I have a problem with my monitor. When I open my computer the monitor works properly but after 30 seconds it suddenly turns into blank/black. What happen to my screen? How come it remains blank even if my CPU is still processing and working?

Hi,

You can clean the Flyback cable connected with CRT inside your monitor with Thiner (available in the market). If it is not changed in this way you may have to change the Flyback of your monitor. Besides Flyback there may be problem with the High Voltage circuit of the monitor. Try to check the entire Condenser on it carefully.

You can also check Resistors, Diodes and Transistors carefully. Change them with a good one if there is any problem found with them. If you are not skilled enough to do the above mentioned task by yourself then contact a good technician.       

I hope you understand it.

Thanks
