Screen turns off when brightness is too high

Well, that was my initial problem. A few months ago, whenever I had my brightness past half way, the screen would randomly turn off. What I would do to fix this issue was to reset it by holding down the power and the home button. Later on, it got worse where it would turn off if the brightness was say over 25%. I still did the reset fix and just kept the brightness low. After a little while, it got even worse than that.

Now, my problem is that the screen just doesn't turn on. If I turn it off and turn it back on, the screen would pop up for about a second and disappear. I can still use the iPod, but only Siri to play music and whatever, but the screen is completely off. I already used my warranty money on this iPod (my last iPod had a different problem so we just bought another) and well to say the least I'm completely ******. No matter how many times I reset it or turn it off and on, it does not work. I've updated it, tried restoring it, everything I could think of and I does not work. I've let it sit in the charger for a whole day and it doesn't work. I've set it out for a week to drain the battery and charged it for a whole day after and still doesn't work. Nothing at all works. If I need to open and get into the iPod itself I will do that.

Any help will work, thanks in advance.
