Hi Adam,

I have been using Cintiq's for years and normally when I have had issues in the past it is to do with the cable configuration, however recently I have had 2 24" Cintiq's that have had a power pack issue inside and everything has worked apart from the picture coming on! With one of them I sent it to them and they quoted approx £300.00 to fix and return and the other they quoted £850.00 to fix and return.

Hope this is helpful
