No power to my Digimate L-1715

Hi … I had my digimate monitor L-1715 in storage. When I tried to set up the system there appeared to be a power problem as the picture flickered very noticably and it was impossible to work with. Now, if anything, the problem has worsened. The monitor is out of guarantee. Any inspiration would be welcomed. Regards,
