Hi! the problem you have mentioned is retrace line, it is cause by a loose solder on the crt board, a leaky capacitor. because you have mentioned that it only stays on for a few seconds.

TV TURNS ON,LINES ACROSS SCREEN THEN TURNS OFF BY ITSELF


sounds like a vertical problem, usually you'll see one white line across the screen, but one I worked on would come on and the bottom half of the picture was gone and there were lines across the top of the screen.

If you know how to solder & can find the vertical output chip then you could try resoldering the pins. If this doesn't fix it then it needs new parts.

This Problem is usually caused by Leaky Capacitors in Vertical deflection circuit.
If you are handy with electronics,
Get a can of FREEZE Aerosol.
Open the Back Cover.
Put a mirror in front of TV.
Locate the Vertical Circuit.
Turn the TV on.
Spray FREEZE on top of individual Capacitor to see if it corrects the problem.
If it does, Replace that Capacitor.
