Check power supply to system
If not power check and repair power supply unit
Power supply is normal, go to output of block B to check for signal.
If there is signal, check output of block C
If there is no output from block C then block C is faulty
If there is output from block C then block D is faulty
If there is no output from block B then check output from block A
If block A has output then block B is faulty
If block A has no output then check input signal to block A
If there is input signal to block A then this block faulty otherwise it means nno input signal.

Instruction cycle, machine cycle and T state

An instruction cycle consists of fetch and execute phase. Every fetch and execute is called an machine cycle. The time for the machine cycle during the fetch phase is always the same for every instruction while the time for the execute cycle is depended on the events, each cycle actually needs a few clock pulse or sometime we call it T stat. some microprocessor may have 5 T in one machine fetch cycle and during the execute cycle may have 6T the clock frequency and the number of T required will determine how fast an instruction can be executed. A higher clock frequency and a lower number of T will definite run faster.
