Hi
Recently I got MDS-JA555ES. Previous owner didn't care much about it so it visible on the front panel but also didn't use it. Total play time is about 220 hours and only 3 hours for recording.
Today I noticed strange thing. Power is on, display is working, seems it is playing but every button is inactive. I can't even switch it off or eject minidisc. I had to remove plug from mains.
I checked all easily accesible connections.
Could it be temperature and humidity problem? It is so hot.
