Line faults & possible causes to LCD & Plasma screen are given with illustrations. You can get an idea about the fault to an extent. Faults to all LCD & Plasma screen are similar, irrespective of its brand and screen size.

Start with a replacement Tcon board

Problem #1) Convergence

it's an lcd filter fault it's betwine lamp and screen before mirror, seems like u will need to replace it but it hard to say without look at it.

46" Samsung LCD, screen is distorted and has wavy lines across the screen.

about half value of tv,

Can you describe in a little more detail what the symptoms are? Are the streaks thin lines or are they large thick swashes of Blue? Is yur video still visible? Sounds like it may be the blue convergence amps or the resistor tied into the amps. is there anyway you can post a picture of your screen distortion?

Disconnect the monitor from the computer and turn the monitor on
it will display a diagnostic colorbar are the lines still there.
if not they are likely a cable or video card.
if they are still there have a tech evaluate the monitor.

This indicates a convergence problem..convergence power supply probally.. however ive seen 2 other cuicits cause this ..

This is due to vertical section failure. Change the vertical supply rectifier diode and supply filters. Then check zener diode leakage in pumpup circuit section. Also check any electrolytic capacitors leakage in vertical section. If it is old model tv change vertical height, vertical lenearity presets also. I hope given details useful to you.
