Am I Selling Schematic Diagrams?
For your information, i do not sell any kind of schematic diagrams. I used to get lots of email asked me whether am i selling schematic diagrams or not. Normally i would direct them to eserviceinfo dot com to look out for any free schematic diagrams on any electronic equipment. However some websites do sell schematic diagrams for example http://www.9manuals.com/ sell only the laptop and notebook schematic diagrams for various brands like the ACER, Hp, Samsung, NEC and etc.
Sometimes in electronic repair we need schematic diagram to look out for the exact part number/value of components. The components could have been missing, burnt or no value/marking on its body. With the schematic diagram you can also analyse how the particular circuit work and understand more about the different section that formed the complete electronic circuit of the electronic equipment.
