Panasonic DMR-ES30V power issues

[newgen2005]

Yes, higher voltage (10, 16, 25v,...) is possible, but lower voltage is not possible.

And most importantly, observe the polarity of the capacitor (-, +) when replacing with new ones.

Thank you for confirming, just ordered some from AliExpress, and an ESR meter. I have removed 2 of the suspect capacitors. Sorry for the dumb question but the hole where the leg is soldered to the board has small section of brown is that because I have removed too much of the solder? I was worried I may have damaged the board!

I don't see, and I can't say anything, what you did there.

Spray alcohol and wipe with a q tip. Probably will go away

Using flux right?

[newgen2005]

Not used flux as I didn't have any.

[EazyBone]

That's a big mistake. You must use flux. You burned that pretty good. As for fixable I don't know since I've never done that. Maybe someone else can tell ya
dont do anything else until you get it.

[newgen2005]

Yes, I think I've messed up here. Hopefully I can do can do something with it.

this nothings to do just solder new one in place..
BUT good to see the circuit.. don't use any caps as yours first questioned on 680uf 10V will work,,,so don't use over rate more than 10V and don't use any over or less 680uf

[lotas]

It's not a big deal, you just overheated the pads and they peeled off, you need to add flux or use rosin, old boards used getinax (modern ones made of PCB) and they don't like overheating, clean them with a toothbrush moistened with isopropyl.

[newgen2005]

Thank you, I will use flux next time. I have some on order.

The 2 caps I removed were 680uF 6.3v and 680uF 10v. I have ordered 680uF 10v as a replacement for the 6.3v as I couldn't see any that were shipped by AliExpress.

Cleaned but it looks a right mess! Lesson learnt! Hopefully I haven't destroyed the board!

Carefully clean (remove the mask (varnish coating)) with the sharp tip of a scalpel, wipe with an ear stick moistened with alcohol and tin the area with solder...

Appreciate your help, thank you. How about the other part of the board? (the one that looks the worst) Do I need to remove the mask?

Are the brown sections without the solder just the none conductive part of the board?, I think the pad was under the solder so nothing conductive left?

I need to understand how the board works.

[lotas]

Well, the same thing here, clean and tin...

I have replaced both capacitors, the machine powers up and plays videos but the dvd player audio isn't working. When I dub from VHS to DVD no audio can be heard from the VHS, the disc does record the sound though as I finalized the disc and played in another player. Any ideas?

[Diah]

recording / copy Data are blind work.. playing / review are coding matter.. if the code not supported you can nothings do with it

[newgen2005]

I should of mentioned audio on the DVD doesn't work at all, you can hear like a static noise.
