Monitor has NO FRAME. Is that a problem? Danger? No ground?

I picked up a cabinet and the frame on the monitor is missing. I think it's a WG4900. The chassis is just screwed to the monitor shelf all by its lonesome and then the tube is screwed to some wood bracket thing up top. Is this is a problem? I don't think it has good ground because of this. Am I wrong? Anything to worry about?

I am building this cabinet for someone else and I don't want any problems down the road.

Thanks!
 
I would think that as long as a strap/spring crosses the back of the tube along the aqua then connects to the ground pin on the neckboard it would work. To assure a solid ground and enough of a path I thing I would back it up with a connection from said strap (or an ear on the tube) back to the metal pan the actual chassis pcb is on.

Agree you don't need the frame if the aquadag is in contact with a spring or strap that grounds to the chassis/neckboard...

i just picked up an early Japanese convert-a-cab and that's the way the original monitor came... no real frame and the chassis screwed down to a shelf under the tube.
 
That's how a lot of the Midway black & whites were....Ever see the inside of a Midway Space Invaders?

The frame is just there because it's far more convenient to swap a monitor as one piece than as two. It's also more convenient for Electrohome/WG to sell a monitor as one piece...

The grounding is provided by the ground strap along the back of the picture tube, which is connected to the chassis by a wire.

Television sets don't have a metal frame, nor do computer monitors. The picture tube is just bolted to the plastic faceplate. Grounding is still provided by a ground strap along the back of the tube, and a wire to the chassis.
