I also noted my date to be set back to 2002. I thought it were due to me being forced to take out the battery from time to time when the vibez won't recover at all.

Remove all connections to vibez -usb, charger-
Open the case,
Take out that battery,
Shortwire (shortcircuit) contacting pins to the battery on Vibez itself. Shortwire all three of them, but be cautious to not to breake any of them (they're hard to break btw).

Replace the battery.
Replace the closure case,
Open it up.

(This is my solution to sudden death issues. The problem seemed electrical, so i thought it might be good to free up some voltages might present on the player's circuitry)

just a quick question: What exactly do you mean by shortwire?

In my opinion blackozan means to short circuit the contacts, to unload stored energy (e.g. in capacitors). In most electronic devices capacitors (like goldcap) are used to prevent the loss of data (eg. time and date of clocks) when batteries are removed. Due to the low current these units need those capacitors are able to feed them many hours ( see http://www.panasonic.com/industrial/components/pdf/goldcap…).

@blackozan: Am I right? And please excuse, that I answer the question asked to you.

The most exciting phrase to hear in science, the one that heralds new discoveries, is not "Eureka!" but "That's funny..." (Isaac Asimov)

@MicSan

Thanks for that although, how would one go about doing that? Would you just make contact with the metal pins with something metal (paper clip) maybe?

Also is this safe?!? After about a month or so after formatting my vibez using the windows utility, this problem has again reared its ugly head. I had steadily been replacing music, and thought after it started up again that I had maybe identified the corrupt tracks I had placed on my Vibez. This wasn't the case though, as after I formatted again and replaced all my music sans the bad tracks, it happened all over again.

I'm at a loss; earlier this month was the year anniversary of my purchase, so I figure warranty and all that is out the window. I'm interested in this fix, cause it does seem like maybe its not so much a hard drive thing as a power thing. Who knows? I've noticed that it still does not happen while plugged into a power source. Is this true for anyone else experiencing this problem?

Also, can a hard drive be corrupted and not be fixed by formatting? If so, is it possible to partition the drive of the vibez so as to avoid placing data on the corrupt part of the disk? I'm reaching at straws though. I love my Vibez; it's a great player. But at my place in life, its a pretty good size investment, and I hate seeing it break down like this.

Thanks for listening to me vent guys.

For some reason mine has been solid for the past 2 weeks. Odd?!?!?

shortwire is short circuit, yes.

i'll update my first entry with a picture...

@MicSan: already forgiven.

@occam: your question has both been answered by me and micsan.

sorry for late update...

I tried this but I cannot say whether it worked. The sudden death happened a couple of times after I tried it but maybe I just have to redo it every time the issue reappears? It might be that it happens less often now than before short circuiting the pins but I don't think I can say this with any certainty.

I only recommend short-circuitry only if your vibez refuse to open up again after a "sudden death issue".

Oh I see, so as a faster way instead of taking the battery out and just wait. Most probably I was so hoping for a lasting solution to this issue that I read what I wanted to read

Defector, have the hardware chaps seen this? It strikes me that it's most likely to be completely ineffective and folk-physicsy (if you could really drain the supercap via those pins, the supercap would try and recharge an empty-ish battery, which is clearly the Wrong Thing), but if for some reason the supercap does drain, draining it through a short must surely (for an instant) send more current down those traces than they're designed for?

I don't understand why did you use my entry as a quote for this message of yours.
I said nothing about supercaps. I only said that this method works for most time. And it still does.

And Peter I don't know what degree of Electrics you are, but if you want to free up any charge left on any source-open electrical system you *can* shortcircuit or connect a little shiny resistor between positive and negative pins.

BTW, I also don't know what a supercap is. And from what I've read in this forum I don't think trekstor vibez has any supercaps inside. There are more easier ways to put system on somekind of a steady standby period especially for a system fed with micro amperes and a few volts.

I am really disappointed with Trekstor's performance on Vibez. There are too many defects about the player. It's not just the death issues, sometimes the screen locks up with a full white image. Player continues to play and buttons or wheel is operating correctly.

Is it just me thinking this way: Vibez is producing new problems day by day...

Yeah, people tend to think that us Germans produce high-quality stuff because we have no sense of humour whatsoever. I tend to think though that our humour is better and our cars and DAPs much crappier than the common prejudice suggests

Er, because you're the one advocating this procedure. As there are people who read this board (not me) who are in a position to find out for certain whether the procedure is (a) ineffective, (b) safe and effective, or (c) effective but dangerous, wouldn't we all like to know which of the three it is?
