How To Test Tv Main Board With Multimeter. You can check out the two photos below: This is easily done using a multimeter set to a voltage range.
You can search “how to test a motherboard with a multimeter” in google to look for detailed steps. Hold it in place for a few seconds and wait for a continuity reading. Turn the knob on your multimeter to “capacitance” mode.
If The Multimeter Indicates That There Is No Supply Voltage Then There Can Be A Number Of Possibilities To Investigate:
Touch the multimeter probes to the circuit board test points if you're measuring voltage. The lead plug is colored red for easy identification. If you're measuring the resistance of resistors, connect one probe to each end of the resistor.
In Polarization, Connect The Positive Terminal To A Red Multimeter Probe And The Negative Terminal To A Black Probe.
The red probe goes to the test point and the black probe goes to ground or common. Connect and turn on the power to your circuit board again and measure the voltages on the inputs and outputs of each of the components on the board. Use your voltmeter (see tips) to check the voltage level of all of components' input and output pins.
Finally, Set The Multimeter Effectively In Its Continuity Test.
This position generally has a sign with several small parallel lines and a diode icon. This lg led 24 inch tv came in for repair with the complaint of no power. If not, the fuse is blown.

Connect the red probe to the positive side of your component, which is where the current is coming from. Multimeter voltage test helpclick here for tv parts: Connect the multimeter probe to the capacitor terminals.
Plug The Red Probe Into The Vωma Port.
Place the multimeter knob to the continuity test position. Turn the knob on your multimeter to “capacitance” mode. You may be interested in how to test motherboard without cpu.
