This is most likely bad connections at the vertical IC. Look for a small flat IC with about 9 pins or so. It will be attached to a heat sink and will be marked LA7837 or something similar. Resolder the pins on this IC. Report back here if that does not resolve the problem.

White horizontal lines on top of screen


Replace all the electrolytic capacitors in the vertical output section circuit. There will be 5 or 6 of them. Replace the at one time. The fault you see is technically called " vertical retrace lies".

This is a sign of your LCD panel beginning to die. Sometime soon those lines won't fade away and will become permanent parts of your TV screen.

Considering the fact that your TV is approx 3-4 years old, this is normally the expected lifespan of a TV. Once the TV becomes unwatchable, your best bet would be to begin shopping for a new one.

This is not a DC power supply problem. You most likely have a fault in the Vertical deflection circuit of your TV. You will need to get a qualified technician to look at this.

Thin red horizontal lines across screen


replace the focus block or try to adjust the screen control on the focus block for red only. this will affect the white balance of the set so adjust it carefully. the focus block is located on the front inside the set. remove the speaker cover then the 4 screws on the front plate. the focus block is 3" x 2" black box with 6 adjustment posts three for focus and three for screen. adjust only the affected screen (R).

Heavy white lines accross the screen


Replace it, it is going bad. I could tell you what would cause this such as bad driver IC etc. but bottom line is its five years old, you got your moneys worth out of it so bite the bullet and get a new one.
