Re: Can one faulty cap in parallel with working cap cause problems?

Transfer over the LAN did actually degrade over a few weeks. When it was working, I would get a transfer rate of about 3MB/s. It went down to about 200KB/s and stayed that way for about a week. It then went down to about 50KB/s. Now, a few weeks later, I am lucky if I can transfer a file a few kilobytes in size with success.

Re: Can one faulty cap in parallel with working cap cause problems?

I guess the only way to really find out is to remove the capacitor. I'm a bit scared to do it, though.

The device is a satellite receiver, the Dreambox DM600. The problem, I think, is the 220uF 16V capacitor....

Re: Can one faulty cap in parallel with working cap cause problems?

I will try to cut one of the legs of the capacitor.

What I've noticed since the degradation of the connection is that the LEDs on the port of the network switch that it is connected to constantly flicker even though there is no traffic. Is this a symptom of a faulty capacitor?

Re: Can one faulty cap in parallel with working cap cause problems?

Thanks for the replies.

The reason I'm asking is that I have a device that has a LAN connection which is not working properly. I've read online that replacing a capacitor may solve the problem. I don't have the equipment to desolder the capacitor so I thought by just holding the new capacitor onto the underside of the board I would be able to see if there was a difference. It did make a small difference, I was getting less timeouts, but still nowhere near as it should be.

If there is an electrolytic capacitor on a circuit board that is faulty, is it possible to place a working electrolytic capacitor (with the same specifications as the faulty one) in parallel by soldering it on the underside of the board and have the circuit brought back to normal operation, or will the faulty capacitor still cause problems?
