is there before I concede it's the panel.Comment

Re: Samsung ue48h6400 horizontal lines
you can try putting some "light pressure" on the tabs along the side in "roughly" the area associated with / near the lines and see if it changes anything. you might get lucky.Last edited by budwich; 01-12-2017, 02:13 PM.Comment

Re: Samsung ue48h6400 horizontal lines
The kids have just been watching a 3d film and from I could tell there was no horizontal lines. Is there hope for the panel after all?Comment

Re: Samsung ue48h6400 horizontal lines
Anyone got any more ideas? I could get another lvds cable just in case it's the cable. Any chance it's an average board fault even tho the lines go over the menus.Comment

Re: Samsung ue48h6400 horizontal lines
Could you try and apply a little pressure on the mainboard while the tv is on and see if the lines go away?I only repair Panasonic plasma tv's! Currently owning a TX-P55VT50 and still searching for a ZT60!

Lines visible on

Coloured blocks random07

FB7
FG6

FR6
Most of them really but some I have to be really close the screen to see them and only then because I know where to looking.
Does this give any useful information? Does it sound like a panel issue and not a cable or board issue?Comment

Re: Samsung ue48h6400 horizontal lines
with this stress test its absolute we have issue with low frequency only .
did you have Line when you play 3D as its 120Hz ?
you can try to log in the service mode. while the TV ON Press the remote -control keys in this sequence
power off - mute - 1-8-2 -power on
1- navigate to SVC read and listed how many operation hour had the display
then at same page of SVC go don to reset all.
after reset all go back again to first page of this mode and go in Option and make factory reset.Comment

Re: Samsung ue48h6400 horizontal lines

Ive had it where a horizontal tab driver caused equally spaced lines on an Led set also alot of other panels in the same way mainly samsung ones dont spend another penny on it OP it will need a new panel or the failed edge driver remove.

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... -
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... -
I posted about this previously but didn't get any response, and I have some troubleshooted a bit so I have more info.
The screen is full of horizontal "gaps" or lines that distort the picture badly, and after about 10 seconds of powering it on the screen starts to fill with red vertical bars that take on the horizontal pattern. After the screen filled with the red bars, they instantly vanished and then slowly started to reappear. I initially thought it was tab bonding failure, but after getting down to them and pressing each one I find zero change in the picture. I went... -

You that have more good than me, do you think it s a panel or can be the main board, because my friend wants buy a new main board....but the tv respond to the remote control, have sound only no picture so i think it s a panel problem that is so broken that i cant fix with tape...or i wrong if someone can help me thanks, i give... -
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...
