i have a wg 25k7193 and found the trouble shooting papers on line im just having a hard time following them and dont under stand what im supposed to do read it. Its says things like check B+ (123v) at ic4, pin4, neck board, p202, pin 3. I have no idea what that means also what kind of voltage meter do i need to be testing the voltage? I just dont have a picture on the game and no HV to the monitor. Thanks for the help

hello,i have seen your other post as well.i would like to help but i am concerned that you may injure yourself as you do not seem to have any experience on monitors
the b+ voltage is a stable voltage that runs the high voltage flyback transformer,depending on chassis its normally around 115 vdc,getting a shock from this is not nice
now if you still wish to continue and understand how to use a multimeter as well as all the safety concerns surrounding this work then i will be happy to point you in the right direction otherwise you should consider sending your chassis for repair once you have proved the faults are on the chassis

I will certainly take you up on this kind offer. I have been all over the place looking at multimeters, cathode recovery unit & crt testers, cathode tube rejuvenator ect ect...
I have been looking for the correct links to help me get a grasp of all this.
Any light you might shed would certainly help.

I also saw your other post. There are voltages all over the monitor board that can mess you up, even with it turned off... also the b+ needs to be measured with the monitor on. The 'pin 4' and things like that they're telling you about are places where that particular voltage is present, so it's a place to measure it. I would suggest reading a walkthrough on capkit installation, along with the safety precautions, and more importantly read up on how to discharge a picture tube. When you read all that and think you have a good grasp on it, then you can start actually working on it.
Good luck!

Thank you for both of the posts. I am certainly reading and trying to understand all of this.
