quick search on google came up with this
21. STK5466 (ECG1821)

VCR Positive Voltage Regulator.

Pin 1: VO3 +5.3 V
Pin 2: NC
Pin 3: NC
Pin 4: NC
Pin 5: NC
Pin 6: VI3
Pin 7: VI1 and 2
Pin 8: VI1 and 2
Pin 9: VO2 +12 V
Pin 10: VO1 +12 V
Pin 11: NC
Pin 12: GND
Pin 13: On/off
Pin 14: On/off
Pin 15: Vb (probably around 13-14 V)


this part is a common fault in VCR where VO2 would be missing
 
well the image you posted weren't any good cause i couldnt read it (it is too small and zooming didn't help. could you post the address of the place
 
here is the info i hope it helps im still looking for a better copy of that data sheet so give me a day thnx!


6.10) STK5471 (ECG1822)
12V 1,5A, 12V 1,5A, 5,3V 0,5A. 10 Pin SIPP.



Pin 1: Iout 3 per 5.3 V
Pin 2: Vout 3 control
Pin 3: Iin 3
Pin 4: Iout 2 per 12 V (emettitore)
Pin 5: Ib 2 (base)
Pin 6: Iin 2 (collettore)
Pin 7: Iout 1 per 12 V (emettitore)
Pin 8: Ib 1 (base)
Pin 9: Iin 1 (collettore)
Pin 10: GND

Sembra come se il Pin 1 sia l'uscita di un regolatore integrato per i 5.3 V. Il Pin 3 è il Vin - 20 V tipico. Il Pin 2 è un qualche tipo di controllo on off.

I piedini 4-6 e 7-9 sono l'emettitore, base, e collettore per le due uscite 12 V; si tratta di semplici transistor Darlington collegati in modo da pilotare le uscite in una configurazione emitter follower. Il valore tipico di Vin si aggira sui 30 V.

Informazioni tratte dagli schemi riportati sull'handbook ECG.
