I’ve accidentally drop off my oneplus 5T then the screen imagen stop working but the touch response still works. I’ve never opened it. This would be something like disconnected display or maybe the display is broken and need replacement? Everything else is working except for the screen image.
@javieresp from your description it sounds like a bad screen. I’d go ahead and replace it. While you open your phone you will have to check all the cable connection anyway so the work will be identical. OnePlus 5T AMOLED Screen & Digitizer Replacement
