|
|
Hi all,
Samsung UN40F5000AF
40" TV
I have had this TV for three years. A few months ago, I noticed a dark portion of the screen. It is dark in the upper half, however still bright about an inch inside the frame. It looks like a glowing dark box (see picture). After searching a number of forums, I wasn't quite sure whether people were having the exact same problem as I was.
I have tried bending the frame back and forth as others have suggested. I am at the point where I want to open the frame up to see what's going on inside, but I was hoping you all could help me find out exactly what I'm looking for when I do that. Thanks in advance.
-Sonny

Yep, you have a few strands of backlight LED that have failed.
If this is the model I am remembering, if one LED fails, the whole string fails horizontally. I think the top two strands are also in series so if any one LED on either strand dies, both strands go dark. |

Thanks for your help, guys. Probably not worth getting it repaired, correct? |

Unless you're good at careful disassembly of panel.
Make sure the LED back light settings are lowered from 100% 'Default' on your next one. |

It's all just a matter of your perspective. I'd gladly repair this one. |
