Hello,
I have a Sumsung LCD (Model: LE40R86BD) and after 5 minutes approximately
starts to flickering about one two times and after some time stars the same thing again. There was one capacitor that was blown and I replace it. I measured all the voltages at CN801 and are OK. When the display turns off the "POWER ON/OFF" signal goes low (0Volt) and after 3 seconds come back high again. Maybe after some time something get hot and do that flickering? Any ideas for what to looking for?
