Hi guys. I have a Sharp LCD tv with vertical lines. I suspect this is a TCON issue since I get lines through the menu when I press the menu button. Is this correct or could it be a main board or panel?

Hello, 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... -

Hello,
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

Thanks for offering your assistance with this. I'm an electronics enthusiast with moderate level of competence (have a decent lab with two power supplies, microscope, DSO, hot air, good iron, can competently work at a component level on SMDs, design and solder own PCBs etc). I really enjoying fixing things and learning new stuff so took up a free 58" LED TV and have been googling and watching Youtube videos to see if I can fix this! I am happy to go down to individual component replacement/strip replacement etc - it's all in the name of learning.
