Ok, About once every two to three weeks, the right side of my red convergence starts to shift and I have to go into the user convergence and fix it. I have not went into the service menu yet to do the 64 point convergence. But what could be causing this. It's not that big of a deal, but gets on my nervs every now and then. It does not get off too bad, and the only time I notice it is out of wack is when letters come up on the right side of the screen. Any ideas?
