We appreciate your interest in this television. No indication is noted, in your post, as to what model is actually owned; rather only referring to that which was referenced in a previous post. Also, we cannot determine yet, what the price of the upgrade will be, as we still have no indication of the actual cost of the needed part, nor do we have any control over technician pricing. Please contact our Customer Interactive Center at 800-243-0000 for information on this matter.
