When I turn on the TV I have a small white line across the middle of the screen...After a bit of wait time the picture above it stretches and the line moves to the bottom. After a bit more wait time the white line begins to stretch upward and it takes quite awhile but the picture is fine. This entire process takes close to a hour.

Re: White Line =(
Based on your post, the TV unit is suffering with a Vertical collapse. Further, your description indicates that it could either be a capacitor problem or a cold solder. Though of course there are instances that it could be the vertical IC that may be defective.
This is a relatively easy repair and the part should not be expensive. If the problem is a cold solder, then simply reheating the solder joints with a soldering iron should correct the problem with no parts replacement. Even if you were to do a shotgun approach and simultaneously replace the IC and capacitor, again would not be that expensive.
However, the repairs do require that you be a bit familiar with electronic components and circuitry and the use of a soldering iron (with a desolderer). Should you not be comfortable dgoing this router, perhaps you can seek the assistance of a friend with soldering experience. otherwise, your best bet maybe to seek the services of a qualified professional.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

The vertical sweep output is absent. Check its vertical output section circuit for the fault. Check all the solder terminals of that section, and resolder them by applying a little more solder. Take special care to the solder terminals of the vertical output IC. If these do not help you, check and replace the vertical output IC.
The vertical output IC LA7847 is failing. It will likely fail permanately and you will have just the horizontal line. The set will require service. Just do not run the set very long in this state. That thin white line can likely burn into the crt phospher and will show all the time thus ruining the glass picture tube...
you have a shorted green CRT that is affecting the other crts the short is internat to the crt that leaves what is called retrace lines. if the set is more than three years old then replace all three guns.
im pretty sure you cant fix that you probably need to buy a new one.. i know that because my somputer has a white line that runs right down that middle, not all the time but sometimes. my father looked into fixing it and he found out that you have to buy a brand new screen or tower or something like that.
sounds like you have a vertical sweep problem. Where the fault lies cpuld be the vertical output IC the verticle b+ feed, could be the capacitors in the vertical circuit?? Your gonna need to troubleshoot thr vrtical circuit if your not a tech thin my advise is to take the set to a pro for sn est. Good Luck
