DJM 900 die after firmware update

@Vitaliy > This is highly unusual. Was there a power outage / power spike at any stage throughout the update procedure?

I have no any problem with power. Downloading was processed without issues. At the end displayed message "success"

Maybe it is not s/w problem, but hardware (power supply block)?

Sorry, i'm skip important.

I'm buy this equipment in USA, but currently live in Russia.

So, i'm using 220 V 50Hz

Also F/W was downloaded in Russia

If you're using 220V wall power and the mixer is labeled 110V, you should be using a transformer (if you're not already).  If your mixer requires servicing, I'm sorry to say but it will have to be shipped back to the US as the warranty will not be valid in Russia.

Technical support contacts are at your right.

I found cause of my trouble.

It was power cord!!! :)

Pioneer #1 DJ tool maker!!!

Thank you for your support !

Glad it was something simple!  :)  Thanks for reporting back.

Power cord was purchased independently on local market, i suppose it was Chinees.

So, pioneer has perfect quality!
