1. Observational method

As the name suggests, it is to use the eyes to visually check whether the components are burned, damaged, deformed, discolored, cracked and whether the CRT filament is lit after the current is turned on, etc., these problems are often the fault or closely related to the fault, find these problems, you can quickly judge the problem, so as to repair the industrial touch screen.

2. Percussion method.

This is also one of the most effective ways to overhaul industrial touch screens, especially for faults caused by poor contact. The method is to use the insulator to gently tap and press the parts that may have problems under the condition of powering on or without power, and it is easier to find faults such as virtual welding and poor contact.

3. Current measurement method

Measuring current is one of the basic methods for repairing industrial touch screens. It is mainly used to measure the load current and operating current of transistors and integrated circuit blocks, so as to detect whether the load of integrated circuits, transistors and their power supply is normal, etc. As long as the measured load current of the transistor or integrated circuit is normal, it can be concluded that the circuit is operating normally. On the other hand, if the current changes greatly compared to the normal value, it means that there is a problem with the circuit, and the right medicine can be prescribed and a focused inspection can be carried out.

4. Replacement method

The replacement method is a practical and quick way to overhaul it. When you are not sure which component you have, you can replace it first. If the fault of the good component is eliminated, it proves that the original component has a problem. This is especially true for components that are inconvenient to measure.
