I like to fix things rather than just throw them out. Often the hardest part of fixing something is working out how to get the back off to take a look inside. Luckily, the Internet is a great resource for this.
Occasionally, I find no information about how to get the back off something and I have to resort to the old fashioned technique of a big hammer and chisel. Once I have worked out how to get the back off, I like to return the favour to all those who share the knowledge so here is how to open a Technics PX30 Piano and a Roberts Sports DAB radio without having to use a big hammer.
