I am based in the UK and have a first gen with lg screen, posted on here before and followed since owning my MBPR 15".
I've had issues from day one with IR, made 3 trips to genius bar, only for them to run the test and tell me it's within spec, although it has got worse over time (since jan 2013) they still keep telling me this. Calls to the support team have been very frustrating, 7 or 8 calls and not once have I managed to get this resolved, the one time I got to speak with higher management about 2 months back I was told that I had more chance of getting compensation from the store I bought it from or the credit card it was purchased on than getting a replacement screen (even under the manufaturers 12 month warranty), then I had an email linking me to the IR Solution page on the apple site..... from that very same manager.
The last call made this week proved more fruitful but will beleive it when I see it, the lady on the phone saw that I had spoken with management staff and could not beleive the response I was given, she has set me up yet another genius bar appointment for this week and passed all notes on the store. Let's see how this one goes, any tips appreciated!
To be honest I am not holding out much hope, IR shows after 1 or 2 minutes and takes longer to dissapear, the dock also had IR ghosting now which never happened before, the test is not really in favour of normal everyday use for me as I used to use my mac for designing and photography. I say 'used to use' as I've actually resorted to not using the machine and use my pc for all work, the most the mac gets used for is the odd movie.... getting my monies worth from a £2,000 machine!
Oh and also out of warranty the end of November but am completely against paying for apple care at £270 over another 2 years if they can't/won't support my problems since purchasing the machine, what trust have they filled me with!!!
