    I have tested my JV33 main board.

    Found TP8 was below specs.

    Does anyone know exactly what the components are called that are soldered on the main board areas TP1-TP8?

    They are extremely small components, and even under high magnification I can not find any markings.

    ANYONE? know what these are called, and where I might get replacement parts?

    Thanks and have a HAPPY THANKSGIVING.

    they appear to be a row of small capacitors. tp just means test point (the place where you make a measurement). neither the test point or the capacitor is the defective part that needs to be replaced.

    what is the voltage at tp8? what is it supposed to be?
    do you have a schematic diagram?

    Andy:
    According to the test procedures outlined from Mimaki, these "capacitors"? as you refer to them do NOT carry voltage. They are to fall into a very narrow range of OHMs. 17ohms to 18ohms. no more no less OR they should be problematic.

    I have not been able to locate a specific schematic. THAT would be very helpful.

    Any other ideas?

    my mistake

    in surface mount components, it is hard t tell a resistor from a capacitor.

    there are a number of places to purchase this sort of thing. digikey, newark electronics and many others.
