Displaying vertical lines, dead t-con?

Hello everyone. I need help with my suddenly broken Philips 51PUSsomething… the problem is vertical colorful lines thought whole display. What I did is open up the tv and check the t-con board, which has one connection to the motherboard and two to each half of the LCD matrix. I plugged out each ribbon cable to see if something changes, what I got is one half white and second showing same lines as before, same in reverse. From what I have read in this situation the problem is not shorted LCD matrix but t-con board, am I right? Broken motherboard is also unlikely because sound and remote is working. I will be grateful for every tip. Kind regards, Alek

So basically that’s how it looks like after replacing the recon board and the main board, unfortunately without any result. The white lines on the photo is the Philips logo it’s trying to show. So I guess the problem is the display and all that mess is going to trash?
