Panasonic SA-HT990 stuck in ST MODE
Hi all,
I have a Panasonic SA-HT990 which is stuck in ST MODE after trying to make it region free with an application.
I tried to do a factory reset but the player is not responding. I am thinking that I will have to install new firmware.
Anyone can help please?
Thanks. |

No idea if this helps you, but ...
A few months ago, I managed to put my Panasonic DP-UB424 in "funny" lock mode (no idea if that is the same as your "ST MODE"). Sending the signal with protocol Panasonic, D=176 S=1 F=91 caused a factory reset, and my player was usable again. |

You would need a JP1 remote to do that. _________________ Rob

There are a number of ways to send that command. How did you send the original code-free sequence?
You can use a sufficiently capable programmable remote (JP1, Pronto, Logitech, likely others), you can use a smartphone/table app (Irplus, probably others) you can use some dedicated IR sending hardware (GlobalCache, IrTrans, CommandFusion, IrToy,...) , or you can use a microprocessor board like the Arduino with attached IR LED. Please check out my project. Let us know what you prefer.
For generating, possibly sending, I recommend IrScrutinizer. |

Thanks for the help. I like your project and thinking of building 1 I downloaded the hex file firmware but I cannot download the Xloader program.
Which Arduino Nano version should I buy (3.3V 8MHz) or the (5V 16Mhz).
Thanks, |

I put it here . But I do not want to really condone that program... There is now a downloading script for Windows. You need to have the program avrdude installed (contained in the Arduino IDE, in XLoader, and probably in many other). Just adjust the path to avrdude.exe (at the end of the file) and give the current COM-port as argument. Or compile it with the Arduino IDE.

The Atmega328p version, which probably is what you refer to as the second alternative. "old" or "new" bootloader does not matter. |

Hi once again
I built the 'Arduino Nano as IR sender and receiver'. I tried the code 'protocol Panasonic, D=176 S=1 F=91' but nothing happened.
I tried the original Panasonic remote and captured the signals and what I discovered till now is that the protocol is Panasonic, D=160
Thanks, |
