Samsung UA55D7000 LED TV verticle lines

[LaBull]

Hi, My son sprayed cleaning solution (mixture vinegar and water) onto the tv screen which has dripped down and pooled into the bottom of the tv paneling. The tv was on at the time and when I came in it was a black screen and the power was cycling on every 5 seconds as if it was trying to turn on. I switched off the power once I noticed and took the tv apart. I was able to dry everything as best I could and I let it stand for 24hrs. I put it all back together and the tv works (unbelievable) but 2 solid vertical lines are permanently showing. I've had a look at some other threads but don't see anyone else having these same lines.

Can I get advice on what sort of repair or replacement part would be required?

Thanks a lot.

More likely that the liquid has damaged the bonding of the flexible PCB to the rigid PCB, and as time goes by it probably will get worst due to more corrosion since the LCD was taken apart to get to the tab bonding board itself.

My PCB is connected to the T-Con board which is connected to 2 long flexible circuit boards that run along the entire bottom of the tv. What is the name of these circuit boards? I can't find a description anywhere. Is this where you are referring too? And if so, can I replace the one on the left side as it is below where the lines are showing? It's part number on the circuit board is :- S55240MB3SR4LVO. I can't find a matching description or anybody selling this board.

That green board is the tab bonding board where the LCD glass panel'flexible circuit boards are bonded to the green rigid board.
It is not replaceable.

Ok. Thanks for the information.
So you feel there isn't anything I can do to fix it?

Look at that section of the board where the lines are shown on the screen to see if there is any damages.

Liquid isn't too good for them, I just run a feather duster over my screens every couple days or so.
