20 Most Recent Harman Kardon AVR 430 7.1 Channels Receiver Questions & Answers

Has the DVD settings been altered so that it's now putting out an analogue signal?

that receiver does not have HDMI, so it will not be able to reproduce the full spectrum of surround formats from a Blu-Ray or PS3. You can still hook it up via the other inputs at reduced resolution. As for the price, I'm in America, so I can't give you a fair estimate of it's value there.

In general, your PC's sound card (and its controlling software) will determine what it can connect to. Even the most basic PC would have stereo analog output via the typical green 1/8" connector or a headphone jack that easily adapts to RCA pair for REAL audio connection. Any Line Level input EXCEPT PHONO would accept the PC's output. The output level would be controlled by the sound card software and settings. More-advanced sound cards would have similar adaptable 5.1 or 7.1 (paired) analog outputs and / or digital audio outputs that conform to the s/pdif or Dolby Digital standards. A digital-capable receiver would accept 44.1 kHz for normal CD or DTS sources. Some diddling with the output sampling frequency might allow digital multichannel audio to be decoded by the receiver.

According to the Harman-Kardon AVR 630 User Manual, if the 8CH mode is not available, you can try unplugging the unit from the AC wall outlet and waiting for at least three minutes. After the pause, reconnect the AC power cord and check the unit's operation. If the system still malfunctions, a system reset may clear the problem. The 8CH may not be available according to the user manual. You need to contact Harman-Kardon customer support.

Normally when you remove a unit's case everything is fixed to the base and the back. You remove the screws in the board and lift it up. See if this video helps, which is also a capacitor removal. https://www.google.com/search?q=harman+kardon+avr3550+replace+caps ..
