Voltage Fluctuation In SMPS

[tvtech]

I don't think I've ever had to replace one?, exceptionally reliable devices, but of course they aren't under any stress, nor in a position to get 'fried' very easily.

True Nigel

Only three times. Solved the problem though.

My conclusion is I don't scratch there anymore.....unless I am really stumped and don't know what else to do....and the symptoms are the same.

Rare stuff. Only available at ETO.

But interesting still

Hell, I am tired. See you Tomorrow.
