Query: Can't review TV but can confirm Amazon customer service is good.

1st set that arrived was obviously a refurbished item and the state of the packing was terrible - the foam case that normally goes around the TV was in bits and haphazardly packed in.So it was no great surprise to find out that the TV didn't work at all!I ordered a replacement from Amazon and was pleased to see that a) they sent the 2nd unit whilst the 1st unit hadn't reached them b) they upgraded to 2 day shipping.Unfortunately, the 2nd unit had a terrible picture & after calling Philips they recommended sending it back so I did.I ordered another replacement but Amazon cancelled the order themselves because they didn't want to send me another dud. They gave me my refund quickly.
