If I remember rightly - there is a resistor that controls HT current that goes high in value that causes the screen to blank. This can be confirmed (only by qualified persons!) by tweaking th A1 control on the neck of the tube and the picture will return. However if the resistor on the main board is not replaced the fault will eventually return plus this can cause further damage if left. |
