Title: Any other components to discharge?
Post by: IronChef on February 24, 2004, 03:21:22 pm

Have an old 17" monitor kicking around that I am going to use in a project.

I need to repair a cracked solder joint on the underside of the monitor PCB.  The pads go to the HV module (and thus directly/indirectly connect to the anode).  I suspect this is the cause of the video blanking out I get once the unit warmed up.

Now I have never discharged a CRT before, but have read and re-read everything and am well prepared (even will use surplus hydro gloves for added protection!).

But the question I have is there anything else I should discharge?  Mind you this monitor hasn't been plugged in for over a week, but there is always a charge lingering somewhere.

Any advice is greatly appreciated.

Thanks.

Once your tube is discharged you should be good to go (I say should because I have no idea what your monitor is) I was sweating like crazy the first time I did it--gets easier after that--just pay attention and don't let any kids/cats/dogs/wives in the room while you do it!

did you discharge into the ground on an outlet, or the chassis? I'm discharging my Nintendo Sanyo monitor this weekend (cap kit) and am undecided where to send teh voltage. I'm pretty sure i'm going to use the ground on my outlet in the garage, but other opinions are always welcome.

You ground to the monitor metal frame. Don't dink around with an outlet.

I guess I should bold that in the FAQ--thats the second person who thought of grounding to the outlet--maybe I wasn't clear enough...

Yeah, it scares me to think what might happen if you send the juice into the outlet and there is a wiring problem in the house with that ground.  Having the voltage goes everywhere else instead, wouldn't be fun.

with my cap kit they sent discharge instructions and said the ground on an outlet was a better choice   ???
