I have an Older Samsung 52" DLP and I have lines going through the screen when connecting anything using the A/V Inputs, the composite looks great. We purchased the TV from family and they never had the problem. My Sister-in-law has the same TV and we played Wii on it with no lines but mine had lines on it when connected through A/V (now it is composite). Can a/v inputs go bad? I have tried to upgrade to better quality cables to no avail. Any suggestions are welcome. The only things connected through the A/V is PS2 and DishNetwork (with only coax, A/V, or Svideo outputs) both have lines with any connection.
