SONY MHC-GN900
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
SONY KDL46EX705
Turns on, then turns off and the LED flashes 6 times 6800 smd 0.5 a fuse below the LED connectors on the inside of the board opposite the components Valdir

Red LED flashes 3 times Hdmi ic 2200 short, getting very hot Replace ic2200...works without less hdmi Eletrônica EASI
SONY KDL32B355
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

SONY LCD 50"
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

Device does not come out of standby when pressing power, the disc 1 button LED blinks and the power supply does not go back to standby. Power supply diode in position d906 short shocktty type diode 11eqs10-ta1 on its body written just a1. Joaquim MG
SONY MHC-GTR888 HCD-GTR888
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

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
