    But an esr meter is an excellent investment. You can find on ebay at very low price.
    I search ESR meter tester:

        Re: Bad PSU shutting down my PC

        i have a same issue.
        My pc is shutting down suddenly.it's the PSU issue. That's obvious.i 've tested.

        There is no blown caps in it.

        but i desolder biggest couple of caps.

        They must be 820 mF.
        one is 720mF other 650 mF.

        are they reason of shutting?

            After 4 days away home, I turned on my PC yesterday and after several hours running it didn't turn off. I didn't use a hair dryer on PSU, I only turned it on and no problems until now.
            Maybe after 4 days of resting my PSU fixed itself
            Should I still look for bad caps on it?

            Edit: It did shut down a few minutes after I post here.

                Yeah I would still look for bad caps. It sounds like that's what the issue is. Teapo has a high likelihood of failing without showing symptoms.

                    If the PC is reseting during load, and heating the PSU temporarily fixes the issue, then capacitors are the most probable culprit. Just replace the capacitors on the secondary side with equvalent long life ones with at least 105°C rating. Manufacturer put a bunch of wires over them blocking the airflow and overheating them, causing them to prematurely fail.

                            Not necessarily during load, it happens usually a few minutes after boot. I will test the capacitors on the secondary side soon. Unfortunately I don't have a capacimeter, but I will try to borrow one.

                            Looking the pictures I would say it is the same PSU.

                                Hair dryer in water

                                Hello everyone!
                                I dropped a hair dryer in the water after using it. I pulled it out fast but it was still hot, plugged in the mains and switched off. Still in warranty but the shop I bought it is in another country. The local repair shops asked 50-60 eur for repair. The dryer cost 60 so I was thinking maybe there is smthng I could do to fix it my self. I took it apart but I reached the point that I cant understand what the problem might be. I dont have electronics knowledge. Just some basic electrical.

                                There are 3 leds that are blinking when is plugged in but it does...

                                Whirlpool dryer control board
                                by Eaglecrest
                                I have a Whirlpool dryer that runs for a while then stops with a blinking timer screen. The dryer can't be reset by hitting any input and if you pull the plug and plug it back in it also won't respond. Light is on in the drum when you open the door, but no other sign of life. If I leave it unplugged for a period of time, which is multiple days, it runs again. May be able to get a load done, but now seems to be less than full load before it errors out.

                                Since unplugging will get it to work, I am assuming that there is an error condition that is causing the onboard processor to shut...

                                by BigPete
                                I picked up a Panasonic NH-P70G2, though it would apply to the NH-P80G2, NH-P70G1 and NH-P80G1 models as well, as maybe some other models. This one was coming up with a H86 error. After lots of testing and googling it was an error with one of the thermistors in the condenser area.
                                The attached French service manuals is incorrect, TH11 is gray and is a 95k thermistor and TH12 is black and is a 35k thermistor.
                                In my case TH12 was bad. I was able to get a 35k thermistor on AliExpress. It's 6mm in diameter.
                                Unfortunately the whole machine has to come apart to fix it.

                                Yoga 530-14ARR NM-B781 Ryzen 3 2200 – overheating and shutting down under load
                                by Maniackk
                                Hi,

                                I’ve got a stubborn patient here. The laptop powers on and works, all components like the screen, keyboard, touchpad, etc. are functional. The issue is that it heats up very quickly under load (within a few minutes up to 95°C) and then shuts down shortly after. Subsequent attempts to turn it back on right after a “hot shutdown” result in it shutting off within a few seconds. Interestingly, if I enter the BIOS, it can stay there for 2 days without shutting down (most likely due to low CPU load and low temperatures).

                                The cooling system has been cleaned, thermal...

                                Bosch Nexxt 500 dryer blinking start button - no start fix
                                by CapLeaker
                                My Bosch NEXXT 500 dryer quit today, press start nothing happens and the start button just keeps blinking. Not cool. Reset the dryer, same thing.
                                Even so the buttons feel good, my problem was the start button smd tactile switch on the PCB. Cleaned the switch with alcohol followed with Deoxit and the sucker runs like a champ again.
                                I like these easy evening fixes!
