Rather than mindlessly going out and buying a replacement I'd rather open the TV up and see if there is anything that I can fix - has a cable come loose, a part can be replaced etc ... ? But I've done no TV DIY before so I'm not sure where to start.
The TV is well looked after, i.e. for the duration of the time that we've had it it's simply been placed on a wall mounted TV stand, so it's not as if it's been knocked about.
I've googled this group but can't find any immediate obvious answers to similar problems. Any pointers please?
