From your description the picture tube has gone, and usually it will crack where the filaments light up, once air gets in the vacuum seal is compromised causing particles to fly damaging the delicate phosphor where the picture is generated. The replacement of the picture tube will far exceed the cost of a new tv.
If the tv has nothing happening at all when you try and turn it back on including any noise, your power supply is broken. If it is still trying to turn on or does make noise, an internal component has come loose or been knocked off, most likely to your picture tube.
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? Regards Rifaa
