Hello Duke, Known good board: (MXIC chip) - Diode mode: .625V - Resistance to ground: 7M ohms Faulty board: (MXIC chip) - Diode mode: .54V - Resistance to ground: 7.3M ohms

I did backup the Bios first before messing with it. Now that I have replaced the chip, I have also upload the image on the new chip. At the time I've started the thread, Bios chip was the original one. Only the U6101 has been replaced with a new one but I assume they are not programmable, am I...

Hello Smiba, Thanks for your precious help. Bad board has a 186ohms resistance to ground whereas the known good board a 300ohms resistance to ground. EDIT: By the way, I have replaced the clock chip with a new one. same behavior. I have removed the bios chip and U6101 which I have both...

Thanks for answering both! Well after digging again on that one, I realized that it may not be a problem near the Bios chip but probably on the PP1V05_S0 line. I guess a possible short could make the the Fan quarter spin right? Since you can see on the pictures that line also had liquid coming...

No Title Hello Duke, Here are some shots. Pretty tough to tell. Shitty camera.

I don't think so. 2012 and 2013 already have difference so do the 2014 I guess. Ebay will tell you... search for a 2012 screen on eBay and see if they report it as compatible for 2014...

Camera is getting power yes. I did already ordered some replacement U3900 chips from eBay with solder balls. I will replace the chip and see what happens. MacBook without a camera... OMG! (customer would think...) Have to try to fix it.

Hello, We have that board which won't detect a camera. We have tried a known good display and same result. I did test in diode mode the camera connector with the camera plugged and not plugged and compared it with a known working board. Here are the results: 0 0 0 0...

Sorry guys but... What if we buy them online, like on Aliexpress?... Please don't me they are programmed?!... I have just removed one

My apologies, I must have tired at the time I did google the writings. I believe I did seach for DSL5220 instead of DSL5520. Thank you Duke!

Hello Duke, Yes it is pulsing. I even have the time to see it showing up on the multimeter. It is so frustrating, you feel so close to have it work. I will post a picture later on. Thanks Duke!

After replacing a RAM chip, all seem to be better. Now since I have removed (stupidely) that U2800 chip, may someone advise what is the brand model of that chip? Thanks in advance,

Hello guys, Well I did some more work and ended up replacing both U7600 and its transistor. Now I can see the fan shaking when the charger is plugged. I did spend hours trying to measure each individual resistors surrounding the Bios + checking the traces/pads but everything seem to connect...

Hello, I have that 820-00165 which won't start however it is getting 2 pulses of the CPU_Vcore and ALL_sys_pwrgd. Liquid damaged near the Bios and U7600. I have reflowed the area and replaced the dirty looking resistors. U7600 was also replaced. I have followed the SPI traces and everything...

Do we have any news regarding how to read/program an SMC? I remember when I was using my old hackintosh back in 2007 (I think) we had that guy Netkas who was a Guru and was able to simulate an SMC. I bet he did some reverse engineering to achieve that. Now, since it has been a long time, no...

try the ASD EFI for sensor issues, not ASD OS

Sad news to start the day... ;-) I need to ask... you are absolutely sure of that or that's just a guess?

Hello, That board was messed up by an Indian shop which I will keep the name secret. The issue is it has graphical glitches when you are not moving the mouse, and that only when using the integrated GPU, Iris. Please check the video I've made : https://youtu.be/OOYrZO6wDvA Board has been...

Ok, let's assume you are right and I screw up the board doing that. Though, in order to understand, what could prevent the CPU rail from being created if U7400 is powered on and CPU_IMVP_VR_ON is at 3.3V. I am also getting less than a volt on both CPUIMVP_TONA and CPUIMVP_TONB which seems fine...

Hello Duke, It seems yes as it still shows up in the system report...
