UK Purchase from

[AdamA9]

You might be able to take it to Apple, if you can state it's a manifacture problem, and being a tinge on the screen I think you would be justified in saying that. Typically though you would be dealing with the retailer, in this instance PC World.

The Sale and Supply of Goods Act does say that if an item is faulty, and it’s less than six months old, as a rule you should be entitled to compensation from the retailer as it’s judged to have been faulty when you purchased it. If the item becomes faulty very quickly, or has never worked, you would be fully justified in demanding a refund.

Good luck

Can I just clarify something - people keep talking about Apple refunding you plus giving an additional 10% on the purchase price. This 10% (it was actually reported as 15%) is not a given - rather was being applied on a case-by-case basis to customers who had returned multiple faulty iMacs and were still not satisfied with their screen. It was also a stop-gap solution when replacement screens were not available in the UK. Apple now have a protocol in place for replacing defective yellow screens (which is a somewhat hit-and-miss affair) and replacement screens are available. Also this "rebate" was actually not so attractive as it first seemed as I think it was 10%-15% of the purchase price pre-tax. My point is I highly doubt you will receive this unless I am totally mis-understanding something here.

Regarding how you proceed:

a. Return to PC World for full refund or replacement.
b. Phone AppleCare and raise a case number then choose wether you seek a replacement (within 14 days) or get your screen swapped out. For a repair, if you're near an Apple Store they'll book you an appointment with a Genius to check the screen and then book your iMac in for repair, otherwise they'll book you with an approved independent Apple engineer.

There is obviously other consumer laws that can be applied but your case seems pretty straight forward so cannot see any issues and any need to follow that course of action.
