I'm having trouble with a EYGO UCS-13CS-28SR or a merit megatouch type 2 monitor.When powered up it is constantly arcing inside the tube socket on the neckboard.I can't figure out if this is something with the flyback or just the neckboard.Can i take the tube socket apart and repair it if this is the problem or are replacments available.
Thanks folks
 
If the arcing is in the area where the white wire plugs into the plastic housing around the tube pins in the neckboard, I had the identical problem. That wire is secured in place with a tiny plastic wedge that had worked loose. In my case, there was no picture because several components had been blown due to the arcing. Unfortunately, I don't remember which ones. I do remember that having it repaired by a pro was darn near the cost of a new chassis.
 
The arcing is in the square part of the housing where the white wire goes in.After reading these replys i went and pushed in on the white wire.I had spark,then neckglow and then it went back to arcing inside again.It looks like i can pop the top off that housing.
 
If the arcing is inside the tube then you have one of these problems:

1. Air in the tube. Either a gassing issue or a crack somewhere.
2. Short in the tube. Try to remove it using a CRT Rejuvenator.
3. Short or bad winding in the flyback transformer.
4. Shorted cap on the focus line on the neck board.
5. Bug or some foreign object in the tube socket.

Good luck!
 
It is not arcing in the tube,it is inside the white socket on the neckboard.Actually it arc and makes a loud squeeling whining noise.I got brave and removed the socket from the neckboard and took it apart.The 2 parts inside were black but in good shape,so i cleaned them and reassembled the unit.When i powered it up the results were less dramatic than before,quieter,smaller more orange arcing rather than the bright blue.I'm attaching a pic if it shows up lol,of the 2 parts that make the gap where the arcing is happening.I guess what i need to figure out is,are these parts doing their job just fine and maybe a lack of somewhere for all the juice to go is causing this or some other problem.These parts look fine and not worn.
