    I just want to add one thing so you understand how lucky you where.
    You lifted the PSU and first contacted ground THEN the live heatsink.

    If it would have been the other way around, (live heatsink first) then the current would have gone through your body looking for a ground.
    So if your feet where grounded it would go that way.
    If your other hand was holding the chassis of the PSU it would have gone through your arms.
    Just so you understand how serious this is...

      When I was in the U.S. Army AIT Signal school for FEERC the fist thing the insructors taught us was to always remove rings, watches and dogtags from ourself before repairing electronics and also to keep one hand at all times in your pocket.

          It should be obvious but just in case - there is heart on both these paths. If the voltage induced was AC than you have problem. If it is just DC potential it is not so serious, you would get some electrolysis in your vains and you would drop it. But with AC you get muscle spasm so you cannot let go of the thing you hold.

            And with good reason.

              Start with checking the fuse and input rectifier, the heatsinks are grounded to rectified ground which may still be on different potential than the earth ground. Otherwise the silicon in FSP PSUs is for many years in fully insulated TO-220F packages so no other silicon should be affected.

              The 100uF cap on the auxiliary rail from stand-by supply is gone too. If you want I have D8 caps just for these units as they are still quite common and known to go bad because of bad custom crapacitors so I can supply you.
              Thank you for offering to help me, but as I said up there, I gave it to the repair store.

              Yes, they are... but the question is, does your house have proper grounding? Because if not, then the case can become live without tripping anything. Modern electric codes in most countries now require a safety ground on each outlet. However, there are still plenty of old houses in many parts of the world that don't have grounded outlets, including here in the US. As a matter of fact, I lived in one like that while in college. The thing is, I had hardwood floors everywhere and the house was sitting a few feet from the ground, so I could touch live wires all day and not get shocked . Just keep away from sinks, pipes, faucets, coaxial cables, and other (possibly) grounded objects.
              The fuse in my house burned when this happened, so that would mean the grounding is alright?

              Thanks, I will for sure think about this next few nights before I go to sleep, I was holding the cap with both of my arms.

                get an extension cable, cut it in half and put an earth-leakage breaker inline.

                  Just for the record, the PSU housing is not only for protection against accidental touching of live wires but also to direct the airflow properly so it goes over the heat sinks and other hot components. Removing the sheet metal changes the airflow pattern and can overheat things.

                    LG OLED77G2PUA Not Powering On After Storm
                    by Alain Renteria
                    Got it for free on marketplace because it stopped working after a storm.

                    When I began troubleshooting the power supply, I fried 2 fuses and a mosfet by shorting 2 pins on accident, but I've replaced those components.

                    The tv had a soundbar connected, which was also killed by the storm. On the tv side I found a transistor shorted on the hdmi 2 (arc) and a lot of capacitors shorted on the main board.

                    Disconnecting and reconnecting the psu to main board cable, while still being connected to 120 V AC, would wake things up, such as a red light from the optical...

                    TCL Roku 55S403TCAA dead after storm
                    by bobbintb
                    I have a TCL Roku 55S403TCAA. It quit working after a storm. Other electronics quit working as well so I am pretty sure the storm had something to do with it. Anyway, I took a look at it, no obvious damage, blown components, scorch marks, etc. I am looking at the power board first, 40-L141H4-PWG1CG. I've repaired bad caps and blown components but nothing more extensive beyond that. I am trying to troubleshoot it, but I can't even find the fuse on this board. There are markings on the PCB saying "replace fuse as marking" however. I attached a photo of the board. I am also testing the...

                    by disorder
                    hello guys,

                    i need help to repair a edm-033 ps2
                    history : as always hdmi port and usb ports destroyed after unplugged
                    after change them, ps5 dead too : 1 beep, no blue light. after inspection 1.8v power was shorted, and because of dead panasonic chip. after remove it : no short anymore
                    so i changed it
                    now i have got 5v stby,, 3.3v stby, 3.3v power, 1.8v power and no short on them
                    but the ps5 is dead again : 1 beep, near 10 seconds with power lines and then off, no blue light ...

                    i don't see any projection of liquid metal on pcb.
                    ...

                    Curious - clock going ahead
                    by televizora
                    I've encountered curious and strange issue with HP Probook 8470p - the clock is constantly going ahead without any reason at all.
                    If I try to synchronize it, everything is fine, but after hour or two I notice that the clock is again 9-12 minutes ahead.
                    That's extremely weird. Logically, I checked the time zone and DST - everything is fine there.
                    That's only if the laptop was put in hibernation and then turned on again. If it was turned off and then on - everything is fine.
                    Any suggestions?

                    iMac A2438, destroyed capacitor and coil.
                    by LaPCon_IT
                    Hi people.
                    iMac A2438, board 820-02009-06. Some insect has killed itself destroying capacitor and coil next to it. No chance for buying donor board, so I'm asking you for help about values of destroyed components.
