[Note Edge Q&A, Help & Troubleshooting] ThEliteCommando:
So my T-Mobile Galaxy Note Edge (SM-N915T) running rooted Android 5.1.1 just encountered the infamous green screen seen. The first time, the green screen disappeared after entering sleep mode and waking up, then about 5 minutes later, the green screen stayed, even after a full reboot (even the Samsung bootup animation, download mode, and TWRP were tinted, so I think we can rule out software issue). The phone was still navigable and usable, just with a serious heavy green tint, curiously, the phone would change between the heavy green tint and a grey tint, and the tint would stay on the upper 30% of the phone and turn grey as it entered sleep mode, almost as if the phone was trying to correct the display or something was barely making contact inside the phone.

Then the green tint got more intense, I could make out the basic background, the fingerprint scanner let me past the lockscreen, and the S-Pen sounds would still play when the S-Pen was removed, inserted, and when the screen was touched. Additionally, my PC does not pick up the Note Edge, yes I have the Windows drivers installed, USB debugging enabled, and MTP + ADB enabled via the secret menu in the dialer. Also OTG is down, my mouse and keyboard are receiving power, but no longer recognized.

Now, after another reboot, the phone is stuck in a bootloop, with the Samsung and T-Mobile sounds playing over and over again, there is a green tint when the Samsung logo should be playing, but a dark screen (as in, AMOLED off) when the T-Mobile animation should be playing.

The phone can't even properly boot into download or recovery mode anymore.

The phone wasn't exposed to heat or pressure, it was just charging off an ASUS power brick and a LG microUSB cable (and was relatively cool, not hot).

The phone was bought second hand, KNOX is tripped, and well past the warranty period.

So my questions for everyone here:

-Any idea what the problem is? GPU failure? Bad solder? Short circuit? Screen failure?

-Any hope? I heard someone else was able to get rid of the green screen after freezing the phone, but at the same time, I don't want to risk condensation inside the phone if I don't have to, and if it was melted solder from some sort of charging issue, heating the phone would probably be a better solution.

While I do have backup phones and and a backup of all my files in case something like this happened, I'm going to miss the curved edge and the S-Pen, and I don't want to take the phone to a 3rd party repair shop, considering you can buy an used functional Note Edge for less than the price of a replacement display, besides, the new Note 7 looks nice.

Anything that hasn't been mentioned above would be helpful... Thanks

UPDATE:

Now the screen doesn't turn on anymore, it flashes green when turned on, but remains dead. The T-Mobile sound still plays, and the motor rumbles for a second, but the fingerprint scanner and S-Pen rumbles and sounds are no longer responsive notification light pulses between white and blue.

Attempting to boot into download or recovery mode yields 2 seconds of green screen, then the T-Mobile boot up sound.

UPDATE 2:

Phone boots properly now judging by the fingerprint scanner responding and S-Pen sound, touch screen also seems to be functional based on S-pen cancel sound, but screen is now completely black, is it safe to assume a screen failure/damage?
