SONY Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| SONY | MHC-GRX9900 | Display lights up very weakly | All micro and display voltages are correct | Sebastião | |
| SONY | MHC-GTR6 GTR8H | Turns off and LED flashes | Fault on the thermal detect d1310(maz8091) dz9.1v line, you can put dz10v. | samuel leite | |
| SONY | DZ-295 | Does not turn on display off power supply ok and display too | Lack of voltage ever 3.3 =e3.3v | Look for the diode d503 it receives 4v and releases 3.3 I replaced it and the problem was resolved. | FLIPFLOP |
| SONY | HCD-EX660Z | Goes into protection after a few seconds | Solution is to change the sound output IC | Replace the sound output, remove it from the power supply and you can hear the sound on the headphone input directly from the pre | |
| SONY | KLV-37NL14A | Turns on and then turns off by flashing red LED 6 times | In my case it was a fuse on the reverse board, position f1, close to the middle screw | Note: this TV has two versions. the invert plate for this is "fr-4-86-py" | Mario Moreci |
| SONY | KDL32R305 | It turns on, then makes noise and turns off and flashes 6 times, after changing the LED bars it was the same thing, because when changing new bars you have to solder the bar fittings as they give very poor contact and represent a defect on the board | Weld bars one by one into the fittings | LORD | |
| SONY | KLV-32S300A WAX3 | Negative image / inverted colors | U8 as34-g on t-com board [it is a 14-pin integrated (7+7)] | I used an el5420crz from another t-with scrap | Baguatech |
| SONY | HP319 | One of the channels is lower than the other and when it increases, it pops | It was the 2sc 634 transistor, I researched a replacement for it and found it | The bc547 and it didn't help, so I put the bc337/40 and it was great | Celso |
| SONY | XBR-65X805G | Doesn't start at all | Electrical network oscillation | Changing the diode d905b in parallel d905a ideal to replace both | loja Inogamma |
| SONY | STR434 | Dead radio | Device burned the radio with lightning | Cx178, and to ensure it is well adjusted, replace the trimpots as they are often oxidized, then the regulator turns off and goes out again, sound it only became unstable after changing them. The memories vary, I did a general cleaning of the entire dial. | |
| SONY | KDL-32EX605 KDL-40EX605 KDL-46EX605 APS-272 1-881-774-13 | Doesn't start. It has 3.3v but does not activate stand-by. | Diode d6303 next to relay ry6001 with leak or short | I replaced the diode, I put the un4007 in its place | Eletronica M |
| SONY | KDL-32R305B | After turning it on, it restarted and then it kept blinking 6 times, the LEDs were changed but it kept turning off when testing without the display, thank you very much for the tip from the colleague above who says that if you don't connect the TV with the TV it won't turn on, thank you very much I was breaking the head sound a hug friends. | The LEDs were replaced and the TV was 100% operational. | Eletronica Centenario-RS | |
| SONY | KDL 40R485A | Turns on and off with LED flashing 5 times | Short on avdd line on v.con board | 10mf smd capacitor in short position on the cd7 board. | jose carlos |
| SONY | HCD-EX66 | Sometimes it turns on, sometimes it doesn't. | Check 22v d932 zener. change c937 47x50v. r937, 100k r939 and 4k7 without measuring. | Régis | |
| SONY | KDL-46EX505 | No image with sound. black screen. | Bank of resistors next to the lvds cable connector on the main PCI. | Replace with air station. | RYK |
| SONY | KDL-32EX715 | Doesn't start. It has 3.3v but does not activate stand-by. | Diode d6303 next to relay ry6001 with leak or short. | RYK | |
| SONY | KD-49XD8305 KD-43XD8077 GN2TR | Hdmi no picture, hdmi not working | Check ic1000 of | ||
| SONY | KD-49XD8305 KD-43XD8077 GN2TR | Hdmi no picture, hdmi not working | Check r3646, r3644. r3645(1k 1/16w) r3647 (1/16w) | ||
| SONY | KD-49XD8305 KD-43XD8077 GN2TR | No power / no response / reboot | Check voltage in ic601, if no +1.5v ddr replace ic601 | ||
| SONY | KD-49XD8305 KD-43XD8077 GN2TR | No power / no response / reboot | Check voltage in ic606, if no +1.05v m2_a_2 replace ic606 |
