Hello! First I want to say that this is my first post and am glad to be aboard on this fine Forum!!! I purchased a Rca hd50lpw162 back in Feb and have since been trying to get a replacement part for it and just recently Rca told me that they can no longer get what I need. So they are offering me a swap.. and from what I can tell the 175 is a good choice (from what they have to offer). However I have not been able to find too much on the set, so I was wondering if it is indeed a better tv overall. I assume it is since it is using the HD4 chip instead of the HD2+ but I just wanted to know if any of you could clarify for me?
