Try downloading MidiOx and troubleshooting with it. It will show you if you have any midi activity and which channel your Casio is transmitting on etc.

The answer is repair shop if you don't have tools or experience with soldering. If you do it is simple to take it apart and take the old supply jack out. Take it to an electronic parts supplier so they can match a new one up for you. Make sure that the holes in the circuit board are clean and free of broken pins. Make sure that the traces leading to the holes are intact. Do not use too much heat or they will separate from the board. It might help to take the adapter with you as the jacks and plug have to match in size.

The keyboard is LIKELY scanned as a matrix.

You have two problems:

The contacts in the Thomas will have to be totally disconnected rendering use of any of the Thomas organ unlikely.

The second problem is that the keyboard LIKELY has velocity sensing. This means TWO contacts must be used PER note. One contact "makes" first and "breaks" last. This is used for velocity sensing on synths. The Thomas foot pedals likely only have a single contact per pedal, and even if they had two, it is unlikely they sequentially close..

The matrix scanning is accomplished by sensing the connection of two crossing points on a matrix of circuit lines. USUALLY each of 12 wires tie to all of one note across the board. Then two other lines for each octave "strobe" the first make contact and then the second of those strobes the second make contact. There are two of these strobe lines for EACH octave on the board.

Remember that these lines scan at digital logic speeds so wire length and NOISE/STAIC DISCHGARGE PROTECTION is a must.

SOURCE: not able to connect to USB MIDI of my Casio CTK 810i

On reading specs, use of the USB is NOT supported on a MAC or on other than the 32 bit version of Vista. If you happen to have the 64 bit Vista, it won't work. All the other versions of Windows seem to be supported..

SOMETIMES one must install the software BEFORE connecting the USB cable to the unit. SOMETIMES one must install the drivers in SAFE MODE. These things are ridiculous, but some of the quirks of Windows are stupid.
