Finding Burnt Components

By on September 4, 2012

If you have read my September 2012 repair newletter you would know that I have taken resistor as a case study. I have emails telling me that one could use the resistor substitution box or a high value potentiometer to locate the burnt resisitor value. Thanks for their sharing. There is no doubt you can use the resistor substitution box or even the potentiometer method but what I want to emphazise is that the article that I have shown to you is not limited only to finding burnt resistor. You can use the method to locate some other burnt components like capacitor, diode, zener diode, transistor and etc. If you have any comment on the article please provide a feedback-thanks.

    Hi Jestine
    Thanks for the tip on finding burnt resistor value i will try that cause i have a mecer tw222 lcd screen with that problem but i will have to replace the fet and power ic first and check for other components that might be faulty.I will also appreciate it if anyone is reading this reply im looking for a schematic of this lcd monitor.
    Thank you

    Good Day Sir.Jesting,
    I ask, how do i find a part number into a broken ic?i have seen mark printed into a pcb ic831s,it's a lcd monitor samsung b1930n,but i search in web there is no info for that ic and am trying to go in our nearest electronics store they said we dont have that kind of ic! or do you have a data sheet to replaced same parts number for ic831s? i hope you help me to found a solution to my problem. Thanks a lot....:)

      HI Gremloyd,

      You may need a schematic diagram to find the part number of the broken ic. Without the schematic it is hard to tell unless you can find the similar unit for comparison.
