I have one of these monitors and it had several capacitors blown in the power supply circuit. Replacing them all repaired my set.
Re-search in google, tells me this is a common problem, and when the caps go they sometimes take out the F200 fuse on the back of the circuit card as well as the power mosfets for the invertor. |

| If the caps and supply are fine....check the voltage at the power on button. It should be around 3.3 volts. Goes to gnd when pressed. If the open switch voltage is way below this, check the 3.3 volt regulator on the input board...should be 3.3 volts when the unit is plugged in. If not, change it. |
