Sharp LC-70LE757U right side more dim

[Bmwducati]

I have the LC-70LE757U, had horizontal rolling and flickering, after research and time, decided the driver tabs were the issue on the right side (looking at front). I removed all right side tabs (all 5) - removed the two right side tab boards and lower ribbon cable that was attached to the right and bottom driver tab boards. No more flickering or lines.

ISSUE: The right side of the screen is "darker" than the left, with the furthest right 1/8 or so of the screen being even "darker" yet.

The driver tab contact points on the LCD appear to be very clean. I have tried replacing the power board and the TCon board with no improvement.

Please advise. Thanks in advance.

i kinda notice one side being slightly darker after removal of the tabs but not your extent. i think your supposed to keep the side board connected.

All the guides I've seen/read do not leave the board connected.

Really hoping someone may know where the issue is originating and/or how to fix it.

Still looking for a solution to this problem.

The TCON and SMPS boards are not the source of the issues.

If you still have this TV, can you post clear pictures of the back with an overall view of how the boards are connected and clear pictures of all the bond tabs that are remaining on the TV (left, right, bottom).

Do any of them show signs of corrosion? Did this problem start by itself or after cleaning the screen? Windex damage is common in what i've seen.
