The best way of doing this is to strictly follow the procedure in the service manual.
A simple way that might work is to set contrast and brightness to minimum, so that the picture is completely black, turn up the screen voltage until a weak raster with retrace lines can be seen and then somewhat back so that the raster disappears. |
thanks for the reply, unfortunately, I'm not a service technician, so I think I'll leave it to a TV engineer |
