Summary

Premium 27" TV from the early '90s with a very unique chassis design. It features an S-Video input, detachable speakers, and A/V outputs. Among the first Sony TVs to use an OSD service menu, which is accessed by a "service mode" switch behind a hole in the back of the case. Very easy to modify for RGB.

Notes

This model appears to use the same chassis design as the KV-20EXR20, and can be modified for RGB input using the same method.

An original remote (RM-103Y or RM-104Y) is requires to access the full range of options on this TV. It has "video" and "audio" buttons for selecting picture & sound menu options, which are not found on most Sony remotes.

Service menu is accessed by pressing a pen into the unmarked hole in the back near the S-Video input - with the button pressed down, press Power on the remote (or the front of the TV). Now you're in service mode.

Support for 50Hz video can be enabled by adjusting "VSMO" in the service menu.

From there, you can navigate the service menu like many other Sonys, using 1/4 for scrolling the options and 3/6 for scrolling the values. To save your changes, press MUTING then ENTER, then unplug the TV from the wall.

If you see vertical bars/shadows on the left side of the screen, replace C704, the 4.7uF 250V capacitor on the neckboard.

In the video settings menu, there's an option to toggle a Notch filter. This may be beneficial for some video game consoles using Composite.
