I have a LG Home theater set...which wont switch on.
1. When I on the main power ..a red LED light come on. 2. When I press on the power on button, the red LED turns green briefly for 1 sec and switch back to red. The whole unit just switch on briefly for 1 sec. 3. When I off the mains the red light stays on for almost 5 sec which show a good capacitor. I have check the transistor for bistable circuit and they seems OK. Any other ideas? |
