I've got a problem with the picture being dim on start up and for about 10 mins after. But when the TV "warms up" it seems to fix the problem. No adjustments have been or are made to the brightness contrast, or what have you while this problems occurs. The capacitors on the power board were just replaced via Samsung USA service rep, from where they lost class action lawsuit. The TV had this problem before the capacitors were replaced. The capacitors were replace due to inconsistent start up and lines in picture. Very common problem for this model. What specifically could be causing my problem. Some sites say bad T Conn board or L something or other cable. any ideas?
