blown cathode ray monitor tube
« on: November 26, 2006, 10:25:59 PM »
Hello. Can anyone tell me what gases are released from a monitor picture tube when it blows? I think I had this happen to me yesterday while installing a new monitor. I turned it on, and half of the screen (from the middle down) was black, and there was an abundance of very noxious fumes. I wasn't able to reenter my office until this afternoon. I know these things contain all sorts of nasty substances (lead, cadmium, hexavalent chromium, etc.), but what exactly are the fumes? Thanks in advance.

I doubt it was blowing CRT, more likely high voltage unit, or even just power unit - and the smoke was that of burnt insulation. No heavy metals, but can be stinking as hell.

I believe cathode ray tubes are vacuums. Therefore no gas was released. I have to agree with Borek.
