In my opinion, unless you are experienced in that kind of thing (soldering etc), or are prepared to gain those skills, you can't. If you do have the skills (or know someone who does), you should have a pretty good idea just from looking at the damage. You may be able to use a part salvaged from an old TV, or solder a short length of aerial cable in place of the broken socket and fit an in-line socket to that.How do I fit a new antenna in?
That is very bad - not only for the reason you have discovered, but also for cooling. The unit needs a free circulation of air, and there will have been a lot of dust ingress. While you have it opened up, give it a good clean as well. In future, do not site it where it will have to be moved on a routine basis (never a good idea for anything with cables, and if you must then disconnect the cables first).Hi our box sits on the floor under the sofa so gets moved regularly when hovering.
Yes, I think so. I am willing to do the job if you are prepared to ship it both ways.Probably easiest to add a length of coax cable and fitting
You really don't want to be relying on that. Please don't put it back under the sofa!a flexible coupling might have prevented the problem to start with.
Not so far, and the only way it would have helped in this instance is if a working input tuner module could be salvaged from a dead motherboard.Alternatively, did a parts store get set up?
