Philips DVP9000s unconscious

Jaap · 13th March 2006, 07:36 PM

I tried to update the firmware of this player.
The receipt is here:
http://www.avsforum.com/avs-vb/showt...t=philips+9000

But I suppose that this update is only suitable for the European version. Mine was bought in Singapore (no scart). After I tried to power up the machine after updating it switches off immediately.
Does anybody have an idea how to cure this ?

I already have a copy of the service manual and there is a code to correct for the original settings. So I thought I would not have a great risk in trying to update the firmware. But if the machine does not start up at all I cannot do anything. After putting it on the wall socket I see the standby led for a second and then it switches off immediately.

This reminds me of a badly updated motherboard bios.
Usually there is not much hope and every case will be different so you will need someone who knows these players in dept.

Hi,

What steps did you perform to do the firmware update ?

What happens if you hold down OPEN & PLAY or OPEN & STOP when you apply the power and switch it on (these put it into service mode) ?

Cheers,

Jon

Jon,

I tried but it doesnot work because it does not even start with the boot sequence. I suppose I have to bring it to the Philips guys.

Jaap,

I know this is a bit extreme but are you able to desolder the two flash chips and reprogram them externally? I had a look at the flash image and it appears to be an uncompressed 2MB VXWorks OS image + a 100K or so of boot loader. It should be possible to take the firmware image from the zip file and program it directly into the flash thereby restoring your player. There doesn't appear to be any other eeprom/flash device on the board or download header. I'm not sure what else Philips could do apart from swap out the whole pcb.

Regards,

Jon

You learnt the very important lesson that you should flash european versions of hardware with their european firmware-version.

Most people only need one lesson to fully understand the matter

Good luck with the machine, I think it will cost you much effort to bring it back to life.

Thanks for the suggestions.

The machine should have a rs232 connection somewhere, so I suppose the Philips service people can connect a service PC to the player and load the software it needs

True but there would need to be some firmware on the player to enable it to 'listen' to the serial port and download new firmware (just as there needs to be some firmware to read the CD and reprogram the flash). If it's not even switching on I suspect this is a lost hope.

Regards,

Jon
