Hello. I have a Samsung UN55J6201AFXZC LED TV that the screen has gone very dark. If I use a flashlight against it or have it angled to the sun just right I can make out the picture in grey tones. I've attempted unplugging overnight and re plugging in and it hasn't helped. I tried a tv reset and software update and neither worked. From everything I'm reading online it sounds like I need a new backlight inverter, just wanted to make sure that seems correct? I tried a chat with Samsung and they were no help, and since then I've been unable to see the grey picture, but the tv still has power. The TV is only 2 years old, although it gets lots of use as I leave it on for my dogs during the day. Any advice?
