Summary

Literature

No documentation is available online at this time.

Notes

The service schematic for the Sony CPD-100ES is mostly identical to this model, and it's a good reference for repairs.

This monitor will accept composite sync via the H Sync pin. It also supports sync on green.

Service adjustments to this (and other Sony PC monitors) must be done using Sony's DAS software, which is a DOS-based predecessor to WinDAS.
