Hi folks, I have a 21" EIZO CRT that had some retrace lines so I lowered the G2. It looks good now but I recently bought a multimeter and want to make sure all the voltages are in spec (I have the service manual).

Problem is, when trying to measure G2 the screen will dim a lot and there will be various sparking sounds coming from inside the CRT. I am somewhat afraid to keep the meter on the point long enough to take an accurate reading in order to not burn something out. I am not sure if this is supposed to happen.

I tried the same thing on a much smaller Goldstar TV - wired the negative to the bare metal wire that goes across the picture tube and the positive on the G2 spot, and the picture also dims a lot but there is not nearly as many nasty sounds (only perhaps some slight sizzling) and I have managed to get a reading there of around 365 VDC, which I don't know if that is an OK G2 for a small TV (around 14-15").

Here is a picture:

Thanks!
