Hi,
today my RB450G suddenly stopped working, blue and green led are up, but no ethernet link any more. If I turn it off and on again, there is some activity on the green led, but no link either. There was also no beep when finished booting, so I guess there is nothing up?
I tried to connect via serial port, but I got no data here either, not 100% if the cable is the right one.
Any glue if there is a chance to have this fixed, or should I put it in the trash (for recycling of course).

I’ve had this happen on many routerboards. Open it up and see if any of the capacitors are buldging or leaking. If so, replace them and it’s as good as new!
I have a similar problem. It seems it happened last night after I’d gone. And now that I’m here I see just the LEDs are up. Shutting the power on and off, doesn’t work. No activity with Eth Ints. LEDs are not blinking, just on!
Is it the capacitor? Are you sure? cause it’s labeled and I don’t want to open it unless I’m sure.
PS: Nope. There is nothing wrong with the capacitors, not that I can see.
Thanks
One of the capacitors looks different to the others, we’ll give it a try and replace them. Yesterday they arrived, hopefully a friend of mine will replace them in the next days. Will post the result.

Yup. There are 3 capacitors in the board. One of them is bigger and the other two are alike. But it doesn’t look troubled.
Thanks
Sorry for the delay, the friend of mine replaced the capacitors and the board is working again. It doesn’t looked troubled to me either, but what do I know

Excelent post.
Sorry for take it but it is exactly the problem I have. I’ll try to change the capacitors this week.
Thank you.
Hello,
@Pive
Perhaps to late but should solid capacitors do the job for a longer time?
That exact topic of early-failure has been beat to death here… it ended up being something to do with counterfeit capacitors shipped worldwide that affected a lot of products, not just mikrotik.
Perhaps I was nor able to understand as well as you mean it, but what was false on giving the tip
to use solid caps instead of the normal ones?
I am also owning a RB450G and RB435G an I was also soldering
solid caps onto the boards, or better a friend of mine was doing it for me.
