I can't seem to get accurate color, and I've tried a bunch of different custom color and contrast options... what should I do? (There is a sort of sepia tint to the screen)

Try adjusting the Screen voltage. Easiest method I know of: remove rear cover, locate the FBT (has a large red wire running from it that attaches to the back of the tube). You will see 2 or 3 adjustment knobs on it the should be labeled if you look close (screen is normally on the bottom). Turn the TV to a black screen (often an empty input works well). Slowly adjust the screen voltage knob (small screwdriver required) Clockwise, until you see some beam trace lines on the screen. Now, begin slowly turning it Counter Clockwise until the lines are gone and the screen just turns black again. Press the menu button and use the on screen menu and the top knob(s) on the FBT to fine tune the focus. Leave the cover off for the moment and see if your color is better. Repeat the adjustment if needed. If this does not help your situation, you may have something else going on... let me know.

Black line problems

Some components in the vertical deflection amp have been going out of spec with age.

The set may no longer be worth to spend money to service it because of its age. However, if you wanted to invest the money, the set is serviceable. Considering its age, the CRT may be soft, and there are many other older components that can soon fail.

I would be considering a new set.

White line horizontially through middle of picture

A repair like this is in the vertical drive/output section of the TV set. It could be a simple capacitor causeing this problem or a combination of the capacitor and the output IC. A repair like this should not exceed 120 to 150 US. Is it worth that to you? How much can you replace it for? Good Luck PS please dont forget to rate this thread.

Screen split with black bar through center, top of picture shows in bottom

It sounds as you desribe, the vertical output IC and or the b+ feed capacitor off the Hi voltage transformer feeding the vert. IC its required voltage. Not a really hard job to replace, but not for a handi person to do. This should be left to the professional, as there are no user serviceable parts inside this set and with the HI voltage and the safety issues its best to call somesone to assist you with this repair. Good Luck
