I have no idea for a service contact in your local, but some of the 1250 circuit boards(pcb's) can be removed as they have connector for easy removal. So those modules can be rebuilt without shipping the whole unit. Obviously having a complete unit on the bench is the best way but it is not the only way to accomplish a re-build of a 1250.
You should state exactly the operational condition of your unit and/or what work you would like performed so we have an ideq of what you are looking for. A complete re-build of a 1250 will get into the 100's of dollars for parts and labour.
