Sony Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SONY | KDL-46R485A 1-888-722-12 | Completely off, no standby | Shorted capacitor close to the ic4000, it is the one closest to the edge of the board. With the short, he also blew fuse f4000. As I didn't have this fuse, I replaced it with a ferrite inductor (fb) from scrap metal. | Be very careful because on the first attempt to repair this capacitor I replaced it with a 47μF/25v electrolytic and it didn't work. Only when I replaced it with another one larger than 100μF/25v did the board turn on standby. Furthermore, be careful when choosing the capacitor because the supply voltage is high (19v). The board's architecture is very good, it's every technician's dream since each subcircuit has a fuse, making it much easier to locate the defect. | 2000 |
| SONY | KLV40M400A | When turning on the TV, the LED button lights up green, then turns red and flashes 6 times | Backlight error: short in capacitors parallel to ci 6702 on the power supply board (capacitors c6732 ceramic, c6759 electrolytic, c6753 electrolytic | I replaced them and the RV returned to normal | magaivereletronica |
| SONY | KDL-32R435A | 4 blinks 8817 client | Tsound is a lack of 12 v that powers the screen, tsound may be a short on the 12 v line as well 8817 customer | Replace of ic6007 8817 client | marcos melo cascavel ce |
| SONY | KDL32EX355 | Shaking image | Replacing resistor on the vcon rd14 board | Placed a 1k resistor without success, placed 100r, solved | ANTENISTA |
| SONY | KDL-52EX705 | Turns on and then turns off and indicates error 6 (back light error) | Bad power supply (changed power supply) | 500ma fuse open, it was replaced and it didn't solve it, I checked the LEDs and they were fine, the LED voltage was 180v and it didn't stabilize, I spent a lot of time on this power supply and I didn't resolve this defect, if a friend knows anything related to this defect and just contact us by email, thank you | Alex Lopes This email address is being protected from spambots.

| SONY | KLV-32M400A | Does not turn on, LED flashes 3 times | F4001 e ic4001 | The fuse blew immediately and tsound was no short in any component. changing ic4001 solved it. | André |
| SONY | KDL-46NX700 | No picture, no backlight | F smd jl6020 na psu | ERP-ASSIST | |
| SONY | 32U4000 | It lights up a few times but, when it comes on, it goes out almost immediately, leaving the red LED flashing | The problem is with the lamps. place a diode between pin 17 and ground of the bd9897fs ci, this procedure eliminates the integrated protection and makes it possible to check or, even with lamps with problems, it remains working | Mário Santos | |
| SONY | KV-M1440E | It starts to get dark after a while. it even stops having an image. | Leaky d302 diode | Swap .. equivalent 1n4148 | Marco Marques |
| SONY | KDL-32U2000 | Image appears for a few seconds with sound and then the image fails and the sound is ok | Failure of one of the lamps | Alonso | |
| SONY | KDL-46W4500 | Does not turn on, no voltage reaches the rectifier bridge | Thermal fuse rwt05 6.8ω/142ºc open | Replace for an identical r of 6.8ω and a thermal of 142º in series | C. Santos |
| SONY | KDL-40E400 | Doesn't start. power supply off | Fuse resistance 6r8, 142º na open power supply | Put resistance with a 142º thermal fusile in series | Pablo |
| SONY | KDL-40R450B | Lights up for a moment and goes out, entering protection | Check if tsound are defective LEDs | C. Santos | |
| SONY | KDL-46NX700 | Turns on but no image | F smd jl6020 na psu | C Santos | |
| SONY | KDL-40S2000 | Dark screen, reverse doesn't work | F0002 no open inverter | Replace 3.15a fuse | Edson SP |
| SONY | KLV-20SR3 | LEDs blink non-stop, won't turn on. | Power supply problem, d6102 shorted | ||
| SONY | KDL-S40A11E | LED flashes 5 times, does not turn on | D6903 shorted | ||
| SONY | KDL-S40A11E | LED flashes 5 times, does not turn on | D6903 shorted | ||
| SONY | KDL40R485A | Red LED when you press power the red LED goes off and that's it, | Defect in the power supply, low capacitance, fix the power supply or replace it for another original one | Eletrônica Moura trindade go | |
| SONY | KDL-23B4050 SE2 | Image with little contrast and a lot of brightness | As-04g integrated circuit on t-con | Pascual |
