Service Menu

Service menu can be accessed by: 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.

Known Issues

This TV can suffer from misaligned chroma and luma, which causes blurry edges on colorful objects. This can be corrected in the service menu on page 13 by adjusting CLVS.

RGB Mod

RGB modification status for this model has not been confirmed. The TV uses the Toshiba TMPA8873C jungle IC, which would need to be checked for RGB input capability. Further research into the specific chassis and chipset is needed to determine RGB mod capability.
