Lines on tv screen then go away. Normal? or not?

When I turn my tv on the first time i see lines, but they go away. the model number is va19lhdtv10t.

ANSWERS:

@toasterclan possibly coming from the video input source. Your TV may try to scan first to check the video source. Change the input source to HDMI, component or any other one available on your TV. It will help if you let us know what model your TV is.
