I have had a Sony KP 61HS10 for about 4.5 years, but it has a problem with HD signals. The picture looks great, but every once in a while, the HD input will flash and lose the picture then pop back in. I have had Ultimate Electronics try to fix it about 5 times, with no luck. They finally have decided to replace it. They said they will replace it with a Mitsubishi WS 65615. I looked at the specs on this, and it looks pretty good. I was just wondering if the picture will be better than my old Sony. I have an HD Tivo that will be hooked up to it receiving OTA HD and DirecTV HD. It will also be used for SD Directv signals. I haven't seen this set in action, so I am a little wary of just saying go for it. It would be a brand new set replacing a 5 year old set, so that seems like a good deal. I appreciate any advice or warnings about this.
