When i click power button screen remains black but system turn on and sound beep many times and then off and again turn on beep and off. When i opened my laptop the lcd cable connected with motherboard in that place motherboard was quite burnt. I want to ask that would i have to replace motherboard or it can be repaired. Please Suggest your opinions.
babitsinghrana82 we will have to see how and where it is burned. We need to see the cable and the cable connector on the motherboard for sure. Post some good pictures with your QUESTION. Use this guide for that Adding images to an existing question It is possible that this is a bad cable/LCD assembly but it is also possible that this is caused by some short circuit either on the motherboard or the display adapter.
