I have an horizontal white line in a black screen. i have an idea that could be the vertical modul but have no electrical schema to identify the capacitors or other componenets

You can usually find the bad caps with an ESR meter. There are only 3 or 4 capacitors in that circuit. Also, if you have completely lost vertical deflection you might want to replace the vertical ic. I always make it a habit to change the caps regardless. They are pretty cheap.

High pitch buzzing.

Hi there
Let's make ur problem a bit clear. "white lines" how? where?
meaning retrace lines with full raster or a single vertical line?
buzzing sound? without even turning the power switch of the TV to "ON" or when u just plug the power cord?
I'll check for schema, mean while can u tell me where the resistor leads to? is it a fusible resistor? if so , to which area the resistor suppliers power?

Image flat line

Vertical sweep failure.
It will be an I.C. with a part number that probably starts with an LA_ _ _ _ and be on a heat sink in the vicinity of the connector going up to the yoke. Try replacing that. But first, check all the electrolytic caps around it for testing dry (sorry - takes a special meter to do it in circuit) or just replace them. May have lost power to the I.C. as well. Look the I.C. up in the free NTE crossreference at get a diagram of its pinout to find what pins the power and outputs are on.
Hope ya fix it!
