D-Link DSL-2760U Power Supply

[Mazdo]

Hi all,

So not 24hrs after getting my Telkom line installed, my router power supply blew up on me, the router (warranty void) itself is fine from what I can see.

It's a 12v 1.5a power supply but apparently nobody in Cape Town stocks it, I have tried most well known PC or electrical stores. The only place I have yet to try is Zakspeed.

Does anyone know of a place they know that stocks it? Or a product (like a cheap 4port hub) with the same supply that I can use?

Thanks in advance,

Mazdo

Are you looking for a switching supply (90~240V) or a transformer? Just look at the unit which was supplied. The switching supplies are usually noisier which might not be ideal for a router.

Mantech apparently have a branch in CT (check the website).

It came with a switching supply so it looks like Mantech is my next stop on Monday.

Will let you know how it goes.

Thanks,

You can try getting one through D-Link.

Have you tried to open up the faulty supply? There is usually a screw located underneath the information sticker. You can just gently push a screwdriver through the label onto the screw once you can see the outline. You might be able to repair it by replacing several of the components which appear damaged.

Make sure that stock is available telephonically before driving there to avoid wasting your time. Take the old PSU along so that you can find something with a matching DC power plug. There are several different types of plugs available 2.1x5.5x9mm 2.5x5.5x11mm etc. The first dimension is the hole size (very important!), the second the barrel diameter and the third the barrel length. You may need to either replace the plug or make a short extension cable with the correct plug for the router on one side and an inline female to connect to the new PSU. Mantech should be able to supply most of the different types of DC plugs and sockets. It might be worthwhile to rather purchase an external hard drive 12V 2A supply which could be reused for storage purposes at a later stage if necessary ...

I opened the unit when I saw nothing wrong inside the router, unfortunatly it's not pretty.

A large portion of the underside of the PCB is burnt (I will get a pic up when I am back online), can't tell if it was a short circuit or surge so I will stick to a new unit for now.

I will keep D-Link inmind if Mantech have no stock, was hoping to avoid shipping and pick one up myself.

Got the new supply from Mantech and stopped off at Zakspeed to grab a connector block.

Cut the wire off the old supply and the head off the new supply, put them together and I'm back online! Cost me R70 total instead of a new router (R700+) that computer stores insisted was the only option.

Thanks again for your help Yotch!

@Mazdo: I'm not sure what kind of connector block you are using but if it's a standard black plastic terminal block with screws at the top it might be wise to glue it (epoxy) or attach it with cable ties onto a short piece (~3X length of block) of wooden icecream stick together with the cable at both ends to prevent the cable from moving around in the block and finally breaking off.

It might still be possible to repair that board depending on whether or not you can identify the faulty components. There are three blackened pins near the centre of the board which are presumably from a switching transistor. If you post a pic of the other side of the board together with the part no./code I'll see if there is any possibility of locating a relacement. Normally one would try to replace all of the damaged components around the blackened area depending on the cost.
