I would like to ask the computer display

I would like to ask my computer monitor is Samsung's “788DF 17” flat screen, bought more than a year, the warranty is also now open is always a black screen flash is the kind of 12 seconds kind of a flash, Also with flash lights, as well as with the “whip.Whip” sound, and sometimes to be able to resume many times, the host is no problem, as it has tried to friends.There is also a very low screen resolution can not be transferred High, the higher the tune of more serious problems! ! ! How should we do??
Before the end just bought a computer in the near future, a bit out of the question, regardless of the computer company, now do not know where to go to the repair??
I would like to ask how to do this kind of situation???

This is a clear display of the fault ah, and the host does not matter.Had a 1-year warranty does belong to the outside.

unless really be able to display this type of repair, or else there will be dangerous to use, would not rule out the probability of damage to the host.

buy your LCD, I do not think that could be considered under ah.If the warranty is still Period, Samsung customer service directly.Or complaints.
