Got a Dell P2417h monitor that is pulsing white vertical lines. It was working fine then after a bit starting fading black from right to left. Now without any input pulled in it does the pulsing white vertical lines. I have changed the power board with one I got from ebay. Was going to buy a main board but wanted to see if anyone had any ideas. I'm thinking maybe it a bad panel. Thank you for your help.

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 atticus_Hi all,
I dumpster dived a 1440p Dell U2518D screen the other day and figured I'd take a crack at fixing whatever issues it may have. I powered it up to find that even with no signal input the screen flashes rapidly when turned on and has vertical lines across it. I disassembled the monitor and took pictures of the 3 circuit boards inside it along the way.
The three circuit boards are labeled "power board l6256-1m", "LED Driver BD L6257-1". and "Interface Board L6127-1". if anyone has schematics for any of them it would be much appreciated...-

by gpo23Hello,
i order a t-con because i had bad colors on my SONY KDL-40V3000 :
With the new t-con the color are good but there are vertical lines on all the screen :
I've tried the old t-con and it returned to the initial issue (bad colors but no vertical lines)
Is there a way to fix the vertical lines on the new t-con ?
Thank you for your help
