The HDMI inputs are pass through inputs only. The reciever cannot recieve any sound signals through the HDMI's. The reciever acts as a selector switch for the HDMI inputs only. Whatever input you have selected on the reciever is the one that is being sent through the output to your TV. The "unlock" display shows when there is no sound signal sent to the reciever. There is no code to unlock. This is the reciever's way of telling you that there is no sound being sent to it from that input. Since there is no sound being processed from the HDMI's, you need to hook up an additional audio cable from the device to the reciever (preferrably an optical cable). When the reciever recieves an audio signal, it will then "unlock". I know it is confusing. I had to look into this problem myself, so I'm happy to help. Higher end recievers will actually recieve and process sound signals from the HDMI's. When I bought this one I thought it was going to do the same. That's what I got for trying to save a couple bucks on the cheeper model! Although it is still a good reciever.

STRDG520 : From what I figured out the use of BD for input but no digital optical cable is connected.
I had to use the DVD HDMI connection and the Digital coaxial to get the sound from the Amp. for My HDMI satellite connection.
Hope this helped

Thanks for all the info. It appears that the Receiver requires service as there is no test tone also. However, please clean the speaker cables and speaker jacks and reconnect. Also, try the steps mentioned in the link below.

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.
