damn, true i should have gotten higher values. I actually did buy some accidentally but then had my order changed from the 6kv ones to the 3kv ones.
my 50kv spark gap ignitor was the only high voltage power supply i had available to test with.
The silicone i wound up getting was neutral curing clear stuff. Not especially UV resistant nor especially resistant to mold. Basically just pure and clean.
I did a test, all 6 capacitors on the board had different readings. although my multimeter barely reads 15pf, it did allow me to see some are wearing out.
i also made a new developement in hunting the fault. It seems when the wires are leaking HV, and in the dark i can see a corona discharge, arcing into the grounded back board, the monitor works. When the wires arent allowed to do this, there is no noise, and no backlight starting up too, its like its triggering a over voltage sensor in the backlight circuit somewhere.
the backlight inverter has 6 CCFL tubes i believe, since there are 6 outputs.
When the backlight is up and running, the noisy arcing stops. i can however still see some violet glow comming off the other 3 of the 6 leads where they are all bundled together. These gave readings which suggested they werent failing.
anyway though, point is, the silicone i have now appears to be working, but now the problem has spread or is at least being shared elsewhere. I might post a new thread somewhere else about this since ive done allot of studying on it and i need to explain everything before asking for help on it.
