Just got 3 new DLT 5085 off ebay for a mates reno. They are factory sealed units all with manufacture dates of Sept 2009. All work perfectly with the exception one has a vertical colum of pixels missing. I have reset the unit, powered it up and down etc etc and it definitely has a repeatable colum of pixels missising. What is the situation in this case with regard to warranty? Given they were manufactured in Sept 2009 wouldn't they still be under warranty. I bought them from a couple that had them left over from a large house they recently built. I have asked them for a reciept which they tried hard to find for me but were not successful. I paid nearly 0 each which I thought was a fair price for them given they are new. Appreciate some guidance. Regards, Fleetz
