Help,

Bought a Playon!HD in december 2010 in the Netherlands.
Have been upgrading Firmware up to Firmware_PV73100_v7.4.4.r7317_European (early this year)
Further info (at least, that it was before problems started):
Bootloader: 0000.0202.1026L
Board: 1073DD C+
YAMJ 2.6 snapshot r2730
YAMJ GuiConfig 2.0.0.
My computer: Windows 7, 64 bits

A few days ago the Playon!HD started to reset spontaneous after a shutdown. Only way to shut it down, was by switching off the main power.

I searched for a solution on this forum, and found this topic:
[HOW-TO] Prevent the PlayON!HD from automatically rebooting!

First tried solution 1. (repair HDD). - The Playon kept on rebooting after fixing the disk..
Then tried solution 2. (disable autoscan storage) - It kept on rebooting.
I followed each step exactly as was prescribed in the text, but to no avail.

Wondered if there might be something wrong with the firmware, although I did not touch it and everything worked fine up until now
(have had some problems with YAMJ some time ago, but that was solved with the help of Andy - changing square brackets in filenames into rounded brackets, like "filename [cd1]" into "filename (cd1)").

So I decided to do a rollback according to the "ACR-PV73100 Firmware Recovery Guide". Have done this before last year, after encountering reboots, and then this helped.

But not now.

I used a FAT-32 stick. No problems with flashing in the first step. It completed without problems. But step 2 failed.
When I started the Playon and wanted to go to the SETUP menu to start step 2, the system shutted down completely. With completely I mean: the front button went from blue to off, and not to red.
I tried several times, but always, after about half a minute, it completely shuts down.
It didn't matter if the disk was in the Playon or not. It didn't matter what I did in the menu. I could change the language if I was fast enough, or set an ip address, but always, after a short period, it switched completely off and settings were lost.
Flashing anew with a new download of firmware v7.0.6.r4318 did not help either.

What to do???

Have you another power supply that you can try? Sounds power related.

Thnx GregiBoy for your reaction.

I do have another one, 12V, 2A for an USB (SATA) disk cradle, but with the wrong plug. Too thick.
But I have a regulated and variable food supply that I can try on it when I can find the right plug.

However, I do not think that is the problem. Because I noticed the Playon is switching completely off (switchlight switches off and TV screen turns black), but disk keeps on running.

P.S.: The Playon stays on for about 40 seconds every time.

It happened to my PlayOn!HD, now it's just a piece of junk..

@ soojo and voltaren

If you both have installed internal HDD please disconnect it first and try to use and play from an external drive and monitor again. If still shows you the same problem then sorry to say that you already have a defective player.
