Notes
The service menu can be accessed as follows: Set volume to minimum, then hold the Volume Down button on the front and press "Info" on the remote. Items can be selected and modified using the channel and volume buttons. To cycle through pages of the menu, press "OK" followed by the channel up or down buttons.
When you are finished with the service menu, press "Mute" to save the settings and turn the TV off. DO NOT press "go back", as it can erase all settings and put the TV in an uncalibrated state! For this reason, it is important to write down or photograph the initial values.
This TV can suffer from misaligned chroma and luma, which causes blurry edges on colorful objects. To correct this, go to page 13 of the service menu and adjust CLVS.
