I purchased a Pioneer Elite 930HD (43") two years and 8 months ago. At that time prices were coming down but still quite high, 4k plus. It was recommended that I consider ISF calibration to get the best quality picture and prolong the plasma life by lowering the (kelvin) temperature set at the factory. I paid $400 for the calibration and was quite impressed with the results. After 2 years and 8 months of flawless use, the video output suddenly went out. Pioneer authorized technician, diagnosed a failure in the Media receiver circuit board, which would require a new board to be installed. Price: $425.00 for the part, $300 labor including diagnosis. Additionally, all ISF calibration would need to be redone ($400). I contacted Pioneer Customer Support arguing that some consideration was due for a part that failed after only 2 years 8 mos. Pioneer "Customer Support" was anything but. Not only is it a monumental hassel to speak with anyone in a position of authority, but if you do, here is what you are told: "Pioneer offers no support outside of the manufacturers warranty...we have no obligation beyond the 2 year stated warranty." This is astonishing to anyone who pays multiple thousands of dollars for a product that was describe as the most "technologically advanced product of its kind on the market today." While I offfered to pay for labor and recalibration, if Pioneer would supply the part, I was simply told, "There is no product support beyond the stated warranty." The fact that I had owned various Pioneer electronics in the past, and had paid a premium price for my plasma made no difference. I decided that I would write to the CEO of Pioneer regarding my disatisfaction but was advised by Mark Passmore the Supervisor of Pioneer Customer Service Repair; " That won't do you any good because all complaints are referred back to me." This attitude toward thier customers begs the question of why even have a "Customer Support" center when there is none? Oh, by- the -way, I was told that the 2 year manufacturers warranty applied only to manufacturing defects. So even if you have a problem, Pioneer wil put you through the maze of proving that the problem was really a result of defective manufacture and not simply normal use. That means you have to have a Pioneer "Authorized" repair facility diagnose the problem. Naturally, they understand that if they want to retain their "Authorized Repair" status, it is not thier best interests to find factory defects in Pioneer products. Frankly, my experience has turned me against Pioneer. I will never purchase another Pioneer product and I urge other consumers to beware of Pioneer. You will get no support if your product malfunctions outside of warranty and will have to "prove" that any problem is the result of manufacturing, (almost impossible).
