Macbook A1502 820-3476 No speakers?
Hello All.
Bit of a weird one that's got me stumped. I picked up a Macbook which wasn't seeing the internal SSD, I managed to repair that issue (broken trace) however the macbook speakers dont seem to work.
When you operate the volume up / down buttons the display comes up with a "no entry" sign underneath the speaker for some reason? Sound works OK using bluetooth speakers / headphones, but nothing on the inbuilt ones.
When I look in System preferences / sounds there's nothing listed as audio?
Anyone got any ideas?

C8300 and C8303 and always at pin 1 of both short circuit present;
D7710 short circuit present at pin 2;
R7731 and R7732 and short circuit always present;
C7713,C7714,C7715,C7716,C7717 and short circuit always present;
I also replaced the LVDS connector but the result hasn't changed, even without the connector on the logic pin 1 is shorted..... what...

MacBook pro A1502 - No power Need help
I have a MacBook Pro A1502 with no power.
180-200mA without battery, 1500mA with battery, and orange light on the charger.
Short facts:
*USB with LED lights up.
*No fan spin.
*Adapter sense and sys_onewire is ”only” 2.861V.
I checked the DC board as well and the adapter sense is 2.861 V, I'm not sure if it's too low
That's why I'm asking you guys for help.

Re: Apple MacBook Pro A1502 (820-3476-A)
Your firmware did not dump properly, too many 0xFF. Please do it again, and this time verify the dump with what is on the SPIROM....Last edited by MuertoGB; 11-20-2023, 04:40 PM.

Re: Problem video A1502
hello! It turns on normally, but when the user/password window exits there is no longer any video on the macbook screen, there is sound, I have a backlight because it turns on and you can see the apple. So when I connect the external monitor I have video on both screens and when I disconnect it it disappears

Re: Apple MacBook Pro A1502 (820-3476-A)
No. This is my request for help to the guys. I wrote about it a little higher. If you don't care about a specific SN in your MACBOOK, you will probably find a ready-made file in this thread. There were several of them....
