Over the past couple of months my tv screen has been flickering. That is the best way I am able to describe it. It doesn't do it all the time just maybe 90% of the time. It didn't always do it that much it just seemed to start doing it that much lately. It does it on all inputs that I have tried, HDMI and PC. I have had my tv since June of 2006 and I haven't change the bulb and I was thinking maybe that was the problem. I am going to buy a bulb tomorrow or the next day and I just wanted to see if I am making a good decision by buying it. Does anyone know if it could be another problem? Thank you very much for your help.
