      Two things come to mind. Vs maybe a little high or yes logic firmware on control board. I've also seen a missed adjusted Y main Yramp cause this.
      Did I leave the soldering iron on?

          Denon AVR-X4000 – Fast red blinking after 2nd relay
          by SevenOFF
          Hi everyone,

          I’m working on a Denon AVR-X4000 that goes into protection mode (fast red blinking LED) shortly after the second relay click.

          According to the service manual, a fast red blinking LED indicates a DC detection (DC_DET) or ASO (abnormal current) fault, meaning the unit is detecting a potentially dangerous condition on the power amp or power supply side.

          Here’s what I’ve done so far:
          • Fully opened and cleaned the unit (a lot of dust inside)
          • Removed and visually inspected the AMP board → nothing visibly damaged or burned
          • Testing is done with
          ...

          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...

          Biomass Boiler not driving cleaner motor relay. ENERTRES BIOMASA BI-650
          by edugimeno
          Hi everyone!
          I have this board that suddenly stopped supplying power to an output that drives an interchanger cleaner motor.
          I checked while the board was in place with all wires attached and there's no AC voltage on the corresponding plug X5
          This X5 is driven by fuse F8 (tested OK) which comes from the second orange relay
          To make sure there are no charcoaled contacts inside the relay, I got a 24VDC power supply and got it ready to manually power up the coil side of these relays.
          I respected the polarity, positive to cathode of protecting diode
          So provided all...

          Mitsubishi CNC switching power supply board dead / relay board bad diode failure
          by sam_sam_sam
          I was working on this CNC machine today found no keyboard functioning no control relay powering on
          The screen powered on and was giving an operation error but the manual was not very clear about what the error exactly was but with a little bit of troubleshooting and finding out that the control relays not powering on and no keyboard functions we narrowed down to this one switching power supply which of course does not have any indicator LED light they are on the keyboard interface/relay controller board

          Found shorted diodes on main controller relays there are 3 of them that...

          Garage door RX unit (Cardin S38C) does not short relay to send opening signal
          by CoinCoin88
          Hello everyone,

          I'm turning to the Badcaps community to help me troubleshoot the radio Rx card from my (old) garage door opener. While I could just ditch that card and replace the whole system, I first would like to understand "why" it suddenly stopped working, because that's just how I am wired...!

          Some basics: the receiver works on a 30.875 Mhz frequency. Yes, I'm aware this is not in use anymore in a looot of places. It does not use any rolling code, it's just a regular dip-switch code that you have to set up on both the receiver and transmitter. The receiver...
