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 |
