| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SONY | KDL-32BX325 LCD | Turns on, works normally, but with the keyboard inactive, and, if you turn it off for a few minutes, and activate power via the keyboard or control, it doesn't turn on. It ONLY turns back on after being unplugged for a long time. | Voltage 3.3 out at u701 with drop. | Replace u701 = g1084-33 (3v3 regulator) | NOTRYL |
| SONY | HCD-R33 | Triggering protection | Change +b resistors 100 and release the d532 diode | Replace and run to the hug | renildo |
| SONY | KDL-32BX305 KDL-32EX305 | Does not turn on, no standby or standby blinking 2x | Voltages are all normal, no inverter. After changing all the boards and harnesses, I decided to change the entire lamp panel. It finally worked, but the original inverter was shorted, requiring the inverter to be replaced or repaired. | Changing the complete lamp panel and inverter (or inverter repair) | World TV - Sorocaba |
| SONY | KDL-46EX605 | The logo appears, the logo sound appears, and then it turns off. and so on without stopping. | Missing 1.2v st1s06pur *ic1004, back varicap, side of f1003. | Check f1003. It would be good to replace IC1004 or jump 1V from another regulator on the board. | Joaomvjr |
| SONY | KLV-46W410A | TV turns on standby light turns green LCD lamp lights up and then turns off and LED turns red and flashes 14 times. | I renewed the lid and made sure nothing looked wrong. I decided to use a thermal blower to heat the power supply capacitors. The TV started working normally again. I left the TV off and turned it on again and it showed the same defect. I did the procedure again with the thermal blower and it started working again. | I replaced all the electrolytic capacitors in the c6000 group power supply. It no longer presented the defect. | ADRIANO MIRANDA |
| SONY | KLV-32M400A | Doesn't start | Smd fuse on the main board f4050+smd capacitor under the board shorted next to the ic ic4051, tsound is the capacitor, it was one of them, just follow the line that comes out of the fuse and you will find them under the board, in place of the smd fuse I put a resistor 0r47 | reginaldo moronte,eletronica junior caldas novas | |
| SONY | KV-29FS100 | Does not turn on, the LED flashes 9 times, and returns to standby and repeats the cycle several times. | Resistor r693 330k close to the power supply relays. | Replace r693 in the power supply. | Marcones de Araripina PE. |
| SONY | HCD-EX6 | When I plugged the sound into the socket it would turn on and off, only the times I turned it on, neither the CD nor the USB would work. | After analysis I found the diode d400 1n4002-a2 which is on the panel PCI it was open, after replacing the sound it works normally again. | Jonas | |
