Continuing this from the welcome to DKF thread, since this seems a more appropriate place.
Very nice red, cab! Yours is better than the one I just picked up a couple weeks ago. You have what appears to be the original CPO, bezel and marquee (no C Nintendo of America 1981 on yours). Mine has original marquee, but bezel and CPO are replaced.
The only thing that stand out as odd is the red ball top on the joystick. Weren't all original ball tops black?
If you look at the back of your bezel, is it a white outline, with tinted film creating the tint?
What version game board is running in your red cab? Please send pics of that, if you would, and also of the serial/part number metal nameplate.
Maybe this would be better to take to a separate thread, since it's a bit outside of the scope of "welcome to DK Forums".
I would love to jump in on a thread, with comparisons of red cabs among the members of DKF.
:edit: Just zoomed in on your picture of the back of the cab. You've got an original TKG2 converted Radar Scope board set.
Does the title screen say C Nintendo 1981 or C Nintendo of America 1981 ('C' being the copyright symbol)? Oh yea, you don't know cuz the monitor ain't working. In addition to V and H hold, there are three brightness controls, one at the flyback, one on the chassis, and one on the remote board. You may need to mess with those to get a good image, too.
