Hmm this is weird, after i install CSSU, the TV out is working again

Could anyone test this for me?

Play a music, then close the left speaker with your finger, is there any sound coming from the right speaker at all?

Is the right speaker supposed to be like this??

hello,

my n900 left speaker does suddenly not work anymore, but the 3.5 mm jack works fine. Does your 3.5 mmm jack work (audio left/right)?? Then it is most like the speaker it self.
My n900 is now in repair for 2 weeks!!! by nokia care.
I really miss my n900
Now i'm using my wifes phone, samsung star.......
I hope to get my n900 back soon.

May be the lemon juice now dried up.
Why don't you try un-installing the CSSU and see if it continues to work. It would give some pointers to this problem.
