Ok, let's try, I don't have schematics, but can try to write it's place:

Put PCB that speaker on left hand and charger connectors on right hand. Now you see processor, flash (under protection), now go right from flash and you will see small black chip 3x4 mm. This is it, he controls lights. (under that black chip are bigger metal collor 2879a). I cant find number of needed chip, because it's too small, and nothing writen.

Hope you will find.

ps I dont have good camera, but its possible to see what chip

You are right.
The problem is solved for me yestarday.

!!! I change this small chip and 2 fuses.
When you desolder the chip you must have +V going there .
I can,t put pic but the fuse is green one near the speaker.
The second fuse that **** for me is near the small chip (green).
Hope i help.
Sorry for my bad english..
