Samsung UE46EH6030 - Darkened Half Screen, Slow Refresh & T-Con Board Replacement Outcome

Hello, I have a problem with the TV picture. More than half of the screen is dim, it wakes up slowly and at the left end the refresh is very slow, the rest of the screen is fine. I turned on the TV but you can't see anything that was burned out, etc. I tried to do it as in the movie but it did not work.

I replaced the T Con Board with a new one and nothing helped (luckily I can give it back). I have unhooked the T Con tape from one panel but there is also a bit of a darkened screen on the other half. I don't have much possibility to fix it at home, I would have to send it. What could be the reason, is it profitable to repair it?

Hello.
The matrix glass is damaged.
Please enter the matrix model as there is.

You can try to fix it, but you need to have a lot of practice in this type of repair.

I could send for repair, but will the repair price not be too high (e.g. more than 50% of the TV price)? Can you order matrix glass somewhere?
