The particular error code can mean a couple of different items of concern.
The video cable running from the motherboard to the LCD can have a short in it.
The video cable point of connect to the motherboard can have a damaged pin.
Unless you feel very comfortable taking apart your unit - and your not under warranty - this is going to have to be an issue that a trained technician resolves.
I apologize for not having better news about this, but sometimes hardware issues have no resolve, except to notify of the need to service the unit.
Please feel free to ask anything at all you want on this issue.
Take care and God bless.
