I plug it in and the red standby light comes on as usual. When you hit the power button the standby light goes green for a second and you hear a click. After about a second you hear another click and the standby light goes red and starts blinking orange. I have tried the unplug and wait method. I have browsed the boards and see no blow compasiters or burn spots in the boards. Any thought on what the problem might be?

I have had some issues with high ESR readings in the capacitors in the scaler circuits in those units. Do you have an ESR meter to check the caps in circuit?
SOURCE: won't turn on. unplugged, waited, tried again,
make sure u cycle main power switch before u unplug then unplug wait 30 seconds and repeat one more time

(Green Power LED will go Green the Go Off) Brief rise then collapse of the Vs and Va voltages. This indicates a "Load" on the line. Pull the CN-64 connector feeding Vs/Va voltages to the X-SUS. Take an ohmage reading from the Va and Vs lines on each PWB. This means you have to read the Connector on the Power Supply and the pulled connector going to the X-SUS. See if there is a low value. Low value indicates a defective PWB. Normal reading should be infinity. (Using the diode mode on the DV/Voltmeter, there will be a brief charge time, then infinity.) In other words, it may appear as a low ohm reading, but should rise to infinity or open. (Also not, if there is a charge on the line, the meter may show a low. You must Pull the CN68 connector and take a reading again). The line should now be infinity when reading the Power supply pins for Va and Vs and when reading the connector going to the X-SUS PWB.)
If a Low is see on the connector, pull the CN32 Connector. (Bottom right hand plug on the Y-SUS PWB)
