Hi
I bought not working JA555ES as a parts donor for JA555ES and JA333ES. It even didn't power up. Broken shaft of AMS encoder.
Inside I noiticed some flat wires unpluged. Missing loading belt and lever (lock) assy X-4949-790-1 (not available anymore).
But I gave it a try. After pluging all wires it powers up and display shines as new one.
I managed to create lever lock. First I wanted to print it 3D but with no luck so I did it manually and it works.
Next I tried to repair broken encoder. I bought one encoder from Alps and second from Bourns but the old was from Panasonic ;-( . Anyway I put Bourns encoder because it has longer shaft and works smooth and can stand more cycles. The only drawback is that it rotates in different direction than original but does its job. Maybe anyone knows what Pansonic encoder should I get or have spare one.
After assembling it turned out that this MDS-JA555ES has played only for 131 hours and recorded for 64 hours so seems pretty new one.
