Please check what t- con board is similar with your tv board to order it. If you are not handy with electronics stuff repair then local tv repairman will help you to replace t-con board that might solve your tv picture problem.
Thanks.

select the correct tv format, check your manual

The problem may be not in your TV but in your receiver, if you use a cable or satellite receiver. Sometimes those also have similar settings for picture mode - it's rare, but I've seen it.

If not, then it must be tv's zoom mode is just set to something other than "standard".

Here's a web site reveiw of the TV:

And here is the TV manual download:

Since you have another TV with the same problem you can try using an antenna(indoor model ok) to see if the cable is causing the problem. If not return TV before the warranty expires.

The set may not be at fault. If you are on cable some channels are still in anolog and some are digital. if you are on a nolog channel the picture will look preaty bad compared to the digital ones.

what kind of cables are you using? Make sure you get the HDMI cables. Also, the S and V Sony series only have a refresh rate of 60Hz, which means that when you get fast action scenes or when people are moving, you will see a very noticeable blur. There really is nothing you can do about this. I had a V series and immediately returned for a W series, which has a refresh rate of 120 Hz. Sometimes, you can still see the pixelation, especially if the TV can't handle the response time, but it is definitely less noticeable than the other series.
