Vertical lines I have very thin, evenly spaced, vertical white lines (like pinstripes) across the entire screen, all the time.

This is screen problem .
You may be loosing somewhere on the screen of your screen, if not
If there is no losing then you change the screen

To clarify, are the 3 black lines horizontal (left to right across entire width of screen)? or are the 3 black lines vertical (top to bottom across entire height of screen)?

Horizontal lines are almost always the result of a failed panel, and no board replacement will fix the issue.

Vertical lines such as you have described (only 3) are probably also a bad panel. If the black lines were evenly spaced in a repeating pattern, it could be a mainboard or TCONN board.

Has this panel been cracked? or perhaps cleaned recently with too much water or cleaning solvent that has gotten the screen wet?

You may have to sell the TV for parts.

Line, faults & possible causes to both Plasma display & LCD screen are given with illustrations. You can get an idea about the fault to an extent.

Tara, if the ink levels are ok, try clean and allignment functions from the tool menu. Use CLEAN UNUSED PAPER.

reset the settings to factory reset. the resolution is not syncing up.

that is due to lcd filter units , try to align, precision work

Look for bad capacitors in the vertical deflection amp, and in the pin amp sections. This is common on most of these types of TV sets.

The caps tend to go high in ESR with age. It is best to use an ESR meter to find the bad caps. It will be a lot faster than workign out waveforms with a scope.

Is the set blurry with pinkish color and white lines?

sound like the screen control on the flyback is set just a little too high. the flyback has the red wire attached to the tube. the flyback has 2 small adjustable controls. if you look close enough 1 is marked focus & on is screen. turn the screen slightly to the left & look at your picture. the screen is like a master brightness & if it's up too high you will see what is called retrace lines. good luck.

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
