Anyone have a picture tutorial on how to replace the HV diode in a 19v2000? I found this link, and it was helpful but it was for a g05. Any other tips on replacing the diode?
Thanks,

Thanks for the input guys. Good information. I haven't worked with a vector monitor, so it's all new to me. I haven't taken apart the monitor yet, but the guy who sold me the game said it needed a new HV diode. Just trying to do my homework before I start on it.
What do people use for the "grease" after you clean it?
Thanks again,
Theron
My initial thought was do a cap kit, replace the transistors, clean and regrease the HV diode, and see what happens from there.
I pulled the monitor out yesterday, and would like to order parts today for it. Do people recommend replacing the filter cap (C101 & C102) as well as the ones in the kit? I plan on ordering a cap kit from Bob Roberts along with the 4 transistors for the frame.
Is there any way to test the HV diode? I have read that it can't be tested like a normal diode.

Thanks for all the advice. I did a cap kit, replaced the filter caps, and replaced the transistors on the frame. I also cleaned and reinstalled the HV diode.
I plugged in the monitor, and didn't see any glow in the neck. The red LED is lit (spot killer?). The fuses are good. The game will play blind at this point. The previous owner said it needed a HV diode, because he shorted the tube to the frame without 1M resistor. The HV diode looked good, but had no way of testing it. I tried testing on ohm settings and got OL both ways.
Does a HV diode only cause blooming or would it cause a monitor not to work?
Any advice on the next step?
Thanks again,
Theron
bumping up this old topic to ask if anyone can say one way or the other whether it is possible to test the HV diode? someone must have figured this out by now.
