Connector on logic board looking perfect as well as connector on LCD board also have no visible damage. I tried already with several LCD cables. Also all components around this area are in place and with none visible damage. I will take the diode measurements on the LCD connector but I can...

I have this one with no image or backlight on internal screen. External screen works fine. History is customer tried to replace cracked screen (which had image and backlight but with broken LCD). He somehow replaced the screen with the power applied and now no screens are working. Also not the...

It is probably the Cougar Point PCH that's failing. The known permanent fix would be replace the PCH as reflowing it is temporary (because it is a FCBGA).

It is probably working like the “TekDry” or “ReDux” or equivalent machines. I think the theory behind it is by changing the air pressure it also changes the boiling point and there by it vaporizes at low temperatures and can get absorbed by some surrounding stuff. Maybe it will work if used...

Thanks. You are right. All power rails in TB circuit measured fine and no shorts anywhere. I replaced Cactus Ridge - Same shit. Then I replaced the ports - Same shit. Then I replaced MLB. No more time wasting on this... :mad:

Is there any further investigation on this issue?

This iMac came in with everything working except thunderbolt. It belongs to a professional content creator and the thunderbolt is essential part of the customers workflow as he uses it for external displays and daisy chaining external storage media. The symptoms: Both thunderbolt ports are...

I don’t know. They have slightly different power ratings. So officially they are not interchangeable. I just haven’t had any issues doing it and I’ve had zero customers complaining about the battery life/issues after getting this swap. But who knows. Maybe there can be some rare issues...

I’ve always been using A1494 and A1493 instead of A1618 and A1582 without any issues.

I already beeped me through to the other side of the board via the via and the computer is now working Thanks Duke. Words cannot explain how much i love you :-)

No Title Thanks. The rear camera connector from an iPad Air fits :-) But where does the burned pin go ?

Hi. I don't have a donor board and can't seem to find any online anywhere. But I need the connector for connecting the Touch Bar display to MLB. Anybody know where to find either a donor board or the connector itself ?? Preferably a donor so I could beep my way to where to bridge the burned pins...

Actually Apple got a support site for creating bootable install media. It can be created directly from the MacOS install file since Mavericks by using the “createinstallmedia” command from Terminal. It’s described in Apple support article HT201372 (https://support.apple.com/en-us/HT201372)

Hey Duke can you explain what (rail) got fucked up here? Computer came in with mouse and keyboard freezing 2 seconds after OS loads (but working fine in boot manager) It came form an AASP who had told the customer it was a Logic Board issue. I then put a known good Logic Board into the...

I have seen it when booting from a 10.13 bootable USB install media. I just erase the disk from a Terminal window with the diskutil eraseDisk command. After that it shows up in Disk Utility. Maybe the issue is fixed in the 10.13.1 USB install media but I didn't bother to check it out yet. I...

No Title Screen replacement gone wrong ??

Yes that’s correct. You can always just download the ASD torrents that are floating around on www and use these for models up to 2014. Later models need AST2 so with these models you must settle with the (shitty) build-in diagnostics or use third party “sensor-apps” like HWSensors or iStat Menus...

John: There is difference between getting “certified” and getting “authorized”. Certification does not give you access to AST it only gives you an easier way to work for an authorized service provider (AASP). It is the AASP that is getting access to GSX and AST and you as the certified...

Thanks. Solved. U3210
