the problem starts when the display turns violet sometimes in my CRT monitor and i figured it out , i just replace a new VGa cable and soldered it to the board and thing goes right but suddenly it wont display and LEd flashing. i have to remove it from the source then plug it in to have a display . And now i have a problem, im wondering what happen to my monitor because when i start my PC, my monitor's LED keeps flashing and no display but when i remove it from the source then plug it in i hear a 'tick' sound the way CRT monitors should be then it have display. every time i start my pc i keep doing those procedure...removing the monitor's voltage source then i plug it in to have a display...what should i do? what are the thing to be done to make it right?
