The tv is the RCA Scenium 61 inch DLP. I think this picture has gradually darkened over time. We bought this tv about 3 years ago. Would the bulb going bad yield a darker picture? Also, there have appeared rolling bars - they're pretty faint, but on screen images where there isn't a lot of color contrast, i.e. if the color is pretty uniform across the screen, they're easier to see. They start at the bottom and gently roll upward. Could these problems be related? Are they due to a bulb that needs changing? Thanks in advance!!
Yes, the lamp will gradually get darker as it nears it's end. The rolling lines sounds more like the set is on a local channel for the cable hook up. If your local area has a channel 3 or 4 live terestrial broadcast simply tune the cable box output to the other one, the same for the tv.
If this is cable/local broadcast issue it will go away in Febuary when the NTSC broadcast ends.
