请问这两句英文应该怎样说?

我想看看这台机器的屏幕有没有死点(坏点) I'd like to check whether there is any broken blot on the machine's (or maybe computer's) (LCD) screen. 能不能帮我贴这张屏幕保护贴上去,因为我自己不会贴,会有气泡 Could you please help me put up the screen protection cover? I couldn't put it up properly, but could only brought about bubbles under it.
