Question about Samsung HCL4715W 47" Rear Projection Television
Our tv has suddenly developed thin lines across the entire screen
the lines appear to be either red or blue depending on the background colour
You could almost describe it as a strobing effect
perhaps what you would expect to see if there was some sort of elecrical interference.
we have turned off all nearby appliances but this made no difference neither did plugging it into a different power circuit
also tried manual convergence and perfect focus
te tv is approx 4.5 years old
