创维TV—2198型彩电是创维集团近年来才推出的新一代多制式彩电,其电源电路市电适用范围在110～260V,特别适合农村和市电不稳定的地区使用。该电源采用并联型开关电源,其电源的开/待机是由微处理器MN152810经继电器RLY401控制+110V的通断来实现的,当电视处于待机状态时,电源电路仍然处于工作状态,长时间的连续工作,就导致了电源出现故障的机率增大了,又由于其待机方式和其他电源
Skyworth TV-2198 TV is a new generation of multi-standard color TV launched by Skyworth Group in recent years. Its power supply circuit has a range of 110 ~ 260V, which is especially suitable for use in unstable rural areas and mains. The power supply using parallel switching power supply, the power on / standby by the microprocessor MN152810 relay RLY401 control + 110V off to achieve, when the TV is in standby mode, the power supply circuit is still in working condition, a long time Continuous work, resulting in a higher probability of power failure, but also because of its standby mode and other power
