Third Party > Repairing and Upgrading Rockbox Capable Players

bricked H320 (works as a flashlight now): help please?

hi everyone!

posting the first time here, since i never had problems before. :-)

sometime recently, my H320 (running rockbox r18274) was playing an AAC file (i think) on external power when it somehow crashed. i think i was fast forwarding and/or skipping to the next track or something... no more response from keyboard or remote, even though it kept playing. since it would not shutdown either, i pressed the reset button. it will not start up since.

symptoms:
-> when i plug in the AC adaptor, the screen will flash bright white every second or so. it will not react to _any_ keys, including the reset button. this continues indefinitely (even over night), until i remove external power again.
-> when i unplug the AC adaptor, the screen stays (white) lit at low brightness. it will not react to _any_ keys, including the reset button. this continues until the battery is empty (charging obviously still works)
-> USB is completely dead. the PC will not detect anything, the h320 stays dark (off?) and does not seem to react to any keys either.
-> the harddrive does not activate at all. the drive produces no sound whatsoever.
-> no audio-signal comes out either - not even a "plop" when power is applied.

i am afraid i have a hardware problem, but i just wanted to make sure before i either toss it out and/or attempt to repair it.

any help would be greatly appreciated, since i have not been able to locate a different MP3 player which suits my needs as well. i want my iriver back! :-)
(shame iriver stopped producing/developing this fabulous device!)

thanks in advance,

dominique

If you pressed the reset button and are still experiencing the issue, you definitely have a hardware problem.

Were you using the original power supply when this happened?

piscator:
Dominique,

Grab another H320 off Ebay and don't look back!

Febs,

I was thinking the same thing.  The ongoing 'fried' player experiences resulting from incorrect chargers seems almost epidemic.  Don't know that that's the case here.  I fried one myself after forgetting to reset my variable charger back to 5v -- one of dumbest things I've ever done! Now I use the factory charger -- EXCLUSIVELY!

thanks guys - my thoughts as well. just wanted to verify with the experts! ;-)

as a matter of fact i wasnt using the original charger, because i use(d) my h320 in the car. i set the charger for 4,5V (the next up was 6V) and never changed it since. it worked fine for over a year and a half.

surely, running the h320 at a lower voltage wont destroy it?

piscator:
Damasta,

Let's let an expert confirm this, but my understanding is that lower voltage will indeed destroy you iRiver.

My understanding is that the iRiver charging circuit tries to compensate, when it is not getting enough 'juice.'  If the power source is unable to supply that current, the player fries.  Lower voltage = less available current.

iRiver engineers specified a 5v 2amp charger.  They must have done that for some reason.
