Machine Came in with LCD Backlight blinking.
J5250 and surroundings corroded.
Replaced whatever I could see was damaged.
A small cap on top of J5250 was also damaged.The pad is missing and I cannot see that in the board view to run a jumper wire.
Re-Did that one.
Light is stable now. But LID sensor not working - maybe I ll have to change it.
Another issue is "Battery not charging".
Tried with 45/60/85W adapters.
MagSafe Light seems to work randomly.
Even without battery connected it is showing the battery charging sign.
Connected to PSU and it turned on (with battery connected)
