You might have burned up some internal parts, it is very important that you keep your unit well ventalated so that it has less of a chance at overheating, check for any internal fuses that might have blown.

Not getting power, but makes a clicking sound when power botton is pressed


One of two things.
1) open power transformer (easy but not cheap)
2) short circuit (output transistors) that opened fuse. (more difficult but less expensive)

The reciver is stuck in demo mode. Can`t get it out of demo mode.


The demonstration will activate the first time you turn on
the power. When the demonstration starts, the following
message appears in the display:

“NOW DEMONSTRATION MODE IF YOU FINISH DEMONSTRATION PLEASE PRESS POWER KEY WHILE THIS MESSAGE APPEARS IN THE DISPLAY THANK YOU”

To cancel the demonstration
Press the Power 1/0 button to turn the receiver off while the above message is being displayed. The next time you turn the receiver on, the demonstration will not appear.


It's in the manual - page 3.

Sony STR DE-445 unit powers up but no sound


Check the fuse, Sony is known for its random problems with sound. The one I have you must tap it on the side. Its a flicker switch inside.

Trying to use a passive subwoofer with STR-DE445


The output of the Sony is "signal only" not power. Being "passive" like your sub. What you need is a sub amp, and they are not cheap, 400-600 on average "min". Unless you have a Velodyne 15 or 18, just get an amplified sub, they start around 150 new. Hope this helps

Speakers pop and rear speakers cut out of surround sound


Hi,
your problem is a bad solder connection of the relay linked to the lautspeaker sockets. I had the same problem and googled for the solution. Since I resoldered the pins everything is fine. That problem is well known and happens to a lot of Sony receivers.

I can send you a link with a detailed how-to-do solution with pictures, however it's written in german language. But you can use some online translators.

Sony STR-DE445 protect displayed


It sounds like a bad solder connection. It just needs to be soldered up, if you take it into a shop just tell them it doesn't need any new parts, it just needs to be soldered up.

Or, if you can solder it yourself, or know someone that can, that would be much easier.
