no screen backlight

Hi, i know it's an old issues and few solutions are posted out there, but none worked for me.
symptoms: phone turns on with sound, vibration and top led, menu and back buttons all lit, but screen black, it even responds to touch from the sound it gives.
although, i noticed a way to bring the screen alive for sure is to plug usb cable to to charger then turn it on and screen comes alive.
i don't think it's hardware problem, or flex cable disconnected, because when it turns on it works flawlessly, and as many know dismantling the s5 to check is a real pain.
and if it's a software glitch, is the MM update that's coming out will fix it?
anyone with real knowledge of this issue and ow to fix it, please help!!!
