Rotel RA-12 Bricked!

[ByteCurious]

Ugh... having similar issues where my Rotel RA-1592 amp is stuck in power blinking light. Trying to update the firmware in hopes it will come back to life and it's not getting recognized via RS-232 cable. Used multiple different brand cables already and ensured settings were correct for the connection. No luck so far. Almost coming to about a week.

thanks for responding.

I did update the firmware on all the cables. First unused whichever one windows installed. That didn’t work so I checked and updated it to the latest firmware from FTDI and ensured that the serial driver and also the com drivers were updated. Theres one of each on the device manager.

Also updated settings on the device manager to the correct communication settings specific for the Rotel Amp which included 115200 baud rate etc.

Unfortunately none of this worked.

Rotel RA-12 Bricked!

I'm really hoping to find help here. I recently purchased a Rotel RA-12 secondhand. It was in great working condition then I decided to update the software. Because why not?... Well, it was more complicated than expected since I have an early model that has a usb connection on the back panel...

Yup. Isn’t that this thread?

I was looking at the instructions but I think it’s very specific to those models. The instructions Rotel sent me do essentially the same thing uses the RS-232 which I’ve tried numerous times with no luck.

I posted a similar thread at DIY Audio but for some reason I haven’t received any response yet. I added some additional information the trouble shooting I’ve done so far.

Would definitely welcome any help I can get. It seems it’s stuck. I think if I can reset it to factory default, that would fix the problem since I believe the issue is caused by the AC Power standby setting I enabled. Kinda sucks that Rotel would release a feature that would essentially brick your amp.

I tried using Putty and Tera Term to send ASCII commands but because it’s not getting any RS232 connection, it isn’t responding to those commands.

There’s a command to reset it to factory default. Also several others including to get its current power status. But nothing comes back as a response from the amp.
