[C250] Is this a brick?

[krasnayazvezda]

I have a C250v1(rockboxed about two months ago)and it worked quite well until few days ago when I found out that it doesn't work anymore.
When I push the power button, the blue light of directional button goes first, and the light of power button comes after about half a second.
And that's all. Only the lights are on. The screen is completely black and no button responds. Even the power button fails so I have to turn it off by removing the battery.
I tried several things like connecting it to the PC or trying recovery mode(hold+rec+power)and gained nothing.
I cannot remember any reason of hardware failure, and it seems to be working for some degree(at least the power is on, eh?).

Anyone knows what happend to it?

Since you can't boot the original firmware or get into Recovery Mode, it seems the next thing to try is Manufacturing Mode.

You should be able to force the player to power down by holding the Power button for 15 - 30 seconds.
