So after happily owning my KP51-WS500 for 11 months the flicker has begun. Sony has a bulliten listed on their page regarding this. They are extending their manufacturer warranties on the affected sets to get them repaired at zero cost to the customer. I called their service center and after describing what is going on and referencing their page, they opened a ticket and will be sending out a tech to perform the repair in home zero cost to me. Will post to this thread after the repairs to report on the results. Frustrating that Sony is not contacting customers proactively. Those that just chalk the flicker up to a bad TV signal or what not are not getting what they paid for. :-/ Go here --> products.sel.sony.com/SEL/service/conselec/news/flicker.shtml Hans.
