Windows 7: New monitor

Ah I was thinking or rather trying to imagine you taking the monitor to pieces ( that would have pleased someone near and dear) and it was the PSU (so to speak).

Hope you took the right precautions my friend as they are quite dangerous things as I am sure you will know even at low volts the current is the killer. Yep I knew about the capacitance logic as I built a few scanners when I was younger for detecting solid or metal objects behind wall linings.

I have just done some extensive research and testing on getting the charge out of PSU's before dismantling them for whatever reason. We are currently (no pun intended) working on a device and / or method of safely discharging the caps in PSU's in order that it minimises at the very least and preferably negates the danger of dangerously high voltages and currents being present when any individual is working on a PSU/s.
I also gave Britton some information to be put into the really well done and laid out tutorial he did if you are interested.

I am a RN by profession and have some knowledge of the physics behind heart monitoring and cardiac arrhythmias which is why I am trying to work out a solution because of the problem of still charged fully or partly caps in PSU's interfering with the hearts "electrical" system.

So please anyone reading this take note these devices are dangerous even when slightly charged - at worst they can kill - at least give you a nasty shock and / or burns!

Now I shall get off my soapbox LOL!!

Windows 7 x64 and numerous virtual machines

Yep, been repairing electronics since 1975. Always very careful with switch mode power supplies and the 400V working capacitor with 350volts DC sitting on it. Been shocked a few time, nothing serious though as I keep one hand in my pocket so the shock cannot go right across my chest.
The capacitors that fail are usually the low voltage ones. Sometimes if the screen does not light the inverter caps may have gone open. Had that on numerous LCD TV power supplies.

Well Indie seems like we have a few things in common - I've tinkered for want of a better word with electronics since 1960 but most of the stuff I was interested in was audio and filtering circuits.

I did some tests recently that I will not broadcast in here because it is too much of a risk and I urge anyone who reads this post to please take extreme care when handing a PSU in any way shape or form . This goes before saying and I think even if the PSU has not been touched for a very long time, and especially if it has been used within the last year. In fact I would go as far as to say that a PSU is best left to a qualified person to deal with unless it is brand new and never been used.

The last statement may be a little overkill but for the unwary better to be safe and alive then fool hardy and dead.
