D link switch won't turn on

[Shubham_41]

Hey guys today there was a power cut off at our area before that my DLINK DES-1016D was working fine. It is connected to a router and then an Android TV and A Pi is connected to a switch after the power was back on the switch does not want to start. I removed the plug and inserted into another plug it turned on and in a fraction of second it turned off. I removed all the LAN cables and tried plugging the power cord in another switch but still the same thing happens I opened the switch and checked the PCB but nothings Burnt I tried unplugging and plugging back some cables inside it. But the same thing happens I've tried 9 wall sockets (power plugs) but it turns on and goes back off. Please help me.

It's either fried or something is shorting it out. Could be the power brick - which is also the power supply. Could also be a blown capacitor. Either way it's dead - sorry. Look into using a UPS in the future.

Likely something wrong with the power supply. It likely partially runs but as the equipment start to take full power it fails.

Not likely that you are going to be able to troubleshoot a hardware design there is no documentation for, even if you do most things are surface mount parts and you need special tools to replace.

In some ways this is where a external power block is nice....even though those fail much more often than internal power.

I suspect your only option is to buy a new switch. I run all my equipment on UPS so the only time stuff goes off is when the power is off longer than the UPS can hold.

Actually it was happening before 1-2 months but when I plug in and out and in the power cord and also the lan cables, it was getting on again

It really doesn't matter the days of fixing electronic equipment are long gone. If it had multiple internal boards you could replace one but nobody sells them. Look at how many extremely expensive tv end up in the trash because you can't get parts to fix them. Not like the old days where there were tv and radio shops all over that could fix things.

So what should I do now?? Should I check with other power cord?

 

[bill001g]

I suppose you could but I have yet to see a bad power cord. I have boxes of them since they are standard and are the same as they were 20 years ago.

I've asked my brother to give his power cord for few minutes I'll see if something happens and will notify you thank you @ bill001g

It turned back on yesterday night after changing the power cord but today when I woke up it was off and when I tried to power it back on it goes back off.

So, it was obviously showing signs of dying. It's done my friend, maybe it's a blown capacitor (like I said in my initial response). Can't be sure unless you're willing to open it up and inspect it. Also, as Bill has said, it won't be worth bringing anywhere for repair. Here is a YouTube video of someone else replacing a capacitor on the same model switch.

NOW we get the truth.

So what should I do now

People is been telling you IS DEAD, you just don't to hear it.


Actually if you just want a challenge, how about replacing the internal power supply? Do you know your volts to your amps? Own an multimeter? No guarantee of course, but you sound like a very optimistic person.
