I don't have an idea what "hill bunker" is, but usually a device beeping when it shouldn't, and not displaying anything, is an indication there's something wrong with the device. You should contact vendor for help.
Have you tried checking the cables if something is wrong with them? Sometimes the cables can get distrupted and get accidentally unplugged if it is just the cables. Is the monitor turned on or off whenever it doesnt want to show anything?
