    Hi,
    An old home cinema we had in our company..
    I cleaned that monthly by Petrol or sometimes the Oil..
    Once the last time I cleaned that by Gasoil[Diesel]!
    Then after connection to the socket it's ICs were been sooo hot above 200˚cg!!

    Why that was been that!!??

    I was detested brand of Samsung versus the Japanese brands..
    But since that time that i was been introduced with that type of Home-Cinema that I saw it was working hardly with these many clays/dusts I believed in that!
    And it's amplifier was Texas Semiconductor
    Bravo..

    Question:
    Is there any conductor within the Diesel?
    Or Has diesel gone inside of the elements?


    I have any source for my sayings,
    Also either have any source for deny your sayings,
    Or agree with your sources,
    Or pause about your sources while find an other opposing source versus that,
    Or will be shutting up.

    Hydrocarbon solvents do not conduct electricity.

    I expect you've dissolved some of the insulation and so the thing is shorting somewhere.

    During the 7 years I cleaned that how?
    Every month i disassembled it's boards including PowerSupply, Amplifier,
    DVD & Radio.. and put them into a tank of Oil for 2 days..
    Then cleaned them by the pressured air then reassembled them..
    Sometimes by petrol..
    But once that was by the diesel was been that damaging!!
    And it shows the logo of Samsung and Loading..
    But the USB reader doesn't work,
    AUX too.
    Radio too.
    And the DVD player was been damaged at the past, bcz of its eye,
    And only one of the cheaps of the board of Radio has been damaged and hot so much!
    I guess it was the IC of multiplexes or DAC/ADC..
    I withdrew working on that
