My working Kanga unfortunately has loose hinges - the screen stays up fine but it wobbles and any pressure can send it slamming shut. The plastics are all good (save the usual missing port doors) so I think the hinges/clutches themselves may be worn out. I’ve sourced a set of NOS replacement clutches, but I’m not sure how to tackle the replacement. I’ve got the service manual but I’m hoping someone who has actually done it can give me some tips on how to do it. Any advice is much appreciated.
