Turning off after a few seconds. Normal audio | Even changing resistors and capacitors on the STK board it continued to turn off. the cause of the defect was r578 100r | I found r578 100r smd replaced on the side plate. it was 105r, this good resistor should measure 98 or 99r | WTEC |

Sometimes it turns off by itself or doesn't turn on, red LED flashes twice | Remove the glue below and check the change in the values of the resistors r9810, 9811 and 9812 (680k) | Changing the altered resistor or just removing the glue, which in my case did the trick. | mfelipe |

Image "flashing" at a regular interval of approx. 5 seconds | Cause: low quality hdmi cable, tests: 6 hdmi cables were tested, and with only 2 cables the image was normal. on two receiver devices the symptoms were the same with each cable. | The chipsce brand cable code: 018-2222 is one of those that worked, the other was sold without branding or packaging | |

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 |

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 |

This sound arrived at my workshop with the following defect, it does not turn on, the front panel is off, the stand by LED is off | The cause was a short on the power supply and audio output board, I found some components shorted and leaking, they are - pc701, pc702, pc704, pc301 and pc302 - nec2561a with shorts and leaks, q325 and q202 - kta1281-y with leak, d403 - 6v8 changed, r230 and r231 - 390k smd bad, r233 and r232 - 470k smd - changed z201 - sc2001 - with leak replace with original, already on the audio board - q4065 and q4068 - code yw = 2sa2026 - short and leak remove scrap not sold, r4400, r4401, r4407 and r4406 - 100r open smd, r4068 - 2k2 smd with low capacitance, q4004 - kta1023-y shorted, d4001 - 10v smd shorted ic4400 - 4580r smd shorted c4012 - 22uf 63v burst | Defect resolved | Andrei |
