The wiring loom between the power supply and main boards - try resoldering the sockets at both ends - a
known problem. If the red standby LED is flashing, replace the power supply. I believe the main IC (IC100) on the main board is a problem in these as well. Also check the 1Meg resistors on the inverter.
