LG 65UJ630T-TA Screen dimming issue

[ironmonkey]

I have posted here before about how disappointed i am with the LG TV that i paid a lot of money for. About how the TV did not really do most of the things that i was led to believe that it could do before i purchased the TV. I ended up then paying extra for a TV box to actually get the TV to do what i was led to believe that the TV could do and how i effectively paid for a very expensive monitor.

Now 4 years after buying this TV and not actually using it much, maybe 3 - 4 hours each day, i turn on the TV and low and behold, there is another issue. This time the screen is very dim with the very low brightness, like the brightness setting is turned down to around 30 - 40%. After trying to change all the settings, including energy saving, turning off the TV and disconnecting it from the wall, waiting 15 minutes and turning it back on (yes that was advised) and resetting the TV back to the default factory settings, the screen is still very dark.

After searching around the internet, it looks like there is an issue with either the power supply to the TV (LED) or an issue with the backlights inside the TV not lighting up. So it looks like its now going to cost me at least another $100 plus to fix this already expensive TV after only a few years of very minor use.

I was hoping that there might be someone here that might have some information that i might have missed and that might help with this problem, i have pretty much tried most things but with no fix (changing the picture settings slightly change the brightness, but its totally washed out, or the colors are just nasty).

Anyway thank you in advance.
