Summary

Despite the name being so close to the KV-13M10, this is a newer chassis revision (BA3) which is not RGB moddable. The OSD is digital RGB and the chroma chip cannot be swapped with any other known model number to get analog RGB capabilities back. Despite this, the chassis can still be S-Video modded fairly easily, which still allows for very good picture quality on a 13" tube.

Manuals

Notes

The inside sticker mentions that this chassis is compatible with both the A34JBU70X and A34JBU10X tubes - which suggests these tubes are swappable. You may be able to use this 70X tube as a salvage for a PVM that takes the A34JBU10X tube.

S-Video Mod

  1. Remove the jumper which is in the position labeled R308. You can either cut this with side-cutters or desolder it.
  2. Connect your Chroma input signal wire to the top pad of R308 which leads to the chroma jungle (see image).
  3. Connect your Luma input signal wire to the input pad for Composite Video (see image).
  4. Connect your Ground wire to the ground pad for Composite Video (see image).
  5. Enter the service menu by (while TV is off) pressing the following sequence on the remote, one at a time: Display + 5 + VOL-UP + Power. Scroll the settings with 1 and 4 on the remote until you find "CROM" or "CTRP". These should be set to 0, if your service menu has them.

Whenever an active s-video inputs source is connected, it will display using the composite video input switch on the front of the TV. Don't have consoles connected to both input sources at the same time, otherwise your signal brightness may be raised/lowered dramatically due to termination problems.
