You would need the service manual in order to change the picture tube properly as there are dangerous voltages stored inside the tube also the tube would have to be set up properly as well. You can get the service manual for your model at the following link. They will email it too you right after purchase. Heres the link.

The lines you saw, i;m sure they are the ones called retrace lines but know the failure could be located on the red CRT board. Most likely the video amplifier is defective and not necessarily the CRT.
What is the model number of your TV?

YOu have convergence issues. Ok first question. IN your setup menu do you have the convergence option/ if you DO not then it can be a specail fusable link. fl231 if you do. next question do the picture bow in at the middle. if you do then it possibly a convergence power supply issue. next if you go into setup convergence does the crosshairs adjust up or down left to right on both blue and red. I if so then theres is a chance that it can be a convergence adjusment or a amplifer problem AS always THIS SET CAN GENERATE LEATHAL 380 VOLTS EVEN WITH SET UPLUGED SO BE CAREFULL.
