[pali]

I have here D500 with serios problem .. as i wrote above there is no sound and speaker working.
I've changed the Flex cable, Melody ic and HF (usb) connector still not working. When i try other motherboard all is working .. so flex is for sure good and speaker too .
Any other idea why its not working ?
