Onkyo TX-SR607 – No Front Panel Display

Onkyo Receiver TX-SR607 faulty

Repairing an Onkyo TX-SR607 amplifier / receiver where the front panel display had stopped working.

Everything else appeared to be working fine and it wasn’t stuck in the common fail safe standby state.

Onkyo Receiver TX-SR607 faulty

These units have a ‘pure audio’ mode where the display is switched off by the CPU, so it needed to be established if there was an actual fault or if the microprocessor in the receiver had just switched it off.

A factory reset was carried out to reset any miss configuration of the unit.

The fault was tracked down to an open circuit resistor effecting the power supply to the front panel VFD display. I have uploaded a video to YouTube showing what the fault was and how to track it down.
