Blinks stby, and LEDs blink but do not turn on, tsound is no sound or image, measuring at the main 12v power connector they oscillate | Fuse f233, which goes to the output of ci q211 near the connector, open and shorted smd capacitor on the right side of the v-com, position c20, I replaced it and it was perfect | Eletrônica Portugal | |
| CCE |
STILE D3201
|
Lamps come on and then go off and the LED on the power supply blinks | Always test whether the pins of capacitors c33 and c29 are leaking, as this will cause the lamps to go out. | ALBERI F S | |
| CCE |
STILE D3201
|
