Sony Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SONY | ADP-240AR AA | Turn it on normally using the jumper, but when you inject something to work on the 12v output, the power supply dies | The relay does not hold, it opens as soon as it ejects | It was just replacing the ic41 (1608b) | DEO ELETRÔNICA |
| SONY | MHC-EC68USB | All functions locked | Some keys leaking or shorted | Replace all keys | DEO ELETRÔNICA |
| SONY | ADP-200ER BA | Giving 9v and varying the saying of 12v | Photo coupler ic51 | DEO ELETRÔNICA | |
| SONY | ADP-200ER BA | 12 volt output oscillating a lot | Driver com broblema | Replace the same (reference t2) | DEO ELETRÔNICA |
| SONY | KV-29FX20E FE1A | Works for a while and then goes off, blinks twice | Ph 601 tcet1103g rusty between pines | ANTMACARICO | |
| SONY | KDL-40BX425 | Green LED lights up then flashes red, without 12v and 24v | 15v zd971 with leakage | Replace diode | Cleiton |
| SONY | KDL.. W955A | Turns off and flashes 4x | Leak in the LED bus/or defect in the inverter | Remove Q4001 (SMD switch) from the inverter board and close pins 4 and 5 of the CN2001 connector (which goes to the power supply) | Elias Florencio |
| SONY | KDL-48W655D | Does not turn on, standby LED flashes red 6 times | Processor bga solder | Reballing | GABSENS |
| SONY | FH-G88AV | Turns on, no sound, graphic bars do not work, noise when increasing or decreasing the volume | Regulator IC1003 of 7v with 0v at the output, changing it, the device does not turn on anything, the regulator heats up until it burns again. | Ic 901 defective. ci of digital volume. replace of 7v regulator ic-1003 and ic-901 m-62427fp device works perfect again | Josimar Afonso |
| SONY | KDL40BX425 | When the TV turns on, the power on light turns on (green LED). It has no functions and if it turns off, it doesn't turn on again and most of the time it doesn't even light up the standby LED. Just unplug it. | Ci u 701 changed. It has to be 3v3. | Replaced the ci u701. the problem was solved. | DANGRA ELETRÔNICA - SÃO PAULO |
| SONY | ADP-160AR AA | Without 12 volts | When you turn on the power supply, it goes up to 5v | Ic 81 ( das2 ) | DEO ELETRÔNICA |
| SONY | KDL48W655D | LED blinking 5 times and won't turn on - two TVs with the same defect! | After several tests with two TVs and the same defect, I found that one LED on each TV took too long to turn on. | I replaced the bus with the problem and the defect disappeared. I would like to point out that when testing with the LED tester it was not possible to identify the defect, only by opening the TV. | Eletrônica JJ |
| SONY | MHC-GP3G | Entering protect e04 | Defect in ic1405 njm2903v | Replace the same | barbadinha |
| SONY | KDL-32R485A KDL-40R485A KDL-46R485A ITC2 | TV turns off by itself and standby LED blinks 6x. | Defect in the ci bd9397efv responsible for the backlight operation. In my case, I redid the connectors on the rulers, but the TV still activated protection. | Check the remaining voltage on the negative of the LED banks. the correct thing is to have between 0.8v and 1.5v left. Above that, the TV can trigger protection. If tsound is no defect in the rules, replace the ci. | rafaelmoraes99 |
| SONY | MHC-GPX7 | It doesn't turn on anything, not even stand-by. | Power supply apparently ok, with a voltage of 7v (stand-by voltage). the problem was in the ac-det line (sector that informs the computer that tsound is ac voltage coming from the primary). In my case, it was a defect in the power supply's PC702 photocoupler, which was not activating the base of the Q702 transistor (SMD connected to pin 3 of the power supply's CN3 socket) | Replace the pc702 photocoupler that goes into the power supply (if the base of the transistor q702 becomes polarized, the problem has been solved) | Gênios Eletrônica SJ SC |
| SONY | KDL-46EX405 | TV turns on, the logo appears, turns off and starts all over again | Smd capacitor near the i.c. 9301, close to cn 2600 | The capacitor was shorted, tsound are two more in parallel. | Ricardo Fortes |
| SONY | KDL-46EX405 | TV turns on, the logo appears, turns off and starts all over again | Smd capacitor near the i.c. 9301, close to cn 2600 | Ricardo Fortes | |
| SONY | HCD EX8 | Falls into disrepute and doesn't start. | Secondary power supply diode d 018 open | Replace d018 | Jsf |
| SONY | KDL-32BX325 | TV turns on whenever it wants | Power supply voltages ok, but on the main board, the u701, which is a 3.3v regulator, had a low voltage (1.3v). it was just a matter of changing and running for the hug. | ||
| SONY | KV-29FA210 BA-5D | Dull, increasing screen gives retrace lines. | Resistor 33k aberto r547 | Resistor replaced and defect corrected. | Tarcisio Brito |
