Ideas anyone? yes I know, but it's a hassle to replace right now..
Erm, yes... call IIyama ? They are a top notch manufacturer, I'm sure they'll take good care of you ! iiyama customer service helpdesk on 0844 846 0884 (or maybe 0870 224 9595 depending on when you purchased it)
Don't you even think about unscrewing anything..... really, just don't ! Take my word for it, if you don't know the first thing about repairing CRTs, DIY learning is not the way to find out how to repair them !
