MacBook Pro 13" mid 2012 wavy Backligh issue
the other day i was changing thermal past on cpu and and i forgot to unplug battery and she i was disconnecting lvds cable i probably short the power of lcd something like that -- the screen was white than you turn machine and you could see vertical lines if you look from top angle , so i took it to the shop and the guy fixed this problem , display work now but there is a wavy lines on the bottom of display like if not all leds working , i asked the guy about this and he told me that the problem in display module , so i bought a new display module , but on the new module is absolutely the same thing , not sure where to go from this ,on schematic i see this LP8550 controller i guess. if this would be broken ,i mean could it be part broken like not fully ,maybe you guys have experience in this and could help me
one the pic i show what the guy did to make display work again and what i don't like to see is that just Thin wire,, is this even okay ? or this thing that died there had zero resistance anyway ?
and thats how those waves looks like
Is this a good question?
