5 Samsung UNF series TV: why screen flickers black (backlight failure)?
My Samsung UN40F6300 has been repaired three times. It's now out of warranty, lightly used, and has developed a flicker. The screen quickly fades to black for less than a second, every 5-30 seconds at random. Sounds like a backlight is going out. Can anyone help diagnose?
Good info on backlight inverters is here: https://www.youtube.com/watch?v=bHPJNVe4... (ShopJimmy.com).
