Sony Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SONY | KD-49XD8305 KD-43XD8077 GN2TR | No power / no response / reboot | Check voltage in ic402, if no +5v replace ic402 | ||
| SONY | KD-49XD8305 KD-43XD8077 GN2TR | No power / no response / reboot / u-com failure | Check voltage in ic401, if no voltage in pin 11, 12, 13, 14, 15 replace ic401 | ||
| SONY | KD-49XD8305 KD-43XD8077 GN2TR | No power / no response / reboot | Check voltage bet. gnd and ic1000 ng | Check and replace c413 | |
| SONY | KDL-40EX525 | Does not turn on red LED flashing 6 times | Short in backlight line power supply | Replace two transistors that were shorted, these are located before the backlight transformer. Tsound are two resistors in the transistor line, test if they are open, in my case one was open. | ELETROSANTOS |
| SONY | MHC-EX66 | Mysteriously turning off by itself every now and then it goes crazy going into demo mode | Problem in the protection line v-mini pin 34 of the micro ic302 | Disconnect pin 15 of the cn307 connector that connects the device's front plate with the power supply board, the defect in this case is the processor, the option and leave it turned off | charlotniu |
| SONY | KDL-46EX650 KDL-52EX705 KDL-40EX705 KDL-46EX705 | TV turns on and the Sony logo appears, but then turns off and the red LED flashes 6x | Defect in the 0.5 SMD PS6800 fuse located on the power supply board, close to the LED sockets in the corner of the board | Replace it, I replaced it with a common fusifel and it worked. | Eletronica Muniz |
| SONY | CECH-4211A ADP-160AR | PS3 in stand-by, pressing the power button goes to green LED and then goes to red LED again. sometimes dies in black-out | Defect in the power supply, without 12v, and when turned on, sometimes the 5v drops too. | Power supply defect, without 12v. When opening the power supply, replace the dda001ag. it is located under the 12v transformer in position ic50 | SV Eletrônica |
| SONY | KDL-40BX425 | Does not show voltage 12-24 volts flashes twice. | Leaky transistor q931 and faulty ic 902. | eletrofepar | |
| SONY | 32R435A | Does not turn on the standby | Shorted capacitor on the right side of the crystal just above the medi/tek processor | Check if it is getting hot with your fingertip. | Mariano |
| SONY | KDL-32EX525 | TV doesn't turn on, doesn't even show LED STBY | 1) capacitor shorted on the tcom throwing the 12v to gnd, incredible because the tcom fuse didn't burn, it burned one of the power mosfets on the power supply board (q6410 - it's an 8118) leaving the tcon_vcc_12v connected directly. 2) after repairing the power supply board, the TV still wouldn't turn on. the 3.3v stby voltage was ok, but the stby led did not light up. I checked that the board has a 1.2v stby regulator that was without voltage, I removed the regulator and 4 capacitors from the line but none of them were shorted, I tried feeding the main board with 3.3v and 1.2v from a power supply. bench but the LED didn't light up. When I connected 1.2v from the power supply to the line, initially tsound was a short, I slowly released the current, increasing the voltage to check wsound the short was and suddenly the short disappeared. | Apparently the short was inside the main IC of the board, when I released the current on the 1.2v line, what was shorted inside the IC burned and released the short. just changing the main board. | 2000 |
| SONY | MHC-EX88 MHC-EX88 | Low sound | It is inoperative without 6v pins 3.5 of ics 600 and 601 | Replace c612 100mf/10v short | MEKCORADIO |
| SONY | KDL40BX425 | TV kept appearing on the screen, warning pen driver connected. | Ci that is behind the u112 usb input with 5-pin smd leak.ci | Replace ci u112 | Eletrônica Moisés |
| SONY | 40BX425 | The stand by doesn't turn on, it doesn't turn on, but it has 5v from the power supply | Ci 701 regulator 3.3 v | Mariano | |
| SONY | KDL40BX425 | It kept appearing on the TV screen, warning that tsound was a pen driver consuming energy. | Change the 5-legged ci, behind the usb input. | Eletrônica Moisés | |
| SONY | KDL-46R485A | Does not turn on, LED flashes 5x | I isolated the faulty display side (I removed the flat that connects the two sides of the display) feeding it with an external power supply I threw 10v at the avdd, ca30 started to smoke | I removed it, the TV turned on, perfect image. | Maurilio |
| SONY | KLD 32R305 | Turn on and off 3 times | Bad led bar | Customer in a hurry, a 32-inch Samsung bar was adapted and it worked | |
| SONY | KDL-46R485A | No standby signal | The larger smd capacitor close to ic6004 was shorted, f6002 open | Replace capacitor and smd fuse | Jamis |
| SONY | KDL-40BX455 | Turns on, red LED lights up, then green LED and returns to standby, red LED flashing 6x. | High voltage transformers changed on the driver board. one leaking loudly and the other open. | Replace transformers t109, t110. | Arock |
| SONY | KDL46EX725 | Does not turn on red LED blinks twice, sometimes turns on after several attempts. | On the power supply board, locate 2 mega resistors, scrape the glue underneath all of them. | Carlossbs | |
| SONY | MHC-GTX787 | Only turned on with remote | Change all micro keys. | Luciano |
