But did you know when they get to around 10yrs old or beyond they are likely to fail.
Having discussed various issues I had been having with an aged Hanson level controller.
I was advised by my Electronics Guru that electrolytic Capacitors will cause all sorts of LCD display issues etc. Once the reach about 10yrs of age, as the liquid inside them dries out.
It may not be of use to all but hopefully some of the guys when next trying to stabilise that errant readout.
May remember that if fitted? These style of capacitors may be at fault?

Worth knowing I think?

Possibly explains also why aged air conditioners with their multiple PCBs start failing at that age.

We had the Clavinova piano stop working a couple of years ago and, as it was 12 years old, Yamaha would not support the model and suggested we scrap it (1300 new in '96) and buy a new one. Up to this point it was a great little machine.

I traced the fault to the power board but there my electronic skills stopped. Managed to find an expert on the net, sent the power board off to him and he sent it back, fixed, for the princely sum of 50.

Cause of the problem....1 x electrolytic capacitor - value 0.28p

Again nice possibility for some to make a good job/profit ... but, that's life ...<img src="http://www.refrigeration-engineer.com/forums/images/smilies/wink.png" alt="" title="Wink" smilieid="5" class="inlineimg" border="0"><br>

In the old days we used to replace electrolytics every 5 years on critical equipment because they 'dry out' and fail. They're also prone to bulging and failure if they overheat especially if they are relying on a nearby fan for draught cooling and it becomes blocked with dust. They should be more reliable nowadays but I can't imagine why it should still be a problem with new technology unless it's deliberate to build a lifespan into the equipment.

Had one of these little buggers burst on my computer screen card, luckily, it was still under guarantee so I got a new one for free.

Hi all
this is what we call "age engineering"
these days you can design a pcb board to last excactly the time you want it to .
ever wonder how companies can give a 3 year warrnty ?
best of luck to us all
