Interesting and Thinkable question of every repairer, and Answer is also cover the whole question thinking.
Actually, sometimes repairer having feel unsatisfactory condition and doubt about fault found . But, you have covered by an expert opinion.

thanks you

I check voltages at the ic, if there is no voltages there, I check the source of the volatage, one of the fly back transfomer..etc. if the fault is not power..I got to the power supply..and so on

This is what I am doing if I have no schematic but there are lots of components on the board. Normally if there's an IC, try to download the datasheet. There you can find the info on the component plus its function. The surrounding components on the IC are needed for its specific operation which sometimes you can find in the datasheet also (see application notes). Using the information on the datasheet, you will have an idea of the function of the circuit. You can even make a block diagram and try to focus only on the suspected area.

Testing all components take a lot of time, effort and money. For a repairer who has a quota everyday, time is gold.

Best regards and good luck!
