Here.

old enough.he can use 680ufF 25v rate allot on ebay

I don't know the answer, but I'm sure the 10v ones will be fine. Pretty sure you can go up in voltage. And caps are super easy to solder anyway.

I am struggling to find the 680ufF6.3v on AliExpress, well ones that ship by AliExpress. 680uF 10v don't seem as tricky to find. Sellers in the UK want about 6 times the price for 1!

[newgen2005]

I can solder, most certainly not an expert but I think I should be able to do this. I will order ESR Tester off AliExpress as I think they will be cheaper than Amazon.

I am no rush to get this fixed, will be nice to get it up and running and hopefully I will be able to repair some other faulty units.

Ahh I thought you meant you were ready to tear it apart today. If you don't mind waiting then it's best to get something like this

You know how to solder yes? To change them you'll need to do that

And yes you can get capacitor kits.. but generally a pack of 10 caps for your specific ones you need is probably 1-2$ so buying a kit may not have the exact ones you need, but maybe they do. Generally when I looked at the kit they didn't provide what I needed so just bought individually

[newgen2005]

Again thanks for the info. Just one more question, can you get capacitor kits on somewhere like AliExpress that cover the ranges I need? I have another Panasonic that will need new caps, thought a kit would be a cheaper way of going about it!

[EazyBone]

Generally you can take a resistor and put them onto each leg of the capacitor. I don't know which rating, maybe a 10k resistor, Google can help, and it will slowly drain it. Or just wait several hours to a day and check with your multimeter for any voltage left. If you can't check with multimeter because the connector on bottom side, you can just wait a day or 2 should be discharged

As for removing it. No clue. Does look interesting the connectors.

[newgen2005]

Thank you. How can I make sure there is no voltage left on the board before I start removing it? Am I correct in thinking you can get an electric shock when working on PSU's?

Also the board seems to be connected to the board on the VCR side, bridged with brittle looking connectors! How do I separate the boards?

This one also looks imploded, at least from the pic

[EazyBone]

Yup, several that are rounded up as lotas pointed out. Any that are rounded need replacing and then any that are imploded also. But as lotas said best to check with esr meter. Probably fixable

[lotas]

These are the ones, but it’s better to check all the others using an ESR meter.

[newgen2005]

Are these any good?

[EazyBone]

Take a clearer picture of those blue caps, they look collapsed or swollen from the picture, but the picture may just be off focus

I picked up a Panasonic DMR-ES30V (UK). When I first plugged in there was nothing, appeared completely dead, I then turned it on and off a couple of times at the mains supply and it came on. It accepts a cassette but then spits it out straight away, the DVD drive functions sometimes but then the unit turns off with nothing on the display. I took the back off and noticed the fan does not spin. The display for the DVD side does seem a little dim when it is working.

I have looked on google and people say it is most likely a capacitor/s.

Just looking for some advice on which capacitors might need replacing. I am new to this so please excuse my ignorance

Thanks.
