Lcd problem or hardware problem?

[AliGolkar]

My LCD was broken, and i took it to a sony repair store and they changed the LCD, Afterwards, my phone stucks several times a day like the picture i attached and then it restarts and again this happens and so on, specially when it gets hot, i took it to them and they changed the lcd again, but the problem didn't resolve. Have you seen such a problem, what is the problem

Thanks
