Sony Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SONY | KDL-32R305B | Don't turn on, flashes the LED 6 times | It is necessary to inhibit backlight protection | Place a 1K resistor (Backlight CI pin 31 - BD9397EFV) for the earth. Friend Dennys Gross Tip I only replaced the value of the resistor | beto2828 |
| SONY | KDL-40EX525 | Does not drive, LED flashes 6 times | In the TECHNICAL MANUAL blink 6x refers to the backlight and/or food of the same | Following colleagues, disconnected the power supply of the main board and activated the same externally to see if backligt it worked. It worked perfectly and even stabilized 12V line. I turned the main plate and defect returned, I started searching 12V line in the main and I found early and short protection. Next to the smaller power supply connector has an escape SMD capacitor. Replaces and the TV has been working again normally. | Olibio Pereira Estudier |
| SONY | MHC-GTX787 | Display does not light up | Transistor Q-1291=2SD1859TV2Q | Tsound is no negative voltage on the display, just replace it and run for the hug | Andy Poison |
| SONY | KDL 22BX325 | Sometimes it works, other times it doesn't | U701, 3v3 regulator with problem | Cece eletrônica Brumadinho MG | |
| SONY | KDL-55HX755 | Press to turn it on, it activates the green LED and then the red LED flashes 5 times indicating an error on the T-con Board | The ear of the LVDS cable on the side of the main board is broken, missing or bent and this means that the cable does not enter the connector correctly, giving poor contact or shorting and then the TV activates protection. | Replacing the LVDS cable | Eletronica SV - Guaira PR |
| SONY | KDL-60W855B | Turns off in seconds with error 4 | Sony KDL-W855B turning off error 4 Isolate LD_ERR wire that arrives at the power supply and ground the corresponding pin on the power supply | Ângelo MG | |
| SONY BRAVIA | KLV-40S510A | inoperative, does not turn on or come on standby | I replaced the ci that regulates 5v (mip2h2), I replaced the photocoupler and the capacitors still didn't work, the defect was a 6.8v resistance below the relays | the 6.8 resistance was replaced in the (r6016) position, problem solved!!! | eletronica dj |
| SONY | KDL 40R485A | turns on backlight without the logo and turns off - standby led flashes 5 times | v-com board cd06 - cd07 - cd08 - cd09 one of them is shorted | eletronica millenium | |
| SONY | 90K GH-072-42 | PS2 DOESN'T TURN ON | SHORT IN THE 7.5V VOLTAGE LINE OF THE REG 7805 | ISOLAR O CAPACITOR CERAMICO External Link... | @JOHN GAMES |
| SONY | KLV 37L400 | Strange picture | replace for 15g at t-com | replace for 15g at t-com | Rodrigo cofferi |
| SONY | KD-55X705E | doesn't start | power supply board | none other or repairing the power supply | Wellyngton anjos fidelis |
| SONY | XBR-52LX905 | It arrived with thick vertical red stripes in front of the picture and artifacts on the menu screen, then it stopped turning on and it kept blinking red stby 5x | The defect with the red stripes was the t-com, but even with a new card it started flashing stby 5x intermittently, so I cleaned all the tcom flats and it worked perfect, tested for 3 days. | Pedro Igor | |
| SONY | KDL-EX605 | Turns on, flashing red LED goes into protection. | LED bus. As it is difficult to find, if you want to test, just jump on the burned out LEDs. | Murai Service | |
| SONY | KDL40BX425 | It turns on normally and after an indeterminate amount of time the screen starts flashing and restarts over and over again. | Does not show any signal on the LEDs. | Fabianosfj | |
| SONY | GTX888 | the display does not light up | it was working and stopped | ||
| SONY | KDL40W605D | Flashing 6 times LED\\is good | Capacitor connected to pin 3 of the bdv9397 IC | Replace the 10 mf ceramic capacitor | Cabeça |
| SONY | KDL-40R485A | The picture appears and turns off, the LED flashes 6 times | protection activating due to weak or altered led or bad display | disabling the protection solder a 1k or 10k resistor pin 31 of the ic9500 BD9397efv to ground disables the protection | Beto2828 |
| SONY | XBR65X805G | Does not turn on or light up stand by LED | Shorted D905A and D905B (SB260 scothly) on AP-P340AM power supply | XBR65X805G | SANTOMEL |
| SONY | KDL-47W805A | Turning off by itself after a few minutes and without signals, inoperative. Missing 12v and 3.3 POWER ON voltages. Primary voltage reaching the IC MIP2H2 but without output voltage or strange voltages oscillating in some cases | Replace IC MIP2H2 or try to heat the IC for 1 minute+- to try to dilate the internal structure and restore voltages (do this while switched on until the red LED on the main board lights up indicating that 12v has returned) | WesleyMSZ | |
| SONY | KD-55X705F | Turns on the back light and turns off blinking 5 times | T-CON board | I was really unsure whether it would be tcon or display! I looked on several forums and found nothing! Finally, I disconnected the lvds cable and left the screen flat cables connected and inserted an external 12 volt power supply, so that the faulty component would heat up, and that was it! The ci ICD1 on the tcon board was on fire! I already did this on another Sony and the capacitors on the vcon board got hot too! I just replaced the tcon and ran to the hug | Rafael Sena |
