It looks like you may have a small diode with a broken lead. You will need to know the voltage of the light circuit and if the LED replacements can be used with that voltage. You can't just throw in LED's in the place of incandescents and expect good results. The service manual may list the voltage of the light circuit.

It just occured to me that I've relamped a 2270. I used incandescent replacements since LED's will not broadcast a steady glow like original. IIRC, there are also some small bulbs for indicator lights.
