Hello, my 46 inch LCD Dynex started having issues with the picture a couple of weeks ago....the picture would disappear (still had audio though), by changing the channel a couple of times I could get the pic back. It happened several times over the next couple of weeks, now when I turn the TV on I get absolutely no picture at all, just audio. I called Dynex and they had me power the TV on and off a couple of times and then told me I was out of luck as the TV was 8 weeks over the 12 month warranty period. Thanks for nothing Dynex and Best Buy (I think they should change their name to Not Best Buy!!) Any ideas would be appreciated.
