An ebay seller shipped me this broken tablet by mistake, and so I got my money back, but there are a decent amount of these seemingly in perfect shape but with screen issues (this tablet was clearly a return that had never been used or setup, so I don't think any physical damage occurred, also is a kids model so large bumpers on cover that isn't in picture) Is this a loose lvds cable or anything repairable beyond replacing the screen which would come with its own integrated tcon which is maybe where the problem would be?

The power on screens just exhibit the sideways smear, once...
