Please help identify my monitor.

Can anyone please help identify my monitor with these pictures. The Ultracade hookup shows it as a medium resolution, just want to verify that I need to use an ArcadeVGA card and what I should set it for as far as resolution goes. Thanks in advance.

Obviously I have not given enough info, is there somewhere else I need to look for a part number or something? I am concerned if this will work with an ArcadeVGA card and how I have to set it up so I dont break this thing.

Upon further inspection I think I found a part number and some other info:
JS270104-2192
Sony-R JS Dual Scan
Also seems to be a cable labeled "15k / 25k switchable connector"
does this help at all?
There is nothing else visible and I dont want to start messing with the boards as I know nothing about monitor safety.
I am assuming that it is set for medium res right now and that with my ArcadeVGA I am better off changing it to 15k?? Just very intimidated by the prospect of messing in that area.

If you can set it to 15khz, it's best to do so since 15khz has better support than Mid-Res monitors

Do I need to discharge the monitor to change the jumpers or is that area "safe"?

Most newer monitors will bleed off a charge themselves if unplugged for a few minutes. Even with that said, you should be safe with the unit powered off if you stay away from the big red wire. Keep one hand behind your back and you'll be fine.
(even in a worse case, if the monitor is unplugged the jolt from any shock you'd get would only last a split second. I'd be more worried about your hand jumping up into the neck of the tube than I would about the shock itself.)
15Khz is the way to go

Guys I appreciate the info and I want to switch to 15khz, just not sure which plug to move. See attached picture, this is the plug labeled 15khz / 25khz, in the picture you can see the left one, the right one and an available slot between them, I cannot get in there to read the labels, any idea which one I should switch?
Also I hooked it up with 25khz and I could not get a good picture, it would not line up on the screen properly and at times would have black areas in the screen, will switching to 15khz correct these issues? Thanks again.
PS, if anyone is in the Chicagoland / NW Indiana area I would gladly pay a few bucks for a service call....

Is one of those two wire harnesses the one labeled switchable?
Can you get a small (makeup) mirror in there to see?

You'll want to run 15Khz. Bottom line. You'll have to find a way to get a decent camera shot or find a manual for us to tell you what jumper to move.

I have a local TV repair guy coming tomorrow who is qualified to remove the board, I am guessing it will then be clear what needs to be changed??

I'm not sure why you would remove the board. You pointed out what is most likely connector that needs to be moved. It's either going to be a single connector to move, or a switch.
Stick a camera with a flash in there at an angle where it can see the top of the board, and snap a picture or twenty. Post the best result shot, we'll assess the situation and tell you what to move.
If I could nail down the exact model number from the numbers you gave I might be able to provide you with a picture of your exact chassis. I know you have a Sharp Image monitor. Judging by the trinitron tube I'd say the chassis was built by Sony. If you could provide a diagonal screen measurement we might get closer to identifying your exact model.

It measures 25 or 26 diagonal, I will try the camera trick.
In case you missed earlier in the thread I found these:
JS270104-2192
Sony-R JS Dual Scan
The cable I pointed out is labeled as the 15 / 25 jumper so I am very sure its just a matter of unplugging one side of it and plugging it into the middle slot, just cant figure out which side. I am not home to take more pics but this might help some:

I caught the numbers, they just don't tell me much. Sharp image had Kortek and Sony make chassis for them, and weren't very good with documentation on either side. The sony version has many flavors.

Judging from past expirience, I'd say the two connection posts that are closest together are the ones that get swapped back and forth. Leave the post/connector that is farthest to the right alone.

That was my logic, if its wrong will I fry the monitor?
Do I need to discharge the monitor to swap?
Thanks for the help also...

No, but unplug it to protect yourself from doing anything silly

Check it out, I found a picture of a sharp image that looks like mine and seems to confirm our thoughts. You can even see the label on the wires and they are jumped to what we believe is the 15khz setting, so I have to believe we are correct.
