Replace SAA7011 with SAA7010 in 1st generation player with SoPhi board
Replace SAA7011 ( M4290A ) with SAA7010 ( M4293 ) in 1st generation player with SoPhi board
From the Service manual the correct SAA7011 diagram
Wrong IC number in several service manuals , a SAA7010 instead of a SAA7011. Pin 11 in not an output on SAA7010
From early “Tentative Device Specification M4290A”
See correction SAA7010/11 🙂
Pin 11 DEFM to goes to the “SoPhi” ( sony philips) board
Block Diagram SAA7011 (M4290a)
- Pin 11 – DEFM
- Pin 27 – DADE
The SAA7010 – M4293
Pin 11 on a SAA7010 is now a Input (_CRI) and not an output SAA7011 ( DEFM )
Pin 11
Pin 27 DADE or DEFM controlled by PIN 11
Pin 10 that’s Nice 🙂
Block Diagram SAA7010 (M4293)
- pin 11 in now input _CRI
- Pin 27 DADE/DEFM
How to
Remove the wire between 93-94, close solder jumper pin 27 ( add some solder )
There is a second Solder jumper (orange) and place for extra components (Green) , have to find out if they are needed . I think reset on power up.

Added 1µf and 10k Reset_on_Powerup 🙂
