This machine runs great except customer complains it runs very hot. so what was noticable - battery reports replace soon as well as running real hot.

i removed board and upon inspecting found that most probe points are...
This little MacBook come in with no power - no charge issue. Upon plugging into my 61w original apple charger it started charging It now charges. When you turn it on it chimes boot logo and even goes into OS. After some time it shuts down unexpectantly. it usually lasts from 5 seconds to about a...
This macbook has backlight issue. When it came in it had no backlight. After sometime display came back - and then started flickering on and off pretty fast for about 10-20 seconds. So i guess whatever the issue was on its way out. Now black screen when i shine a torch can see visual...
i have waterdamage macbook air, everything looks good except no backlight upon closer inspection (near lvds connector) i found the probe point for ppvout_sw_lcdbklt_fb blown.
Does this mean jumper from pin 5 u7701?
this board had a bit of corrosion after some cleanup was running fine. about a month later it unfortunately died, opened to inspect a hole in u9410. Now pp15v_t29 is completely short to ground, i have removed almost every component but short is still there?
would it be safe to...
hey all i got a macbook air and although works fine fan spins up - just after boot.
Fan connector looks good - no damage.
I have tried another fan.
I have tried another io board.
R6060 R6061 R6065 R6010 all measuring good
Q6060 been replaced twice.
what am i missing?
I know these boards have issue with c9560 however even after replacing with a bigger one. I am still getting kernel panic. measures 1.3v Initially when i touch the probe though i can see for like a split second it reads 3.3v?
hey guys. this one came from another store and there has been a previous repair attempt. I only noticed because L7210 was missing I have no other history and suspect no prior liquid damage.
ppdcin_g3h has 20v present but both ppvbat_g3h and ppbus_g3h on F7040 both showing 0.6v. I removed F7040...
Suprisingly very clean board. The one and ONLY problem i have spotted is one of the traces is corroded - deep. DP_T29SNK0_ML_N it connects to pin 2 of C3623.
If you look on the board view all the caps located in the same area are taking 3.3v on the pin 2.
Would it be a problem if i...
Hey all this one came water damage. lvds was bad and ppvout_sw_lcdbklt pins were gone. SO i ran jumpers and turned on the macbook and boom - instant smoke.
So i go over thunderbolt and check all components around u9410 and make sure everything is good. Re done the u9410 now v2 with jumpers to...
This one had no power/no boot. Upon closer inspection i found some corrosion under the grey spongey type sticker next to battery connector. Once i peeled it away i noticed some corrosion and tested components to find short on one of the caps. it was corrosponding to pp_audio_ch and...
Everything works well except the issues mentioned in the title.
I have tested the resistors around fan connector. all seem well. also changed q5660. fan still 100%
