Summary: We purchased this TV from a local retailer on April 3, 2013. We installed it that weekend 2 days later. Only 11 days after that the dreaded 13 red light blink showed itself and the tv quit working. Reviewing online customer reports this as the A board failure. Some customers even had other failures for the P board. We were lucky enough to have the 15 day money back return for defective products. We have been true Panasonic buyers for years until now.
