Those are really difficult to find replacements for, last I looked about £60+. Plus you're never sure if they've listed the replacement board correctly.

4.49 for 10 worth a shot
Discharge them before soldering. Or wait several hours after switching off. Test for any remaining charge using the multimeter. Might be an idea to open a thread in the technical discussion section, for the soldering experts.

It's best to get in and out asap, avoid too much heating of the components.

Grab some lead solder! Flows much better. 0.7mm worked great for those Cherry mouse switches.

3 caps tested show 14v 11v and 13v dc so no where near 35v

Wear a covid n95 mask while soldering. Horrible stuff, lead. Melts really fast and flows great though. Solder in a well ventilated area. Tin the tip of the iron, there are Youtube videos which show you how - just keep piling on solder, wiping with wire wool, plunging it into cheapo plumber's flux, melting on solder etc. over and over again until the iron's tip is completely covered with a lovely shiny silvery layer. Makes things so much easier. Also clean the tip with wire wool while soldering. Wait for things to cool down after each solder.

rang a few shops and all said no dont fix anything like this anymore, its renewable tech that you throw in the bin and buy a new one. :rolleyes:

Solder suckers remove solder really fast, with the right positioning...
