GBDamage goods We purchased one smart board,it was delivered damaged, we received very little assistance with the issue. Someone eventually returned our calls and it was replaced with another damaged board. We had to get a third smart board and so far everything has been fine. We had to pay for three installations and two removals, which was extremely expensive and the company was not willing to compensate us for any of the expense. We are looking to purchase another smart board but we will not be making the purchase with this company.

CNHow to identify the components in the circuit 1. Online power-on test Mainly based on its model or working state to determine the voltage across the pin, such as diodes and rectifier bridges have a tube voltage drop, and the triode should judge the emitter junction voltage or collector voltage according to its working state. 2, offline measurement in the case of power failure, remove the components, measure the unidirectional conduction characteristics of the diode and rectifier bridge, and measure the quality of the triode with the basic amplifier circuit of the triode.
