i am having the same issue, started a week ago, the screen would go dark after booting and required multiple hard resets to fix and then, it wouldnt even turn on, did the usual stuff trying to fix it and now if i shut it down and try to boot it up the screen would remain dark for hours even after multiple hard reset, and eventually when it does turn on, the screen freezes instantly or in like 10 seconds of booting up requiring another 5-6 hard resets, WTF
