Monitor cable fried, how do I tell if anything else needs replacing?
Background: I received this Netbook second hand and it has had a short in the monitor cable for the entire time that I have owned it (about a year and a half now). It has been annoying, but has not actually interfered with my use of the device.
What happened: Just today, after having spent most of the day using it plugged in, I went to use it without the cord and it wouldn't turn back on. I tried once or twice without it being plugged in and nothing. I then tried plugging it in thinking the battery may have gone bad. It started to turn on, then there was a small puff of smoke accompanied by the smell of burning and it shut back off and remained off.
More info: I have opened up the case and it is quite obvious where the burn happened: where the short in the cable occurred the casing has worn away and the wires in the monitor cable made contact with part of the metal hinge in the case. There is no other visible damage to any of the other components.
My questions are as follows:
How do I tell if there is anything else that was damaged when the cable fried?
Do I need to replace the entire motherboard, or would replacing the monitor cable be enough?
Is it possible to replace just the cable without replacing the whole board?
Here is an image of the damage that I can see:
Is this a good question?
