MP4 can be recognised but won't turn on (Pics added)

[DarkStarZN]

Heya everyone.

I've got an iPod Nano (First gen) clone, and I had it for about 2 months before it frizzled out. I plugged it into my PC to charge, and the screen never turned on. I smelt smoke, and I immediatly unplugged it.

I can't find the invoice, so I can't claim on warranty.

The MP4 player uses the Firmware 9.1.51, and has the brand name 'Telefunken' on it. It's a 1GB player, and has a 1.5" screen.

It doesn't turn on. I can get it to be recognised as a disk in Windows, and use it and all, but It won't turn on.

In closer invistigation (opening it up), I found that 2 of the resistors have burnt out.


Any help is greatly appreciated. Thanks.

*EDIT*
Pics added, just scroll down.

DarkStarZN , it is difficult to identify the resistor values just from description, as each player is differently designed and these components are located differently on the board.

If I got pictures, would that help?

I'll try and upload some as soon as a can (maybe at the beginning of next month.

Also, thanks to whoever renamed the thread.

Please people? Can't any of you help me?

Well, that's quite a challenge - you might find a solution if you provide even more information: what chipset is used? I can't identify the chips - is it a rockchip or Actions one?
There exist schematics for Actions chipsets and if you're lucky your board is designed following the principal scheme.
You can find 2 pdf's for Actions ATJ 2091 here:
ATJ 2091 pdf (1)
ATJ 2091 pdf (2)
Be warned, your player can use a different chipset and all likely will use a different layout.

But at least this is what I'd try to do: find a principal layout for the chipset used, try to understand the schematics and look for the parts.

Good luck!

That's not a rockchip player...

I bet it is an Actions... If you intend to fix it you can use the excellent pdf posted here... you have nothing to loose as the player is burned... in others words partially dead.

sorry for be so realistic... this goes beyond a software problem

Agree you have nothing to lose but something has caused those resistors to burn out - I doubt if they are all the problem. Sorry to be pessimistic but I thijnk its very unlikely you will fix this even if you can find out correct resistor values. The heat you need to apply may also damage other components.
Good luck but I think this may be beyond sensible repair - maybe best to use it as a memory stick :-(
