Packard bell are the only company to pull this stunt and it annoys me to the extreme. I'm a mobile IT engineer and I come up against this many times. The answer is yes I'm afriad you will have to get another if you want to power that screen.
Does your VGA (monitor)cable not have any sockets on the plug per chance and a box on the floor running from it and the other end to the mains. As it seems with later I-Med's that they have finally realised that powering direct from the psu kills the psu off early so new screen or replacement psu that will die in the same way...sorry for bad news
