Question about Hitachi 42PD7800 42 in. HD-Ready Plasma Television
I have a Hitachi 42PD5200 plasma that has developed a thin red line about 4 inches from the left hand side of the screen. There is another one at the extreme edge on the same side but this does not really affect viewing. The line is at the same position as the left hand edge of the picture if you are viewing non widescreen. I have checked all user settings but it is still there. Any suggestions would be appreciated.
According to what i could find, there is no way to actually SOLVE the problem, this is what i did find; The plasma display panel is lighting the phosphors by the discharge of internal radiation. Depending on the screen contents, in rare cases this may cause vertical stripes to appear because of failure to light. Please note that this is not a malfunction.
