This sounds like the backlight board on that side has failed or a failed led strip in the area of the panel where the screen is dark.

Customer: replied 4 months ago.
I don't think it is leds because the dark is about 15 inches top to bottom rather than spotted dark spots. the overall picture seems a little dark also
Customer: replied 4 months ago.
are you still working on this
Expert:  *ElectronicsTech replied 4 months ago.

yes, that is the symptoms for the backlight failure.

Customer: replied 4 months ago.
can I buy the part.
Customer: replied 4 months ago.
are there leds and backlight?
Expert:  *ElectronicsTech replied 4 months ago.

yes, you can remove the back panel and see if the backlight led strip in that area is lit.

Customer: replied 4 months ago.
Whe I remove the plastic back cover there is a metal cover .
Customer: replied 4 months ago.
if the leds are not lite does it mean there bad or what powers them is bad.
Customer: replied 4 months ago.
Do leds strips run vertical or horizontal.
Expert:  *ElectronicsTech replied 4 months ago.

if it is one section it is usually that section of led strip is bad.

Customer: replied 4 months ago.
If they run horizontal that would mean several rows all went out at the same time. How do I know it is not the power source.
Expert:  *ElectronicsTech replied 4 months ago.

yes, they run horizontal. It is possible that the board has failed however it is most likely the strips.

Customer: replied 4 months ago.
I m sorry but that don't make sense that all those rows would go out at once unless there was a power surge. If they were going out a little at a time then I would agree. I still think it is either wiring that powers the leds or the power source.
