Not sure how handy you are with a soldering iron, or if this can even be done, but I've read that the HDMI connector is a very fragile connector and prone to cracked solder joints. If you felt handy maybe you could take off the cover and look for a cracked solder joint. My guess is the joints may be very small so you'd need a small tip on your iron. Otherwise personally I really don't realize that much better(if any) PQ using HDMI vs. component. So unless you really wanted the HDMI I'd be tempted to live with only component and no upconversion. That would be your call. Another thing to think about. More than likely your machine will need service within the next few years(for whatever reason). If you just waited until another issue came up you could then send you machine in for service and get both items fixed for the same $130 flat fee. From what I understand that cost covers all repairs made, even if you had 2 issues. Just another thought.
