so today I opened my old Blueray Player(BD-H9500) in order to find some hidden "ports" eg. serial - jtag, and to see what type of stuff it runs on.
It was very easy to open the case, just 3 generic screws, so I removed all those ribbon connectors inside (including that one on the top off course) and I found out that my player essentially consists out of 3 pieces(

• a green smd where the proc sits on(heatsink)
  
  a brown colored pth, which I don't know exactly what it is for
  
  a smd wifi module(seperated)
  
  and a lot of air

so on the pth board I found a strange number(1430) , is it a special pin code to enter a service menu (cause it's not a parental control pin,I tried it) or has anyone a idea what it's for?

Probably a date code for manufacturing tracability: it reads year 2014 week 30
