by Stanley1843Hello, I have a screen in where sometimes when I open it pop-up vertical multicolor lines (I would say the most of them are green). If I tun off and turn on the screen the lines dissapear or if I leave open the screen after approximately five minutes the lines gone. I measured the below voltages on the main PCB and on the T-CON board and the voltages are the same when it doesn’t display the vertical lines and when it displays the vertical lines. Also, I cleaned all the connectors very good with IPA. I moved back and forth the connectors and the COF tabs but the vertical lines didn't displayed...

by FalkiHello there, ive recently found an older 55inch Samsung SmartTV.
Sadly it has vertical lines at the left and one line in the middle-right.
I have already tested out the connections and have looked at the soldered ribbons of the LCD panel to see if some contacts got loose by pushing them a bit but with no success.
I have factory resetted the TV as well but also with no luck.
I am afraid that it is indeed a LCD Panel issue but there are NO scratches or any impact-marks..
A similar issue has been posted as well but also with no actual response ...6 Photos -
First. it has no picture at all. i solved it by covering the ckv lines using tape to to block the connections
Second. now has picture but with vertical lines that follow the image. tcon board ic overheating
tried blocking LC lines too, but same results
is it lcd panel issue or tcon board issue?... -
by afexThis is my 2nd broken TV I'm trying to fix and haven't been able to figure out... currently going without any working TVs so am hoping to be able to fix one..
This Samsung PN50B430P2D Plasma has this big block of vertical lines which will fade in shortly after turning the TV on. The lines will sometimes flicker a bit or fade in/out and sometimes it just stays present. The length of time it takes them to appear varies, sometimes its a few minutes and other times it appears immediately after powering on.
I have attached an image of the TV with these bars displaying.... -
by oxi1158Hi all,
My TV had been showing for the last year some faint horizontal lines on all of its right side, about one out of each 4 of 5 rows of pixels. Not much of a bother, they were unnoticeable when watching a movie. Then, all of a sudden the horizontal lines became much stronger and crossed the whole screen, effectively making it a pain to watch.
I watched some youtube video where some guy "fixes" it with some tape on the ribbon cable of the t-con, so I tried that, but to no avail. Actually, after putting the TV back together again things worsened: apart... - Loading...
