The present invention is applicable to, for example, an active matrix type image display device using an organic EL device, and a short circuit location between wiring patterns is able to be repaired. In a scanning line WSL or a signal line DTL, a bypass wiring pattern BP for bypassing a...
Let's discuss some general tips regarding the possible faults with a swatter mosquito bat, and ways to quickly investigate and repair them. It would be interesting to know that 90% of the time the faults associated with a damaged mosquito swatter bat isdue to shorted mesh net, or an exhaus...
2, the controller internal power supply damage Controller internal power supply damage, generally have the following possibilities: the controller internal circuit short circuit; peripheral control components short circuit; external lead short circuit. 3, the controller is intermittent work The controller i...
PCB troubleshooting and repair involves visual and electrical inspections using various tools such as a multimeter, LCR, and, oscilloscope.
As a result of this development, wires may cross, resulting in short circuits which destroys the circuit board; the water’s presence will speed up the reaction time. Via microscopic examination (often with the scan electron microscope) of themicrosectionand directly on its surface layer, CAF ...
indicating that there is trouble somewhere in the circuit. A blown fuse or tripped circuit breaker usually means there are too many appliances plugged in to that circuit or some malfunctioning device, like an appliance with an internal short, is connected to the circuit. Locate and eliminate the...
The sting of witnessingair only blows through defrost ventsin the car can also be triggered by a blown fuse, the part protects the entire ventilation system from dangerous sudden overvoltages (electrical surges). When this unpleasant phenomenon occurs due to a short circuit, electricity will not ...
This is probably due to one of two causes: Too much current is being drawn on the circuit. This could be a defective chip that the circuit is driving or a short somewhere on the output of the circuit. If the board is being powered by a power supply, look at the current being drawn...
The following through the online measurement method to explain how to repair the circuit board: Step 1: Power on the board In this step need to pay attention to is that some of the circuit board power is not a single, may need 5V, but also need plus or minus 12V, 24V, etc., do ...
How to Reset a Breaker Finding the Cause of a Short Circuit Why Has Your Breaker Tripped? Types of Circuit Breakers Before we dive into a step-by-step how-to process, we should probably identify the different types of circuit breakers. Each type is designed to serve specific functions ...
