Question about Acer X203H bd Monitor
Those voltages does not sound right, it should have 5v for the logic board and 16~20v for the inverter board for this 20" screen size, but you are getting the white screen which means that the backlight is working, so your measurement may be wrong. The white screen means that the T-CON board is not feeding either the 5v or 12v (depend on the screen makes and model) that will be the first palce to check, the logic board supply this voltage through a switched transistor to turn the T-CON board on or off (off during standby mode).
