It is not difficult to find that composed of elements such as Q802 standby voltage regulator control circuit, the important role that don't look at it in like normal work of the TV. So, first of all the false load maintenance standby voltage control circuit is normal is a very important step, as long as the guarantee standby voltage control circuit is normal, ShiJia load when the main output voltage 100 v, you can rest assured bold to meet pass circuit switched on maintenance, even damage of main pulse width control circuit doesn't work, will not spread out the area of failure. This is the machine designed two sets of interconnected and independent determined by the pulse width control circuit, we can make full use of this characteristic, the manifestation of grasp fault, flexible use of resistance, voltage, short circuit fault, open circuit fault, and troubleshoot quickly.vJ2service manual download site
