My module was working fine for months but few days ago a vertical line appeared on the screen. Photo: https://photos.app.goo.gl/wxG1877kWAopf2Fv6
Tried to contact the manufacturer/seller via ebay without any luck. Product seems and feels cheap (the case) but I would expect this sort of device to work more than six months. I certainly would pay some extra for better case (and no dead lines on the screen).
Seems like hw issue but any suggestions?
