taking apart a TV - bad idea?

>Just because the capacitor is a 350volt capacitor does not mean it was charged to 350volt.

In addition, it does not equate to destructive energies. I regularly test stuff with ESD guns that generate 15,000 volts - but since the total charge is low there's not much danger (though it does hurt.)



Zowie! I've had a disconnected laser power supply sting me a bit too (Telxon handheld scanner).

I know it doesn't have to be high voltage to hurt. I got bit by the 28-volt circuit on an aircraft once - I learned and didn't let it happen again. I also got hit with 450-volts when I disharged a capacitor bank through my arms and chest. Put me on the floor very quickly and I couldn't get up for quite some time because my arms wouldn't work to help me get up. Scariest part was I was alone at the time and wasn't expected to be anywhere with anyone for several hours.



YIKES!

9/10 it'll be the solder/tracks on the EHT coming loose. Symptom is usually that you can turn it on, but just don't get a picture (ie, you get a green light). It's easy to fix with a soldering iron, fixed dozens of TV's this way. Always used to happen after a TV had been moved.
