Received today from France this mint Metamorphic Force (Japan version)
I have been told by the owner that sound was missing.This was confirmed once powered the board up, it was mute:
The board uses the ‘infamous’ ‘054986A’ hybrid audio module which in this case showed sign of corrosion due to capacitors leakage:
Insted to try to repair it I decided, in agreement with owner, to use a reproduction of mine wich means a better reliability and lifespan:
I removed the old module and installed some 1.778mm female machined pin headers:
Lastly fitted the reproduction:
Sound was back loud and clear.End of today job.
