How I board repair for Apple HomePods (covers no-power and blown amp IC)

Описание: MY PATREON IS LIVE! Support the channel here; https://patreon.com/nicsfix?utm_mediu...

NOTE: I previously mentioned the amp IC is also the source of "death farts and restarts", and possibly popping and crackling issues. I've recently discovered this specific issue along with the dc offset pops are coming from failed capacitors around the DAC and sometimes a resistor next to the subwoofer connector. I have a new video up on my channel showing how to repair those issues here:    • Fix your Death Farting HomePod!  

Trying your hand at some homepod repairs? In this video I'll show you how I get it done. Specifically a specific schottky diode and an amplifier IC.

If you want to see how to take your homepod apart without destroying it, check my previous video here first:    • How to Fix a HomePod that Won't Power On; ...  

The 60v5a schottky barrier diode can fail into a shorted state preventing the homepod from powering on once it gets too hot or is subject to too much voltage. The diode failure is sudden onset and your homepod will suddenly no longer power on at all. In the homepod's case, I'm not sure what the exact cause of failure is or what causes it, however, replacing the diode with another one seems to work long-term. Any 60v5a schottky barrier diode will work.

The amplifier IC chip mentioned is what amplifies the subwoofer signal. It's honestly very unlikely this amp IC is the source of any of your problems unless it is obviously damaged. You can replace it with another oem 98-0431 from aliexpress while they are still in stock. I've also found IR4312M to work well so far. There are other IR4XXX chips that appear the same but unconfirmed if they will work! This is not a novice repair, I would suggest getting a couple chips in case you mess up!
