What Voltages I have in my Ic are:
Pin2 DAC power = 0V
Pin9 VDDIO power output = 500mV
Pin10 VBAT power input = 3.7V
Pin13 Power key input = 3V
Other connections:
Pin17 and 18 = Blue and Green LED
Pin5 and Pin6 audio...

Thank You CapLeaker for reponding.
There is 3.6v-3.7v on the Pin10 feeding the ic but no Bluetooth detect to my phone. Pin17 and 18 are connected to Green and Blue Led through resistors but there is no light at all.
May be a on/off pin is not activated, this is why i'm trying to find any info for the ic....Leave a comment:

What about this BT EHSB14CDB IC?
Hi Guys, first time for me to ask here.
I have a cheap Turn Table with Bluetooth incorporated. The BT ic (EHSB14CDB) has no output, i think the ic is not working but I can't find any info about it.
Do you have any idea about this IC?
Thanks in advance. -
