3 logic boards later...

[dragonmantek]

I have an iMac 27" 2015 that's been causing me so many issues. It will randomly hard-shut while doing any random task, browsing the internet, typing a document, playing games, etc..It was very hard to reproduce as it would happen spontaneously, and had been that way for a while, but it started getting worse and the shutdown became reproducible.

I brought it in for repair and they said that they were going to replace the power supply. That worked for a couple of days but it went right back to the same problem.

Then I brought it in again and they held the machine for over a week. They put in a new logic board, which failed, then put in another logic board to replace that one, which is what I have in this machine now - only to fail again.

So a power supply later, 3 logic boards later, the issue is still at hand. I called up Apple and talked to a supervisor and he told me that I can bring it in and have the logic board replaced for the 4th time..

Isn't this absolutely ridiculous? As I was sitting with the technicians, I told them I knew exactly what was going to happen, and it happened twice, and yet they still want to continue with the same thing. Am I just going to have to constantly go through this?

Really not sure what extra steps can be taken here.

Have you checked CPU / GPU temperatures? Someone just the other day posted that he had to have the fan replaced in a similar situation where they tried replacing the logic board several times too. Maybe heat is frying the boards

Perhaps the ram could cause issues in very specific cases if they are constantly misdiagnosing the logic board at least. May be worth while trying with some cheap secondhand/other ram if you can get ahold of that easily and try that out for a bit before your Apple care gets close to running out.

I've even heard of computer cases being the issue to random shut downs but that was with PCs.

it's not the CPU or GPU temperatures, nor is it the fan or the RAM. all of the above was checked out beforehand. When using the Apple Diagnostics programs, everything checks out completely clear and no issues are shown.

Bringing it in to the Apple Store today for the 4th logic board for this computer. At this point I'm starting to get frustrated, I haven't had a working computer for almost an entire month.

If this is the situation the proposed fixes are nothing more than guesses. My guess, after the second logic board, would be that a replacement iMac would solve the issue.

I wouldn't trust the Apple Diagnostics results. I have a PowerBook G4 which has a problem with its PMU but the ASD testing reveals everything is OK. Use the Apple Diagnostics for whatever problems it may reveal. Otherwise don't rely on the results that everything is OK.

I thought after the 3rd logic board replacement you were entitled to a new equivalent spec iMac? Call AppleCare and tell them this is disrupting your work and you do not want yet another logic board.

they have decided to replace a wireless card, the entire back bezel of the iMac, as the last option. this is absolutely ridiculous. I'm beyond frustrated. I know exactly what's going to happen, I'm going to get it back, and it'll be fine for a day, and then start having problems. At this point, the parts, labor and time has cost so much, not only to me but to them as well. bouncing from apple store to apple store, waiting in line for hours and hours because there are no reservation times available. Then I have to speak with a new technician every time and explain the situation, fresh, every time.

I'm a really cool calm and collected person, but I'm really starting to get annoyed with apple. never had so many problems with them before.
