Hi Bill
I had same problem with a Medion 17" TFT Monitor MD 30917 PN, which was still under the Medion 3 years warranty. Rang Medion Sat 12 July, they collected it my courier Tue 15 July, repaired it and delivery it back by courier Thur 17 July.
They tell me they have had to repair the power supply board and logicboard. It now works perfectly coming on straight away.
Try ringing them on 01793 715698 and see what they can do.
