I need to replace the smoothing capacitors on the internal power supply of a Beomedia1. I gather that the internal power supply is fitted directly to the top of the power input socket on the motherboard and is held in place by a latch.

Can anyone tell me how to release the latch? Do I need to remove the motherboard for this, or can the lever for the latch be reached with the board in-situ? I can't see an easy way to reach it, and I can't tell which side it is on.

OK, I've solved it. The latch is on the side away from the hard disk and there's a hole drilled in the PSU PCB directly above the latch. The solution was to insert a fine (watchmakers) screwdriver through the hole, with the top of the screwdriver over the hard disk (so the bit went down the side of the catch away from the disk. Raise the screwdriver to the vertical, pressing the top of the catch towards the connector, and it unhooked.

Now I can get those capacitors changed!

When you start replacing capacitors, don't forget the ones in the external psu.

You"ll have to crack that one.

Still waiting for it to arrive - just thought I'd fix the internal PSU whilst I'm waiting!

Do you have any tips for opening the external PSU? A rock and a hard place do not seem very subtle.

Hi Mark,

i wouldN't try to open the external PSU. The parts of the case are glued together and the probability you break it are high. Just do yourself a favour and buy a new power brick at eBay or somewhere else ( possible this one or similiar  (It's not me offering this part)).

It makes you live easier.

Thank you. I did take a look at power bricks for sale in the UK a while ago, but the best prices were around £40 + delivery, so resurrection of the original brick seemed a better idea. However, prompted by your message I've looked again on ebay and found a whole load of them for sale at reasonable prices.

The parts are glued indeed. But with the right amount of force, you will end with only 2 parts :-)

Hitting it gently on a corner of the case makes it possible and more easy to open the rest of the case.

You only need to crack the glue, not the case itself.

 

It's a lot cheaper than buying a new one.
