Question about RCA D52W20 52" Rear Projection HDTV-Ready Television
I have a rca 52' model d52w14 the lines are not always visible but do not change with time of tv being on---model was made in 2004 and i do not have any other problems--please help
These lines are called retrace lines they are caused when the blanking pulse is insufficient to turn off the current to the CRTs (guns) during the retrace period (the time when the CRTs internal electron gun is returning to the start position after "painting" the picture on the screen). Since this is a signal problem, it will require troubleshooting to figure out why This is occurring. If you do not have a background in electronics and a working knowledge of TVs I would suggest that you have a qualified TV technician examine and repair this TV for you.
I hope this helps,
