sx-1250 lights

[Robayb]

All the orange selection lights have gone out at once . The speakers A,B,C and the inputs ( fm, phone, etc) are all off. Is there a fuse that may have affected these or are they wired in series so if 1 goes out they all go out?? , it's hard to believe they are all burnt out at once. thanks

The Fuse Fu4 1A on board AWR-107 which supplies 23 volts outputed on pin 8 to the AWR 106 stabilizer board pin 7 which is regulated by Q12 and Q13 to provide 5.4 volts on pin 8 which goes to the lights

A rebuilt stabilizer board will do wonders, or just replace the trannies that goat mentioned
