Power appears on the display protect This defect is caused largely by pre amplifiers and mosfet, I opened the device to check and tested the cable that supplies the pre amplifiers, it has to be 100v or 104v it is ok, I saw that all the if6775m mosfets were good and irs2092s amplifiers, the reason for this device is the right and change all 4 irs2092s and 8 irf6775m I replaced them all with new ones, the sound stopped giving protection, the defect was in these parts they were exhausted due to the time of use, right change them all and the defect will be resolved Device 100% in working order, defect resolved Andre Técnico do posto autorizado SONY
