SONY Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SONY | HCD-GTR6H | I'm sound | Glue it under resistors 1327 and 1343, lowering their value, dropping the voltage to 9.2v. | Ronaldo Vieira | |
| SONY | KDL-46R485A | After some time on, the backlight turns off and flashes until it no longer lights up. Even with the backlight turned off, the standby LED remains green and does not blink 6x. also the sound remains normal. | After making the jumpers across the entire bus and checking that the LEDs were good, I thought it could only be a defect in the inverter circuit, but it was also fine. the defect was in the bl-on that comes from the computer to enable the inverter. | With the blower at 370 degrees on top of the computer for 5 minutes. In my case it was resolved. | Wagner Gois |
| SONY | KD-43X705F | Does not turn on, red LED flashes 4x | Power supply board generated 12v and then disappeared | Shorted capacitor removed from the 12v line of the tcom board | LEO DA MEGA SYSTEM |
| SONY | KDL46EX725 | LED blinking and won't turn on | Remote control sensor shorted, just change it. | ||
| SONY VAIO | VGN-FZ21M | Intermittent video, sometimes with artifacts. | Gpu reflow. Raise heatsink "pins" to improve contact with the GPU. | ||
| SONY | KLV-40SL50 | Turns on green LED has power supply voltages and does not turn on blacklight | Reflow or reebaling in the processor below the main heatsink | HP ELETRONICA | |
| SONY | ÉX88 | Doesn't start | Stopped | Paulo | |
| 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 |
