unfortunately I had to give it back before thoroughly testing it - I think the guy will buy a new mobo from Apple. I only managed to run OS ASD a few times only to discover that it crashed at some point (I was not watching so I dont know when exactly) with black screen and fans at high. A big...

Hi guys, I have this mbpr15 here which randomly shuts down and I though Id run some diagnosics first. EFI test was passed with no errors and I am now running the OS part of the test - before the test was available and while it was looking for tests to run, another window was there titled TCON...

tried the ram slots and used known good ram too, to no avail. just fyi.

the "not fixable" is my thing lately... I ll try the RAM slots one by one. cheers duke.

Hi guys, (as a sidenote to the admins, I created this thread again yesterday but although I could see it cause I saved the link or search for it, I could not find it in the timeline) Here is a copy-paste: "As per title this one crashes producing the attached image after maybe an hour of...

Hi guys, As per title this one crashes producing the attached image after maybe an hour of operation. No apparent faults. Any experience with this? (also why search produces no results by motherboard code or motherboard code+fault?) br, George

It was not LD - I didn't confirm that earlier - but I would have mentioned it - and the owner is a student (girl) who says it just stopped working. Using original magsafe. should we look towards EFI or the CPU itself?

Happy New Year to you and everyone. Brain dead means? 1.74V at L7310.

no chime, no mouse light.. I have the motherboard lying on the bench - the mouse should still light up right? IO board & flex connected of course.

Hi ladies and gentlemen - its the macbook air week! Welcome to our show! This one turns on but no image (thus no backlight) - it powers on, green/orange light ok, CPU gets hot. PPHV_S0SW_LCDBKLT is 0V (no shorts to ground in the vicinity) and so is signal EDP_BKLT_EN to Q7707 (this comes from...

OK it was not the SMC but the flex! Got one today and tried it.. It now works ;) thanks duke! u the man.

this looks funky. I replaced U7600 as you said - but I think my oscilloscope tricked me somehow - even with new TPS51916 the oscilloscope reads 0.7V but the multimeter 1.05V (other readings show correctly on the oscilloscope like PPBUS and PP3V42, clocks, etc) - the resistance of L7630 to...

Im using the oscilloscope so I can see the pulse-side and the DC-side thus no room for error :) ..just checked again => 0,68 to 0,7V

USB mouse NOT lighting up, tried other IO board, don't have spare flat cable. L7630 measures 700mV instead of 1.05V?...

8.25 to 8.30V at F7140. (should be 8.6V? -> SMC?)

[SOLVED]820-3437 CPU gets hot (motherboard is powered) but not turning on, NO green light. Hi guys, Another adventure. This one was repaired by someone in the past - that' all I know about its history - also it seems it was LD at that time without serious signs of corrosion. I can measure...

yeah I suspect the MCP too... since I have the tools for an easy MCP swap I will give it a try and if that fails this board goes ..well you know where. thanks a lot dude.

hi duke, this is an old whore so its definitely fucked by others - I checked R5200 and R5201, diode mode 0.490, 3.33 to 3.40V when powered on. I also removed the flex from J3500 to no avail. after 4-5 tries it stopped beeping and R5201/02 (SMBUS_MCP_0_DATA) reads 1,1V momentarily - same time...

had this exact issue, thought it was the GPU but it was C9560 ;)

Hi guys, this one was dead and came back to life after replacing C7771 but it now beeps when you press power button. It keeps beeping once every sec or so... I checked various memory modules on both slots and verified that PP1V5_S3_MEM_A and PP1V5_S3_MEM_B are present at 1.5V (C3110 and C3210)...
