Sony Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SONY | HCD-GT3D | The sound turns on and makes very loud clicks and turns off | To solve the problem you must replace the IC PCM1754 which is located under the main board | ||
| SONY | KDL40R485A | Keeps turning on and off then turns off completely red LED flashes 6 times | Tsound are 5 soldering points on the output of the IC9500, the return of the LEDs, the voltage must be the same or otherwise the protection will be turned off. | Changing the bars is correct, but jamping the point that is lowest, the voltage stays the same, so it doesn't turn off, but you can break a limb until you replace the bars. | Beto2828 |
| SONY | KDL40BX425 | Stand, when turned on it turns green then flashes 2x | 24v line rectifier diode shorted | Just replace the diode | Eletronica tensao R, Jacuipe |
| SONY | ADP-160CR AAA | Count have all voltages of 5v when arming the 12v it maintains all voltages | Change ic 41 does not allow 12v to be activated and still maintains 5v from stdby | Replace the same | IgorgamesItabuna |
| SONY | ADP-160CR AAC | All voltages ok, when the power supply is activated the 12v drops quickly | R77 open smd 18b it is 1k5 | Replace the same | IgorgamesItabuna |
| SONY | ADP-160CR AAC | All voltages ok, when the power supply is activated the 12v drops quickly | R77 open smd 18b it is 1k5 | Replace the same | IgorgamesItabuna |
| SONY | KLV-40M400A | Does not turn on standby | Short | Ademar | |
| SONY | ADP-160 TODAS AS VERSÕES | Disarming as soon as it turns on and removes all voltages | Just replace the 12v photo coupler without testing and run for the hug | Deo Eletrônica 8198904-0186 | |
| SONY | KDL42W655A | Turning off, blinks 6 times LED symptom | The LED kit was changed and it continues to turn off and the same LED symptom, normal LED supply voltages. | Aluminum on one or both sides of the LED strip grounding on the TV housing, both have to be isolated from the housing, just isolate them with Kapton tape or whatever you prefer and run for the hug, I hope it helps. | Assistec LG |
| SONY | KDL-40R485A | Vled voltage (35v) varying between 24v and 42v and causing the activation of error 6 protection (backlight-error), but it was not caused by any backlight leds. generated a high frequency noise in the inverter coils. | RT resistor (150k) on pin 34 of IC 9500 altered by air humidity. | Substituir o resistor rt (150k ) do pino 34 do ic9500 | leitemarcellus |
| SONY | KDL-50W805B | Does not turn on, standby flashes 3 times and repeats the cycle | Defect in the hdmi ci, tsound is a short in several capacitors and in different sectors of the pci, after removing the short hdmi ci disappears. | Replace the ci with another and celebrate, correction from the previous post | Luiz Sena Eletrônica HYK |
| SONY | KDK 40R485A | Lower the current of the LEDs, place a resistor, or mount a 12k one between pin 35 and the negative of the IC 9500 chassis | Lower the current of the LEDs, place a resistor, or mount a 12k one between pin 35 and the negative of the IC 9500 chassis | Tsound's even a soldering point, it's the smallest point: Rodrigo Cofferi | Rodrigo cofferi |
| SONY | KDL-55HX755 AZ3G | Flashes 6x LED stby protection | Remove the cable located at pin 3 of the cn6401 "power supply connector" from the connector, bl_error, ground the cable on the side that goes to the main PCI. If the atv turns on, tsound is an open LED on the panel that activates the overcurrent protection. | RUBENS S.OLIVEIRA | |
| SONY | KDL48W655D | Right after switching on, the LEDs turn on, protection is already activated and error 6 keeps flashing | LED drive circuit, after the help of another board I was able to remove the LED drive c.i. and place it in the place of my board. this c.i is the one with several smd terminals on the right side of the board, ok...I forgot to check the position and now that I'm posting the tip I remembered | Replace c. i drive the LEDs, be careful with the soldering station, components fly out if the air is too strong. | MIGUELTV |
| SONY | KDL-40BX455 | Works on 220 but 127 doesn't turn on and the red LED keeps flashing | Remove 680k r9347 from the power supply board, clean the glue and replace the resistor, do the same with the other two resistors in series with it. | Marcelo | |
| SONY | ADP-160CR AAD | Acin-detect giving +or- 1v and power supply does not turn on | Missing 4v on pin 1 of dnp012a | Replacing the resistor r170(5760) of 576 homs with a 151 of 150 homs was beautiful | Deo Eletrônica 8198904-0186 |
| SONY | ADP-200ER AA | The 4.7v voltage of the detect is missing | D21 getting very hot | Just replace the c56 (smd capacitor) of 500nf | Deo Eletrônica 8198904-0186 |
| SONY | ADP-200ER AA | No voltage at the stand-by connector | 1v voltage missing on pin 1 of ic31 | Zd39, zd202, d37 and c46 all leak | Deo Eletrônica 8198904-0186 |
| SONY | KDL-40NX700 | Turns on, appears immediately, has no backlight and turns off. LED flashes 6 times. | Smd ps6800 fuse, at the power supply, on the solder side, in the upper right corner. | Replace fuse, 0.5amp | CARTEN |
| SONY | KDL-22EX425 | TV turns on and blinks 6 times - v-com defect | C.i bd9261efv smd defective on v-com board | Replace and celebrate | Jcabarbosa |
