Sony Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| 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 |
| SONY | ADP-200ER AA | When activating the 12v it drops until it reaches zero | Replace without measuring the ic51 (coupler photo | Deo Eletrônica (81)98904-0186 | |
| SONY | DX7 | Sizzling sound on 2 channels | C908 1000-25 placa lateral | Replace c908 | WELLJACKSON |
| SONY | KDL-48W655A | Turns on, lights up green, gives a quick flash of LEDs and the LED stays red with an error of 6 blinks. | In my case I had a LED kit with cable and everything and I tested it, I was able to confirm that it wasn't LEDs, I also had a 40w655 main board and I tested it instead and it worked perfectly, even the power supply to the LEDs crashed, I thought it was strange, but the pwm must correct it as it "sees" the consumption of the LED kit and corrects it. | Changing the main board, I'm not trying to find out what it was...that's for another opportunity. | MIGUELTV |
| SONY | ADP-160ER AAA | Without detect 4.7 | Photo detect coupler with problem | Replace the photocoupler ic43 (even though it measured good in the test) | Deo Eletrônica 8198904-0186 |
| SONY | KDL-40R485A | TV restarts 3 times and turns off with the LED flashing 6 times. | The bd9397efv c.i was arming the protection...I changed the leds and nothing, I cleaned the leds and nothing, I changed the c.i itself and nothing, I changed the 39x50 capacitor and nothing too...so what I did was the following... pin 31 of the ic 9001 is the timer protection, and on this pin tsound is a capacitor, I removed it and put a 10k resistor to disable its protection... and the TV worked without turning it off again, I left the TV in test for 15 and without presenting the defect. | Put a 10k resistor on pin 31 of the ic9001 and remove the capacitor on this pin 31...tv ok | eletronica cachoeira |
| SONY | ADP-160CR AAB | Switching off after 10.5 minutes, sometimes in less time | 12v power supply on ic32 (dda001ag) being cut off | Just replace the ic53 (photo-coupler) obs. even if you do well on the test | Deo Eletrônica 8198904-0186 |
| SONY | KDL-40W655D | No image, remaining normal | Ic6016 burnt | I followed the tip from my colleague junior-poa, all credit to him, it worked really well. | Claudio Eckert |
| SONY | KDL48W655D | Turns on the backlight, the LED is green, but without an image on the display, all voltages are normal, including the dcom. | Clean the display's flat cable on both sides, clean the board with thinner and then reflow the display's dcom board. | Amarildo Callai | |
| SONY | KDL-40W605B | When turning on the Stanby LED TV, it goes from white to green for a few seconds. At that moment the baklight comes on and the image appears for a few seconds as well. The TV turns off and the standby LED flashes 6x constantly, going into protection. TV controls are blocked. Just turn it off by pulling the plug from the socket. | Baklight protection circuit on the LD board/LD HM2 board with a problem. the ld_err line on the cn1000 connector was 1.26v when it should have been 0v. Checking continuity with a multimeter, I discovered that this line reaches an SMD NPN transistor located above the IC2000. Tsound was a shorted ceramic capacitor next to this transistor, preventing it from saturating and changing the voltage from 1.26v to 0v. | Replace the capacitor with a suitable one and the TV started working normally again. We can confuse it with a LED defect, or, worse, condemn the screen. | IZEletrônica |
| SONY | KDL48D485A | Turns on the screen and turns it off | Bad contact out lvds | Fix the lvds cable | Laércio |
| SONY | KDL-32BX325 | No image with blackilite | Remove c301 from vcon board | BINHO | |
| SONY | KLV-40S301A | Does not turn on - LED flashes 8 x | 12v regulator = ic2005 | I put a ci 7812 in its place | Pardal-x |
