I considered doing that, but, judging by what I've read, even if it were repairable (which, theoretically, I strongly suspect it is), it looks as if that would be likely to cost at least as much as a replacement. However, I'm still thinking about what to do!Have you considered sending it to a repair company. May save you having to scrap your tester.
One pragmatic way of looking at this is that, over the period I've had my couple of 1562s to date, the cost of having them has worked out at only around £20 per year, which is not bad, even if I 'write off' the present one.
