Ipod nano 2nd gen - white screen

<< < (4/6) > >>

Buschel:
good. can you please do a simple test and comment line 49 in firmware/target/arm/s5l8700/ipodnano2g/power-nano2g.c ? This is something like "pmu_ldo_set_voltage blabla"..

siouxes:
WOW... now works! you're a guru!  :D

i speak to much earlier... when restore from stand by is all white... :-(

OK... the complete behaviour is:

at power on: all works.
go to stand by while hold is off
restore from stand by, for example using the action key: all white.
from all white, is i put hold to on and then to off... all works again...

btw... i am satisfied... for me is acceptable...
tell me if you want to do other tests...

Buschel:
Really? In fact I didn't expect this, just was an idea as this was one of the early changes to the LCD before v3.7 ...
Nevertheless: Good news! :)

Now we need to find out how low you can go with the voltage supply. Reason is that my (and other users nano's) make a disturbing humming noise when the voltage is not lowered. Can you try to experiment a bit a see from what voltage on your controller works?

gbl08ma:
Ha! that Rockbox LCD voltage changes that took place long ago work nicely on most of our devices but not on all the devices... for some reason Apple set the default voltage to the max supported by the displays!

And now? I don't want to have that buzzing sound on the display again! How can this be solved (having all displays working, without buzz sound on most of them).


(Oops: Buschel came first. Here's my post anyways.)

siouxes:
ok... i'll make some usage test and came back to you as soon as possibile... now i have to go home... i am still in office... here is 22.38 (or 10:38 pm)...
