Re: VSX-D704S

Have the speakers disconnected and turn on unit. If it still shuts down due to thermal protection the amplifier IC pack is damaged. Amplifier IC is tied to one side of the power supply by design. The left channel is probably shorted at the MOSFET on the pack. Nothing you can do but have it serviced. This is a common PIONEER failure.

I have a pioneer vsx-d704s reciever and when it is at a very low to 0 volume i get a low level scratching only on the left side. im not sure if it goes away when i turn it up or not but i dont think so

The volume knob is dirty. Behind the face of receiver the "pot", (as they are called) needs sprayed with contact cleaner. I use CRC QD contact cleaner. If the volume is a slider your can use the straw type devise for pin point spraying in the slider slot with receiver off and unplugged. After spraying work the slider back and forth to distribute the cleaner inside. If you have to remove the cover for a rotary "pot"spray while working the dial. Hope that helps..

My pioneer VSX-D704S won't turn on. Only The standby light turns on.


Your unit being stuck in standby mode is an indication that its having a power problem. Remove its plug from the wall and fix it back into the wall, then turn it on again. If its still stuck in safe mode, then the power supply board in the unit is the cause of the problem.

The power supply board might be defective and maybe that's why the unit won't power up. Its receiving power but it cannot transfer the current to the necessary part of the unit because a capacitor, diode, etc may have been faulty. Until these bad components are replaced, the unit might not come on.

To actually find out what's wrong, you need to disassemble the unit with a screw driver and check what's wrong. You will be needing a meter in order to test the components on the power board, once you detect any bad component, you can make necessary replacement at any electronics accessories store withing our vicinity. This is the only way by which you can detect the problem.

Of course, testing the power board with a meter will require someone that has the ability. So it you can't, then you might be needing the help of a repairman or you can call a friend that has the ability to help you out.

I wish you the best of luck.
