    Welcome to Android Central! Does this persist after a reboot, or in Safe Mode? https://support.t-mobile.com/docs/DOC-28736

    Test it in Safe Mode, which temporarily disables all 3rd party apps you installed. If it goes away in Safe Mode, then you know the problem is due to one of those apps.

    (I'm not sure what you mean by testing it in Recovery Mode. Do you mean you did a cache partition wipe?)

    If this started after you rooted and installed a custom ROM, it most likely has to do with that.

    no problem was exist before root and custom rom . i think my tablet problem because of lcd cable

    It could be the cable, but since you say the problem wasn't present before you installed the custom ROM, then logically, the ROM becomes more suspicious, doesn't it?
