How to disconnect links on PCB?

[Blagard]

The image below is my panasonic DMR-E75V main power board. You can even see two suspect capacitors that are swollen.

To replace them I need to extract the board but I don't know how to disconnect the two links (to other boards) on the right edge. They are in the form of wire bridges.

Any one know?

They look like they should lift off of the right hand board to me.

Indeed they do! - I have just come back to post that I made that discovery. I found I could unplug the right side just with my finger nail!

Thank you for the reply

Make sure you fit decent caps. Panasonic, Nippon Chemicon, Rubycon, etc.

Observe precautions for static electricity.

Those capacitors are bulging because they are not low ESR types.
Read this page about replacement capacitors:

If you buy the wrong type you'll end up doing the job again in the future.

I've had very bad results myself with Rubicon.

Perhaps that's because the company is called Rubycon, not Rubicon?

I had already ordered the capacitors titles as below.

1500uf 16v 105c RUBYCON ZL series LOW ESR Long Life

There are the also the same physical size as existing. The only thing I am sure about is that the swollen ones should not look like that! - From what I have read, they seem to be a likely culprit for the loss of power.

Actually, they are. Elna RJF series. The specs sheet appears to be numbers lifted directly from Rubycon's ZL series (as Blagard has purchased as replacements), which makes them questionable, to put it mildly.

Those are appropriate replacements. Those caps are definitely the root cause, whether they've taken any other components out.. well, you'll find out when you replace them.

Capacitors arrived this morning. Fitted and my old VCR/DVD combo is up and running again! - FYI the machine is around 15 years old so I think the old capacitors may have died of natural causes.
