I charge mine with a 1000 mA charger and I had no problems, so I think the problem is with the quality of the charger.

Hmmmm. So you say it's not the amperage of 1000 mA that is the problem? Wow. I dunno the brandname of the adapter anymore. But they're selling 'm by the dozens currently at my local MediaMarkt (MM) (electronics shop in Europe). So I'll check the brand next time I'm at the MediaMarkt.

If a faulty adapter really is the cause of me fried Dingoo then I think the MM is liable for breaking me good ol' Dingoo. Things that make you go: "Hmmmm.".

On the adapter itself it says: Input: AC100~240 V, 50/60 Hz. Output: DC 5 V, 1000 mA. So it should not have been a problem. And thank you for your kind replies, by the way.

Thanks a lot for your explanation. To me it also seems that there was a short circuit because my Dingoo kept on producing heat for more than an hour after disconnecting it. To me it seems that the battery discharged very fast, producing a lot of heat. Maybe a resistance burned uot or something.

The charger may be dodgy. But I tried to charge an other USB device with it for a minute, and it seemed okay. However, you might be right about the fluctuations in voltage, but I cant measure that accurately. I tried to measure the Voltage w/ a cheap multimeter I've got laying around. As far as I can tell, the voltage does not fluctuate more than 0.3 V or even less. My multimeter will not measure an amperage above 250 mA (and indeed, the needle almost jumps out of the casing when I try to measure the amps).

Maybe (dunno how!) some moisture/water found its way into my Dingoo. It's the only other explanation I can think of.

Is it possible that a resistance in me Dindoo was worn out causing a short circuit? Or a broken capacitor? Can a device short circuit if a capacitor breaks...

My multimeter will not measure an amperage above 250 mA (and indeed, the needle almost jumps out of the casing when I try to measure the amps).

if you just went and connected the meter across the power supply that's not how to do it and will probably trash any moving coil meter/blow the supplies fuse(if it has one), as ammeters have very very low resistance

Sad to hear that... I think i found the post you mentioned:

Hope you get a replacement somehow by someone.  

Hi everyone, this is my first post but I've been reading these boards since I received my dingoo in late November.

My dingoo also heated up when I first got it(literally within days). Mine is a hk model that I ordered from dingoo digital USA this was around the time before anyone had any idea what an hk model was. I had a lot of things working on it including dingux so didn't want to return it and wait a few week for another one.

Mine specifically overheated at these 2 identical square chips on the front of the board one near the start button and another near the select button.  They overheated one after the other a few weeks apart I don't remember the exact days and when the overheated it it melted some of the plastic from the front of the casing so that it is deformed with 2 small circles near the start and select buttons.  Anyway I figured out these chips were directly related to the speakers when the first time it melted on the right side the sound was just static and the other was fine and after the second they both became static and are no longer of any use. As soon as I figured this out I opened up my dingoo and snipped the wires connecting the speakers to the board so there wouldn't be any current running throug them. The speakers themselves work fine I took them out and tested them using old broken headphones.

Now they no longer overheat and I can only listend through headphones and/or TV out.

I've since overuse and abuse my dingoo and have nearly every hardware problem imaginable; broken shoulder buttons, peeling button letters, etc  but I still use my dingoo every single day. I'm currently waiting on another dingoo, one that isn't an hk model from dingoo digital USA.

Sorry for the long post. There always tons of follow up questions so wanted to get as much out of the way as I can. I hope this helps in some way.

when my dingoo overheated for the first time it was plugged into the charger and playing music on full volume. i unplugged my dingoo but continued to play music on full volume and it was still overheating. the battery got so low because of the overheating that i tried to charge it in again with everyting off but it was still overheating. unplugged my dingoo, turned it off completely, and left by the window to cool off. about an hour later i after it cooled down i tried to charge it again, this time the battery was completely drained and wouldn't charge and wouldn't turn on at all. i disconnected and left it to cool down overnight. the next day i charged it through the computer's usb charger and it charged fine without overheating. it never fully charged through the computer at least the charge indicator never completely filled up this way. eventually i went back to charging it through the wall charger and it charged fine but still not fully charging but not overheating. at some point it was able to fully charge again but i have no idea why. it overheated 2 more times after this that is when i figured to cut the speaker wires and turn the speakers off.

now my dingoo sometimes decides it won't fully charge and sometime it does i have no idea why and i charge the same way all the time, through the wall charger while i sleep.

i hope this helps you get your dingoo back up and running.

It is said that Deal Extreme starts selling Dingoo's again in March 2010.

i have been fighting with deal extreme for over 2 months to get my money back for a dingoo i've already shipped back to them. i've heard nothing about them getting it back in stock. in fact i was told they would no longer be selling the dingoo.

i ordered two from them. one was black and one was white. both had issues. it took 2 months to get a new black dingoo sent out and i'm still waiting (after 3 months) to get a refund on the white dingoo. my best advice is to avoid deal extreme at all cost. their customer service is very low and if you have a problem with the dingoo you will regret purchasing from them.

as for charging i use the charger that came with my creative nomad zen micro. you can pick up the real charger on ebay for next to nothing. this mp3 player is no longer made so make sure you are getting the real thing and not a 3rd party knock off.

facts about the real plug:
its white in color
it says "Creative" on the front
model number: scp0501000p
input: 100-240VAC~50-60Hz.0.3A
output: 1000mA
part number: ad20000002870

good luck!

Your mainboard is probably wracked because you shortcircuited the usb ports. Open your dingoo and look for the speaker cables. Mine got a loose one and it could couse a shortcircuit, too.

Meneer Jansen, don't count on the MediaMarkt being helpful at first in reimbursing any costs. They won't help you.
First threaten with wanting to speak to the manager. If that doesn't work, threaten contacting the main office. If THAT doesn't work, threaten with contacting the Consumentenbond.

It's sad, but that's probably what you need to do to get them to reimburse you for broken adaptor + damage it caused.

Thank you very much for the advice. i don't think they'll agree with me that they are responsible. But I think I'll give it a try. First I want to gain some more electrotechnical knowledge so I can prove it was that bloody charger. I've still got  week to return the MP3 player.

@Santino: I was lucky. I bought a pci card with extra usb ports. Now I do not have to buy a new mainboard (i.e. a new PC).
