SONY CXD1130 Digital Out

[Htthanh]

Hi guys!
I have a CD player without Digital Out, it had Sony CXD1130 decode chip.

I read several topics in this forum and I learned that I can get Digital out of pin #27 on decode IC, but when I connect "TTL to SPDIF" circuit at pin number 27, I got nothing event "TTL to SPDIF" circuit working just fine with CDROM.
What should I do to get Digital out of my CD player?.

The pin #57 was connected to ground from manufacture. :-(

In addtional: I have ~ 7,4 Khz signal at pin 27 all the time even when CD was stop.

What should I do some one tell me that I should re-load firmware, is it that hard????
