Wow, really cool and thank you for sharing! My father recently passed and left behind an interesting stereo I want to keep but it starts in protect mode. Which is a shame because it has a dock for a gen 1 iPod (which he has) and I could dock/listen to his entire music collection. Not sure if his situation is the same, I had taken it apart and seen some videos showing a failed fan can cause this error. The fan is standard 3pin/2wire connector but it's thinner than a PC fan so I'll have to pop by a hardware store and see as it seems fairly common. Regardless, if that's not it, it "could" be an issue with the ICs but before dedicating any amount of time into this (as I'm pretty inundated atm) I just can't see myself ever getting around to it and they're taking up space. I guess this is why they say one mans trash is another mans treasure.
Thanks for this video, good info! I'm a bit late with this but Sony has provided a bottom opening for accessing the main amplifier board's solder side without the need to yank it out. Just undo six screws and off comes the lid 😁
That's some good quality video from 1970,jk. I got a sony receiver with same protect issue. Gonna have to take out the board and check for cold solder joints. Great video by the way.👍
right on,I 'm going in tomorrow to check my amp out. After wasting time trying Sony's B.S. fix, which was unplug it wait 30 minutes and it will magically work. LOL or "make sure the speakers are correct ohms"
Aloha, are you able to tell me how to test if one of those IC chips has gone bad and needs replacement? The problem with my amp is that the front right channel is more than 10 db lower than it should be, even in the headphones. I cant find any loose joints or see any thing wrong.

Sorry. I do not. I'm more of a tube guy. You might try pricing those out. They might be cheap enough to just get one and try it.
Im not a tech guy but may i know what specifically is the problem?
Unit goes into what's called protect mode. Nothing works in that mode. That was because many solder joints were bad and not making contact.
I have a str-de675 with this issue maybe has the same problem
My one keeps going on protecter mode
