Jsd first you need to help us to help you by identifying the display. Your monitor is a A1083? As for your duirect question, that will depend on where you are and what cables you think you need. Explain the flashing some more....

Yes it is A1083.

The flashing does not happen all the time. Some times its is a mix of grey fuz and sometimes the screen blinks and its a mixture on and off usually for about 3/4 mins at a time. It will then stop for an hour or 2.

Thanks
