Sony KDL50W800B or Samsung UN50H6400
We used to have a Sony XBR4 that we got about 5 yrs ago. A few months after the extended warranty the tv started getting these lines and started to black out. Come to find out after the fact that that particular model had issues. I found a sony forum that was about those issues and sony was offering a 15% discount towards a new sony tv. My wife and I were left with a bad taste towards sony after that. So we picked up the Samsung UN50H6400 for just about $850 from ABT a few days ago but now we are both starting to have doubts about the quality of this tv. I know it's not a higher end like our last sony was but after 5 yrs we thought the technology would at least offer the same quality as the XBR4 did. We really loved that tv, just not looking to spend another $2500 for a new tv right now. After looking around, it seems the sony w800b is the best option in terms of pricing with the samsung h6400 series. Im not sure if I just dont have the settings down properly, it just doesn't feel like the picture pops like the old sony did.
We are looking for thoughts regarding these 2 models and if we should reconsider going back to sony. ABT said they would honor the 15% which would bring the price down to about what we paid for the samsung.
