SET START THEN BACK TO STAND BYE
1.Check eht supply voltage------ok
2.Check driver voltage-----ok.
3.Check +5V--------ok.
4.Check +9V----ok
5.Replace 9V regulator------Problem same.
6.Replace KIA431------same problem.
7.Replace C102 transistor.
8.Then-------

Check 3.3V.
1.Sencer 3.3V/5V.
2.Memory ic voltage
3.Main ic supply 3.3V.
4.cristal voltage.
Then standby released.
Now 5V/9V appear.
