That is an issue with the backlight cable on the screen. Should be an issue with one or more of the LED return lines for the backlight. Check the repair you did on that cable. This may be useful for you. https://logi.wiki/index.php/A1706/A1708_TConn_Backlight_Pinout_(FlexGate)

in fact it is a problem of bad welding in the lines. It may be due to the type of wire you use to make the bridges.

It has happened to me before.

I have the exact same issue after backligt flex repair on an A1706. Any advice on how this can be prevented?

Okay, I've found the problem. There was a short between LED_RETURN_1 and GND. It was not visible, I guess a tiny little bit of solder ran into the gap between the old and the new flex cable. I have reworked it and the backlight looks perfect now. Many thanks to tcampbell34 for the link.
