    From thermal image camera to freeze spray to injecting voltage with lab psu and then all back to basic touching ��
    Just cook it! It's already broken.

      Re: checking for shorts

      Finding shorts on boards it's all about reading and following schematics and voltage. There's no magic trick for it.
      More important that finding a short is understanding the failure, following the voltage to where the failure occurs, doesn't really matter if it's a short, open circuit or a faulty component.

      Electronics knowledge is the most important to understand and finding the failure.

        thanks for input. ive been staring into one schematic in particular and i am starting to understand more and more of it so its definitely sinking in.

        any good schematic tutorials something that might help me a bit?
        Thanks

              PS5 EDM-033 UART 80810001 Beep 1 second Ligth
              by Egidio85
              Hi everyone, I have a ps5 EDM-033 that beeps, blue light for 1 second and turns off.

              reading the error codes via uart gives the following code:

              80810001 General power failure (periphery, GDDR6, APU, data line shorted)

              checking the card I didn't find any shorts, Boot sequence is quite right 325 mA dropping to 9 mA.

              Using the thermal camera I can see the SSD controller and South bridge getting warm.

              if I press the power button the RAM also heats up, the processor doesn't seem to. in fact if I go to measure I don't have +1v CORE output....

              Carrier HK50AA063 display controller common failure help
              by ctroxtell
              I've got a control display for a Carrier chiller that I'm trying to understand what the common failure with these boards are. This is the board in question https://www.supplyhouse.com/Carrier-...arquee-Display all of them seem to develop a failure with the up and down arrow buttons on the right side of the display, the esc and enter keys I've never seen fail. Once these boards are plugged in they run 24/7, you used to have to press extremely hard with the end of the blunt screwdriver and you could still get the arrows to work but now it has completely stopped working. The button...

              Vizio E55-F1 dark backlight zones. LED failure or Dimming Zone Driver?
              by howardc64
              Problem

              Fixing a dimming zone TV with LEDs not lighting up. Dimming zone circuit introduces added variable to diagnose LED and/or Dimming Zone Driver board? Some 1/2 rows of LEDs appears to be out in active dimming zone off AND some brightness flickering with active dimming zone high while playing changing video



              Model & Board Pics



              Conflicting Spec

              Vizio indicate this TV has 10 dimming zones. However, LED strips and Zoned light driver connector suggest 12

              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...
