Ok so, I have a pretty horrible problem with my monitor (HannsG 28").
Following using the monitor and switching it off, it must be powered down for roughly 30 minutes before I can use it again. If it only used briefly (one minute or so) you will be able to switch off and on again without issue. However if you use it for any longer, upon switching it off and on you are presented with a pure white screen or a mash of colour.
As I'm sure you can imagine this makes using the screen fairly annoying and upon installing a program or update which requires a restart.
Firstly, any ideas what's wrong with it? I have had it replaced under warranty and it does exactly the same. They claim however it's not a common fault and should not happen again. Incidentally, it is still under warranty (onsite) but they say they have no stock for now so want to repair.
Secondly, it seems to me it may well happen again, I know its a long shot, but any chance of a refund? I dont want a better monitor, I just want one which works.
