The end of one recorder era

My Panasonic DMR EX75 HDD/DVD recorder has given up on the Freeview signal again. Checking the usual overheating 680 microfarad capacitor, I didn't find obvious signs of failure. It wasn't blowing it's top as the previous failures had done, for example -

But given the inexpert deposit of excess solder I left the last time it's possible the failure was internal or further under the board. I decided to attempt to replace the capacitor again anyway. Unfortunately two attempts to replace it failed, largely due to my incompetent soldering skills, I suspect.

Tinning the soldering iron tip proved unusually problematic this time. So I cleaned it with wire wool before the second attempt (and after it had cooled completely to room temperature). Note that you need to be really careful with this not to strip the iron surface bare or you'll find yourself in need of a new soldering iron.

As I said before, though, if you're thinking of tackling something like this, especially if you are an infrequent actor in such an arena, be sure to snip the legs of the failed capacitor quite high up on the first pass, so that you have a solid base to crimp the legs of the new capacitor to before soldering. My original failure to do this meant successive replacements over the years have been increasingly difficult to crimp/graft and solder.

I seem now to have reached the point of no return, at least as far as my rusty engineering repair skills are concerned.

I blame middle aged eye-sight and the need for reading glasses for close up work too. It's probably just as well I don't have to build flight simulation rigs any more, though I'm pretty sure I could still do the mathematics, the modelling, the design and the testing the parts of aircraft to destruction bit - operating the rigs and running the tests was never as tricky as constructing them.

Well the saga of the Panasonic DMR EX75 HDD/DVD recorder draws to a close. In any case, the machine won't now pick up the Freeview signal and though I can play what was recorded up to losing the signal, I can't record anything else. The old box of electronics is going to have to be retired. It's taken in

• the perils of online purchasing
• the monumental irritating stupidity of DRM
• the dealings with an approved Panasonic repair shop, J.F. Associates
• the stamina required to deal with zombie rule bound "customer service" centres of large companies
• Panasonic's centre will, once the requisite quantities of precisely the correct type of metaphorical bureaucratic blood are donated, and are pushed in the right direction by an independent Panasonic repair centre, replace faulty parts on their machines
• the freedom to tinker (or not) with electronic boxes of tricks like HDD/DVD recorders
• did I mention the monumentally irritating stupidity of DRM
• the power and the economy of the freedom to tinker
• the value of the internet and all those helpful people connected to it, willing to help out those in need of tinkering tips and tricks
• the easy access to cheap electronic components the replacement of which can negate the need to replace an expensive box of electronic tricks unnecessarily
• and not to forget the incredibly monumentally irritating stupidity of DRM

I hope the next recorder finding it's way into the B2fxxx household has a long but less eventful existence.
