Various components of folding machine tests are not unusual, and the bottom plate connected with the power ^^^ output voltage reaches 5V, the test switch machine parts has reached 3.3V, with a multimeter, power indicator light, please heroes under the guidance of brother ~ ~ thank you!The display is Acer V193W, about a year

You check the 5V and 12V voltage of the power supply terminal with multimeter. If the normal voltage can be controlled in the switch signal probe connected to port at the same time, press the power switch, the control voltage of the port should be about 5V with the switch. If this voltage is not shown, the drive panel is out of order. If the voltage cannot be maintained, the high voltage board or the load is faulty.
