    12/24 volt compressor cooler box inverter capacitor failure

    This is my son’s cooler for his semi truck for his drinks the other day it started short cycling ( running for a second or two then shutting down ) and restarting four or five times then going into an error power cycle the controller then it would do the same thing again

    Found a 47uf@63 volts double the ESR value of a new one
    The 220uf@16 volts same as a new but 220uf@35 volt replacement capacitor

    The main filtering capacitor was not replaced because I did not have that was not too tall

    Where the 220uf capacitor is some type of switching power supply regulator of some type I have not had time to look it up but this picture is not clear enough for me to make out the part number completely

    I did not recognize the part number of something that I have used before

    So it works correctly now so let see how long this last

    One note the picture of the controller in the box is the new compressor and controller that I bought in case the compressor was the issue why it was short cycling I used the controller to see if it was a compressor failure or a inverter controller issue which it was that

    I found this YouTube video on how to test a inverter type compressor
    It also shows how to make a testing device to test the inverter type compressor

    Socket 940/939 Cooler bracket failure
    by ratdude747
    Found some missing pieces (thumbscrews) to one of my retired rigs, my dual Opteron X2 Socket 940 rig, went to move it to replace them, and made an unfortunate discovery:



    The freaking plastic heatsink bracket sheared off while sitting. Thank goodness that didn't happen when it was running!

    I removed the thermal compound before shooting that... it wasn't until after that I figured out why the cooler came loose, right as I was about to apply fresh

    I have some Dead/Disused socket 940 stuff floating around if I want the cheap way to...

    APSINT3636VR 3600W APS INT Series 36V DC 230V AC Inverter/Charger schematic
    by Gentian
    I have a tripp-lite aspint 3636vr inverter charger which blow some of mosfet transistors. I replaced them repaired also the driver circuit and tested but the mosfets burn again.

    It work very well as inverter and also as charger if I let the rear switch in auto mode (inverter) and charger only(charging) but in auto when I connect the feed line 220V AC first time it pass ok to line and start charging the batteries but when I remove the feed line it pass to inverter mode and if I do it again the second time when passing from charging to inverter the Main transformer start making a...

    Insignia NS-LCD19-09 (PS OK, Inverter problem?)
    by valvashon
    For some reason I'm just not going to let this 19" TV defeat me. I guess because I have a schematic to work from I feel like I'm oh so close.

    History- while adding a turn-on circuit I let a small screw roll under the power board. Worked through all of that circuitry, probably replacing a MOSFET and PWM controller that were not bad but I was following the service manual. Finally figured out that the power supply is in working order when the inverter section (for the backlights) is disconnected. When the +12 supply to the inverter is disconnected the +12 and +5 will come up...

    OLD Socket 478 custom bracket + NEW generic cooler
    by BleedCap
    I already posted this on vogons.
    Its a 3d printed custom bracket for socket 478.
    I used this AM4 bracket as a base design.
    Its to be use with cheap generic clip based cpu cooler.

    Reason for doing this is:
    - Its hard to get/find a good copper base cooler. Even if you find one, the price is ....
    - New generic cooler is cheaper and can use bigger fan (less noise)

    I tested the bracket with cheap chinese horizontal cooler + fan taken from CM hyper 212 evo.
    The processor that I was using is P4 2.4Ghz prescott....
