Hi everybody.
I have an ESPRIT ventilator. But now when connecting it to power source, main led is light. Turn it on, Alarm high led, Vent inop led, Safety valve led in the front of machine are light and sound beep appear, cooling fan not work, LCD screen becoming white, blower motor does not run, and led D5 on sensor PCB is light.
I have replaced another power supply board, analog PCB, digital PCB, CPU PCB and VGA controller PCB but the fault is the same.
If anyone has experience on this machine, please give me an advice.
Thanks.
