SONY MHC-GTR888 HCD-GTR888
Turns on in a few seconds appears on the display protect I opened the device and found 8 electrolytic capacitors bulging on top, I removed them to test, all depleting the value 3300uf 71v, replacing them with 3300uf 75v, and I also tested all the irf6775 and irs2092s, all good, already on the irs2092s on pin 12 - of each one of this circuit to an open resistor, r4605, r4604, r4603 and r4602 - 100=10r smd, but ci 4900 = njm2903v shorted, but regulators kia7805 and kia7905 with leakage change without measuring and very close to these regulators two transistors with leakage q4012 and q4003 = ktc1027-y I replaced all these components, the sound was 100% working, it had auto volume under test, the defect was resolved Andre
