Hi, I just joined, and the story of my problem seems similar to a few others I've just read here. I've had my Sony DE575 for about 4 years now with absolutely no problems. However, it's not a constant, but very often lately, while playing from any one of several different sources (CD, DVD, TV) once a certain volume level is reached the unit goes into "protection" mode and shuts itself down.
Due to a change in address I recently had to move & re-connect the unit for the first time, but everything seems to be connected properly & the speakers seem to be in phase. Previously the unit had 2 acoustic research and 2 Bose bookshelf speakers. Now the speakers are 4 Bose bookshelves, with a Optimus center channel speaker. There is no subwoofer. I tried lowering the bass response levels on the EQ, thinking perhaps the it was driving it too hard, but it didnt make a difference.
The volume level at which the unit shuts down seems to vary, but I used to be able to have the volume at basically any level and the unit has never previously had this problem. And there's nothing in the manual at all about the "protect" warning that appears.
Any ideas, advice anybody could give would be great! Please let me know if you need any additional information.
Thanks! Bill Cairns

Re: Unit going into protection mode
You should first have or check the impedance and resistance of the speakers. then if all the speakers and wiring checks good, the only way to tell if this unit is good or the output section has no problems, is to hook up load resistors to where the speakers go, insert 400 to 1000 hz @.775MV into an input, hook up an osilliscope to the load resistors and slowly turn up the volume and see if the waveform clips before it shuts down. I doubt if you will have the equipment to preform these test but a good repair shop will be able to help you out. If it does not clip or go out then its all speaker wiring and/or the speakers.

It is possible the laser or other part of the CD player is faulty.These can stop working for no apparent reason at any time...
I had a Sony system that also refused to read the cleaning disc. I had experienced laser failure twice before on other equipment and hoped it hadn't happened again as the cost would be disproportionate. This also couldn't be accessed for manual cleaning and so I used a compressed airline and blew through every orifice with the drawer open and drawer closed.
I was lucky and the CD player was again able to read a disc again though a few months later it stopped working again for good. The repair cost would have been half as much again as a new system but I had the remarkable stroke of luck to find someone had put an identical model out for the garbage and so I changed the internals and have continued to enjoy my CD for the last few years, though it is again becoming temperamental.
Hi Kevin, This may not be a solution but you`ve most likely burnt out the amplifiers, I have the same model and its just burnt out the amplifiers for the second time. I was`nt cranking the volume and it was running my Bose AM 5`s which are very good speakers.Its expensive to repair and not many tech heads will take on anything "Sony". If you do have any luck fixing it please get in touch. *firstname.lastname@example.org* Regards, Neil.
Unfortunately, Sony isn't going to release parts to the general public for quite some time, a few years at least. Parts for the PS2 weren't even available to vendors until the past 3 years or so. If you want replacement parts, you'll have to wait until the PS4 has been out a few years...
Very sorry, man, my sister's PS3 did this exact same thing. Started out not reading DVDs but would read games, now it won't read anything.
You may prefer telling Sony to kiss your *** and buying an XBox 360 for just $150 more than what Sony wants to fix it. This is a common problem with the PS3s. Microsoft handled their "common problem" by extending their warranty. While Sony... well, Sony wants your money. As does Microsoft, but Sony doesn't seem to care if they get your money in the future, as long as they get it *now*.
Hello new club member. thank you for not willingly joining the "da-gumit my ps3 is flippin broken club" please read on for details.
You have the dreadful blinking red light of death. Long story short the system is broken due to overheating and heat damage to the motherboard and you have a few options:
1. send the system to sony and receive a refurbished system for $150.
2.find a local to do it for much cheaper
3.watch vids on the web (youtube.com) and fix it yourself but it is fairly difficult
4.buy a new ps3.
I hope I have helped and please feel free to ask me any questions and let me know how it goes.
