Samsung Giga Sound MX-JS8000 not responding

[andariego]

Hi, they have brought to my workshop 2 Samsung Giga Sound MXJS8000 devices, the problem in these devices is that they do not turn on completely, only the "WAIT" message appears on the screen and from there nothing happens, CD does not work, NO audio .
The 2 devices have the same problem. Maybe someone has some information about this, I have tried to look for the service manual but I have not found it. I hope you can help me with this, thank you in advance.

ok, just to add that I already checked the voltages in the power supply and everything is perfect, likewise on the main board everything is fine, I have noticed that this device on the motherboard has an integrated of the RL78G13 family, which while I warm it up a bit with an air gun, the device turns on, it works perfectly and I have all the functions at 100%, after the IC recovers the temperature it stops working.
