Sony Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| 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 |
