820-3476-A MPB A1502 2014 - Display flickering after backlight IC replacement

[Saurabh]

- Got this with the backlight not working issue. No liquid/moisture damage.
- After the backlight IC replacement, the backlight started working.
- Now, most of the time the display flickers after restarts for a few minutes.
- Tested with 2 different ICs, same issue.

What could be wrong?

Did you test with another LCD assembly?

Any fluctuation at BKLT_EN_R and BKLT_SD?
Be sure to have good traces from R7731 to U7700 and D7710.

Clean LCD connector with IPA.
