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

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.

its horizontal line not vertical one. its T-CON if the LVDS are good.

Re: Samsung ue48h6400 horizontal lines

Well I've got a replacement tcon board in same lines. I've put the lvds cable in switched the panel side into the av board side same lines. It's over the top of menus. Anything else to check?

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?

[Rob0904]

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.

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?

Re: Samsung ue48h6400 horizontal lines

I could give it a go. On a red screen no lines. Just certain shades and colours

1- check the firmware version , there are new upgrade released on 5 Oct.2016

2- download this attached and play them from usb on your tv. and tell which photo will show the horizontal line.

Re: Samsung ue48h6400 horizontal lines

Had a quick go this morning with the images. The ones with all the black white squares, no visible lines.
the green busy images there is only lines visible on the darker green patches.
CVB image there is lines once the black to white is off the black and into the grey colours.
The solids red, green and blue no lines.

Any thought's

each image should at least 1 minute show on the TV..... and write down the file name which had line?

Re: Samsung ue48h6400 horizontal lines

OK, I will do it properly in a bit.

Re: Samsung ue48h6400 horizontal lines

Lines visible on

CBV-32SH01
Coloured blocks random07
FacesCS12
FB7
FG6
FM4
FM7
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?

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.

its horizontal line not vertical one. its T-CON if the LVDS are good.

BS 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.
