Got this set from a customer that described a different problem. TV boots but shows only different sized colored lines from top to bottom of the display and begins to fade. Replaced system board with no effect. Checked voltages in power supply but could not see any cycles on the pwm output. https://www.dropbox.com/...1%2021%20PM.jpg?dl=0
