The clock on this TV has always ran slow losing 2 or 3 minutes every hour. I exchanged the first TV for this one because it showed the same problem. It's the clock used for on screen display, and switching the tv on at a preset time. I doubt it's adjustable but where is the chip and driver timer crystal- it may be worth changing. Or better yet, has anyone come across the problem and got a solution? thanks!!!!
