If you buy a new millet TV, if the remote control is not easy to use, you can't call it every day. The TV that cost a lot to buy but lost on a small remote control? Today Xiaobian teaches everyone a trick to get rid of the remote control and it is always a sudden failure or always prompting the problem of low battery.
1, in the case of ensuring that the remote control battery is fully charged. Please check the battery compartment of the remote control.
2. If, as shown in the figure, the positive contact of the remote control is a flexible metal wire, the area of ​​contact with the battery is too small and unstable. Causes the battery to be in loose contact with the remote control and cannot supply power normally.
3. When the battery is installed, the positive electrode of the battery cannot be tightly attached to the back cover after the back cover is closed. During use, the battery shake causes poor contact.
4, if the above problem occurs, then just as shown in the figure, in the battery positive pad a thick piece of paper or add a sponge and the like, you can perfect solution.
Fast Recovery Diode (FRD) is a semiconductor diode with good switching characteristics and short reverse recovery time. It is mainly used in switching power supplies, PWM pulse width modulators, inverters and other electronic circuits as high-frequency rectifier diodes. Free-wheeling or damper diodes are used. The internal structure of the fast recovery diode is different from that of an ordinary PN junction diode. It belongs to a PIN junction diode, that is, a base region I is added between the P-type silicon material and the N-type silicon material to form a PIN silicon wafer. Since the base area is thin and the reverse recovery charge is small, the fast recovery diode has a short reverse recovery time, a low forward voltage drop, and a high reverse breakdown voltage (withstanding voltage).
