Notes
This generation of Trinitrons is not completely compatible with later Sony remotes. While basic controls such as channel select, volume, and power are the same, picture adjustments cannot be changed from the front panel and require "Select" and "Picture +/-" buttons that are missing on newer remotes. Obtaining an original remote is essential to properly enjoy these TVs.
Unlike later models, this chassis design does not have a service menu, and all adjustments are done via trim pots on the chassis. It was also one of their last TVs of this size to include a pincushion correction circuit, and has adjustment pots for horizontal geometry.
Despite having A/V inputs, this TV uses a hot chassis design and should not be modified for additional inputs. Instead of isolating the entire TV, the input signals are transmitted using optocouplers.
Hot Chassis means that "ground" on the chassis is tied to one side of the AC input from the wall, and touching it with your hand will complete a live circuit through your body to earth ground if the CRT is plugged into an AC outlet. The proper way to avoid this danger is to use an isolation transformer to isolate the CRT from earth ground and prevent electrocuting yourself.
