    Pioneer VSX-1020 won't start /relay click /

    Hi. Yesterday receiver ''stuck/freeze'' on ''POWER ON''. Today no display, no blink, only main relay click. All compination enter+power button etc.... doesmt work.
    Amp section is perfect.
    On IC581 all correct ( i have input 5V/OUTPUT 3.3V)
    On D582 /cathode/ i have 2.7v
    C333/C506/C552/C606 are good, correct voltages.

    I don't have osciloscope to check crystals on processor. May be receiver won't boot firmware...
    Can you tell me how continou.

    Service manual is too big (32mb) to upload here, here is a link

      Pioneer VSX-44 receiver HDMI dropouts
      by RatherLoopy
      I have an older Pioneer receiver (VSX-44) that's been dropping the HDMI output (black screen) for a few seconds every few minutes. Setup is HTPC -> Pioneer DVD HCMI in -> Pioneer HDMI out -> Samsung TV HDMI in, all with cheap HDMI cables that have never caused trouble before..

      I initially found a lot of play in the receiver's HDMI inputs and output so I kind of squeezed them back into shape and they're making a tighter connection, but the problem persists.

      And also, often, the HDMI will drop out in exactly the same way (black screen) just as my central air...

      Pioneer VSX-1123 Receiver - weird voltage problem
      by pulper111
      Hello. My receiver "seems" to be working fine. It functions as it should. the receiver is the Pioneer vsx-1123. However, while doing some work in the house, I noticed that my HDMI cable from the receiver was registering as "hot" using my fluke non-contact voltage tester.

      I've done some troubleshooting to try to narrow down the problem, and all wires (speaker/hdmi/subwoofer) coming from the receiver, whether it's powered on or stand-by, register as "hot". none of my other receivers are experiencing this issue, so it doesn't seem to be an issue with...

      Pioneer amplifier A-205 Relay not clicking after a mistake i made
      by GraphicMan
      Hello guys
      Because the unit is old (but only occasionally used) the loudness button causes some noise due to bad contact,
      sprays did not work, so i decided to solder the pins that it connects on the pcb at the on (loudness on) position
      i did that and it worked fine, i know from the bottom of my heart that the switch connects 2 pins and also d/c other 2 pins
      on every position it have (6 pin switch), so i was curious what would happen if i clicked the switch off while the pins are soldered at on (so basiclly on and off at the same time), when i did so the sound is gone, nothing...

      9V relay temperature 40C
      by jm1234
      Hi, I'm seeing one 9V relay having temperature 40C on its 9V (primary) side. Does that seem right? I switched 2 relays on that board and the temperature was the same (on the same position), so I'm sure it's not a faulty relay. I measured voltage on that relay and it was 9.5V DC, so that looks good. I don't see any other relay on that board having that kind of temperature and they have 9V on them too.
      I thought maybe the transistor that is switching this relay keeps switching on/off, so I also checked for AC and there was almost none: 0.3V using mV range. No steady frequency was shown, but...
