Hello,
I have had my z906 for two and a half years now.
For the past month, the sound cuts out, the console freezes and bugs.
No matter the volume of the console or the PC, no matter the volume of the sub.
There is also no specific timing; these issues happen unexpectedly.
This must be due to an electronic hardware problem,
but what could it be?... A dead capacitor or something else...
Has this happened to any of you before?
Or, if you know about electronics, could you guide me?
Thank you
Configuration: Windows / Chrome 60.0.3112.90

I solved my problem on my own...

If it doesn't display due to ads, here is the cause:
Many devices of this type break down after about 2 years and according to my research, almost all for the same problem.
Symptoms: the control panel of the console freezes and the sound cuts out.
The culprit comes from the 5V from the power supply board, which is ensured by an LM1116 type IC; the voltage is not stable and drops to 3V after 5 minutes of operation.
The culprits are the 2 capacitors of 47uF (which are not bulging) located at the input and output of the 5V regulator. These caps are defective due to the 2 power resistors of 5V and 12V nearby, which become extremely hot. The 5V regulator also becomes excessively hot because the manufacturer did not choose to mount it against the external aluminum face. (Personally, I made a modification to cool this regulator.) It is also necessary to redo the soldering on the 2 large resistors. (see photos)
Note that all components are glued with a very strong black adhesive, making troubleshooting on the amplification/management board nearly impossible.
