“Cause for green picture with wavy lines My 55" Dynex is about 3 years old. About once every 3-4 days the picture goes from excellent to greenish wavy lines. Turning the TV off and back on corrects this for the next time period. What parts might need replacement to correct this? A previous post also reported this but the only response was to have it repaired if the problem persisted. What is the cause of this problem?”
