If I understand your post correctly, your a referring to retrace lines. Try turning down the screen voltage at the flyback. A make and model number of the TV would help for further diagnosis. You might also want to check out www.FreeFlatScreens.com/?r=10948674 for an opportunity to earn a free replacement for this set with a little effort on your part

I replace fbt by new one but this lines appear too.
my tv is samsung ct-5366 .

You still need to turn the screen voltage down. It is the bottom knob on the flyback.

I turn it down but any seconds after this lines appear and picture go to
bad colour and flicking and in flicking go to better pic and negative pic
I guess that crt is faulted.
Thank you melw for reply.
