Bought a used G90 receiver through ebay and it does not turn on. Since there is no warranty and I'm a fairly handy tech, I opened it up to have a look. When power is connected, the green led on the power board lights up so there is AC power coming in. Cycling the power switch does nothing, display does not light up nor do any of the indicator leds. There are no obvious sights like burn marks, liquid damage mechanical force etc. All wires, connectors and connections seem to be intact. Are there any other quick checks I can make internally to try to rule out simple problems before sending it in for service?
