| SONY | KDL-32BX425 | When the logo appears, the TV turns off and the red LED flashes 3 times | 3v3 regulator u114 I put a 3v3 1117, grounding pin 1. | Davi.sls | |
| SONY | HCD-GTR33 | Does not tune in to the radio | Turn on, press the keys: enter/stop/stand by at the same time | reginaldo moronte, eletronica junior caldas novas | |
| SONY | KLV-40M400A | TV does not turn on, relay activates and disarms then, red STBY LED flashes 4x and repeats. | After setting up the power supply on the bench and all the voltages appeared. but when connecting the main board it killed the 12v voltage. | SMD ceramic capacitor shorted to ground on the 12v line connected to pin 3 of the IC4051. I removed it and the TV started working again. | Jeferson |
| SONY | DSX-A100U | Usb overload | Ic 1304 with problem, remove and jam pins 1 and 6, it is on the right side of the coil and has 6 pins | Rodrigo cofferi | |
| SONY | 40BX425 | TV turns off after being on for a while | Change regulator u701de 3.3 was changed giving more than 4 volts | omar | |
| SONY | KLV-40S300A | Turns on without image, backlight comes on | Shorted capacitor (CD104) on tcon and open tcon fuse | Replace or leave without, replace fuse | Maurilio |
| SONY | KDL-32CX525 | Led pisca 5x | Defective HLR board (little plate is next to the remote sensor board) | Replace or leave without | Maurilio |
| SONY | KDL-32R305B | Turns on and off by itself. | Bad bus connections or open LEDs. | Do the fitting again or replace the LEDs that are showing problems... | |
| SONY | KD-49X7005D | No video | Shorted capacitor on tcon c86 | Replace or leave without. | Maurilio |
