I have the above tv which has a built in blu ray player. All of a sudden the blu ray player no longer recognises discs. I rang sony who told me to install the latest update but I don't think this will make any difference. It has been working fine with the current software version. If it is a prob with the built in player then an update will not make a diff will it? Also I have downloaded the latest software version but the tv doesn't recognise the USB device when I turn it on. I only have a memory car reader so I've inserted the mem card into that and then plugged it in to the tv via the USB. Can I use a mem car reader or does it have to be a USB flash drive thingy. I did buy a blu-ray cleaner disc but remembered after I'd bought it that the player wouldn't be able to play this either in order to start cleaning it. Any ideas?
