Serious heat issue with Fuze V2
fuzerotr:
I too have a heat issue with my Fuze v2 (bought refurbished from Newegg on 02/06/10.)
Installed Rockbox in Sep. Reinstalled 10/10 or thereabouts, using RockboxUtil (on Ubuntu 10.04LTS.) While exploring some of the plugin apps (clock then lamp) my screen went black. I rebooted into rockbox and the screen came on momentarily. Rebooted into Sansa firmware (v2.03.33), same problem.
Screen would go black whenever wheel light was on. I then:
1. Drained the battery (OF, started music playing by patiently waiting for wheel light to go off, then using the wheel in small increments.)
2. Manually reinstalled OF.
3. Charged via wallplug adapter.
4. Rebooted to OF. Problem persisted.
5. Installed latest Fuze v2 Rockbox as of 10/25 (r28360-101025).
6. Booted into Rockbox. Same problem.
Researched Fuze v2 Rockbox manual, found that wheel light could be turned off. Did so. I can now navigate as usual (I have display turn off after 10 secs). However, Fuze gets hot when charging and when backlight or wheel light stays on. Also, max charge now seems to be around 70%.
I will try charging while rockbox running to see if it still gets hot (while backlight and wheel light are off?)
Just playing music (256kbit mp3) does not cause fuze to get hot, or even warm.
Will post update as I find out more.

Can you compile? Trying out some other values for the second argument to ascodec_write_pmu on line 74 of backlight-fuzev2.c might fix your problem. The last bit must stay 1, but after that increasing number in the first 7 bit should reduce power to the wheel light. 0xF0 for instance should reduce it by a factor of 2 or so. Not sure if thats the problem, and I don't have a V2 fuze so I have no idea if it'll even do anything :)

Charging with Rockbox running, which keeps backlight and wheel light off, does not heat up the fuze v2. Last charge percent reached 93%.
I believe that the "lamp" plugin overloaded the LED drivers and damaged them somehow, so that the screen and/or wheel light draw excessive current (?) and cause the fuze to heatup.
However, I can live with this.
WARNING! Trying the "lamp" plugin may have damaged my Fuze v2

The lamp plugin on the Fuze can't change the LED brightness so that seems unlikely.

Hi,
I have the same issue with my just bought refurbished V2. I set the brightness to 3 and turned the lights round the clickwheel off, but it still heats and the battery drops very fast. With this the Fuze player isn't usable.
Are there any news or fixes for this problem?
EDIT: I now removed rockbox and realized that the player gets also warm when scrolling in the original menu. Is this normal?
What annoyed me most was that the battery drops so fast when scrolling. Needs the battery gauge of a new/refurbished player some time to calibrate?
EDIT2: I just reinstalled rockbox and found out that it heats the player even listening to music with turned off display. And in compared to the OF it's much warmer.. I don't know what's wrong here..
Nico.
