Am I Selling Schematic Diagrams?

By on February 19, 2009


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 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.

    Hi Jestine,

    I have purchased your ebook on Repairing LCD Monitors. Very good, but does not cover modern 22ins Widescreen models.

    Do you have any diagrams for the LG W2234S? or any helpful stock faults?

    Many thanks,

    Hi Ian,

    Thanks for your support on my ebook. As for the schematic, i notice that many newer models are quite hard to get the schematic-most probably technicians did not upload it into free website like By the way may i know what is the problem with the Monitor? Kind to share?

    HI David,

    Peel off the bottom cover first with a flat metal plate (not a screw driver). Once done then proceed to open the side cover. In some LCD Monitors, you must first remove the base/stand before opening up the cover.
