Answers :

Different faults here.
\015\012First fault is no power, it is bad capacitors on the power board.
\015\012
\015\012Second & third faults are the inverters. (power but no image visible, but feint if you shine a light into the screen)
\015\012Check the 4 transistors on the main power board for shorts.
\015\012
\015\012If you are unsure what that means, then take it to your local TV technician, he should be able to solve it fairly cheaply.

\015\012Hope that helps.
