Notes

The flyback in this model is a valid replacement for the Sony GDM-FW900. Looking at the part numbers they are very similar (NX-4504/J1D4 vs. NX-4502/J1D4) and the schematic shows they have the exact same pinout, and the nearby circuits each pin connects to are close enough to be considered compatible.

Brightness issue

There is a common problem where these monitors are too bright and the OSD controls don't allow you to correct it. In that case you need to use WinDAS to lower the G2 value in the monitor's firmware settings.
