1.2.6 Element substitution method

When some elements cannot be judged good or bad, substitution method may de adopted directly.

1.2.7 Comparison method

A same good PC board is usually used to test the correct voltage and waveform. Compared these

data with those tested through fault PC board, the cause of troubles may be found.

Through the above maintenance method, theoretical knowledge and maintenance experience, all

difficulties and troubles will be readily solved.

1.3 Required device for maintenance

100MHE)

TV set

SMD rework station

Multimeter

Soldering iron
