macbook air 2015 = stage lights

on an 820-00165-02 board, I've replaced the backlight driver (new chip) and R7716 (was missing) and the display now works. The connector and cable were completely clean of corrosion and no scorch marks.

but on connecting everything up, I am getting visible stage lights.

i don't have a spare screen for this model so was wondering whether there is any other diagnostic I could try to determine whether the fault is in the cable, the logic board or the screen assembly.

found a spare screen and the same thing occurs. traces are fine so it does sound like a bad solder job. I'll reflow and if that doesn't work put a new one on

thanks
