HCD-GTR66
|
Turn on turn off | I already changed the output, it still had the same defect, turning off, analyzed the board was a leaky 2sc3052 smd lf transistor and changed all the electrolytics 47uf 10v, 4u7 50v, 100uf 10v, 10uf 100v and 2.2uf 50v | Resolved normal league | Andre |
| SONY |
HCD-GTR66
|
Doesn't start | The only LED stays on stand by, I've already tested touch keys, they're all ok, the defect was the 8mhz and 32.768khz crystal with a leak near the computer, I changed the device, it turned on | Resolved | Carlos |
| SONY |
HCD-GTR66
|
I'm sound | This device arrived at my workshop, with the following defect, it turns on the CD, USB and radio works normally, increases the volume to maximum, the audio is very low with hiss, this defect and in the ic400 r2a15216fp short, replace it with the other one and also around this ic change all the electrolytic capacitors without measuring them, they are bad | Resolved audio normalized | Andre |

The remote doesn't work (remote control doesn't work on the TV.) | Shorted remote sensor board. | Sensor board, smd ceramic capacitor shorted, just below the infra. | RNSPTEC |
| SONY |
KDL-40BX405
|
Does not turn on, red LED flashes twice | The problem was on the power supply board, tsound was no 12v and 24v voltage, after checking the board, I found an oxidized rail, the rail that fed the two MOSFETs of the 12v and 24v power supply, I redid the rail and it started working again. | Antonio Zwirtes | |

Does not turn on or turns on and off | Remove the IC 402 regulator. install a 3.3v zener diode with the negative of the diode on the negative of the board and the positive on the pin that receives the 3.3 from the regulator. install a 15r resistor from pin 5 back to the 3.3 volt pin next to the + pin of the zener diode. | Jader |
