No need to apologise INH but it may help more if you can find someone who could advise or mentor you on a one to one basis. Online communication has its drawbacks and being shown how to proceed in person can be much more successful than trying to describe things in print or even by video. There is a shortage of instruction venues nationally but [in London especially] you may be able to find one of these new volunteer repair workshops/hobby groups or a radio/electronics club that would be able to offer some direct help. Those Clubs are always looking for new members on a technical and social level.
In the past, many people would do this as the first step and receive a lot of help and encouragement. Combining that with the Forum may be a good way forward for you. At the moment you are restricted to just asking questions here which may not be so good in itself. I hope this helps
