sanyo purchase a 50' flat screen tv, it stops workin within a yr. call corp no one was able to help, they say i have no warr, therefore they will not do anything about it forrest city Arkansas

When warranties are up, you're on your own.  Although the title of your post says it stopped working within a year, the body of your post contains the heart of the matter.  

If a company warrants their TV to be free of defects for one year, why would you expect them to fix it after a year and a half?   If they wanted to do that, they would have called it an 18 month warranty. 

I often wonder how people can be so confused by this concept. 

That said, there is value to your post.   It's always nice to know what brands are having failures just after warranty.  It's also a good idea to check out such reports before buying.   Doing so made a big difference when I bought a big screen a few months ago.  The one I intended to buy turned out to have a chronic problem with power supply failures with just over a year in service.  Thanks.
