Without seeing the lines I can't be sure what your set has wrong, but here are a some possibilities:

If the lines are lines are confined to the top inch or two of the screen and the picture looks otherwise normal, the trouble is bad capacitors in the vertical output circuit. Fixable by replacing the bad parts.

If diagonal lines are across the entire face of the picture tube and the picture looks washed out, the trouble is often a bad capacitor on the 200-volt line to the picture tube. This may be on the main circuit board near the horizontal output transformer, or on the small circuit board plugged onto the end of the picture tube. Again, replacing the bad capacitor can fix this.

If your TV is actually an RCA, someone may have bumped a rear-panel adjustment. On the back of the TV near the bottom right are two small knobs. RCA left these adjustments exposed inside of putting them inside the set like other manufacturers. These sometimes get bumped if someone was behind the set cleaning, or if a pet got back there and hit them with a tail. The top knob adjusts focus, and the bottom knob adjusts something called G2 or screen voltage. If this gets turned up too high it can cause the faded picture and diagonal white lines. Turn the adjustment down until a black screen looks black instead of gray.

A bad picture tube or horizontal output transformer can also cause lines through the picture. If this is the case with your set, it's time for a new TV. The transformer is relatively inexpensive but labor costs aren't, and the repair bill may exceed $200. If the tube is bad, there's no point even considering repair. The tube cost alone exceeds the cost of new TV.

Hopefully your lines are easy and cheap to fix. Good luck, and thanks for using Fixya!

Hi

where the line is coming out? from left to right of your screen or bottom to top?

Thanks!

it can be a picture tube problem. moreover, check if your tv is dusty inside it . clear it with blower and try again.


regards,

Sounds like dropped pixels.  My first guess is the computer has been dropped on its corner, with the pixel dropout radiating diagonally from the corner.
My saint bernard sat on my g3 lombard, and I have vertical pixel dropout because of it, from the top of the screen to the bottom.
And no, it is not normal for a macbook to have lines across the screen.

Hi.

Just read your list of problems The first fault (Diagonal lines & picture collapse from left & right) Sounded like either A poor connection or dry solder joint either on scan coils or scan coil plug / socket on main pcb.
If this were the case the engineer that called out should have spotted this & sorted it very easily. But you say it is still the same so what did he do ?
Did he give you a reciept with break down of what he did ? If yes please post it here for me to go over.

The sound problem you describe has thrown me a little so could you please post your tv model number on this page so I can see if this is a stock fault.

The static shocks you are getting is relatively normal & not a problem unless you are getting them off of speaker grilles or even tv casing if it is silver in colour.
I am UK based & have access to samsung technical but I will need your tv model number.

These are called retrace lines they occur because of the blanking pulse not turning off the electron guns in the picture tube during the retrace period. Since this is occuring with the red gun there may be a proble with the video circuitry connected to the red electron gun of the picture tube. This would include the red amp and the red driver transistors. You will need a schematic and a multimeter to properly test these items.
