PIN CONNECTOR
CAUTIONS FOR ADJUSTMENT AND REPAIR
• Degaussing is always required when adjusting purity or convergence.
• The white balance adjustment has been done by a color analyzer in factory. The adjustment procedure,
described in the service manual is made by a visual check.
• Allow 20 minutes warm-up time for the display before checking or adjusting only electrical specification or
function.
• Reform the leadwire after any repair work.
Caution For Servicing
• In case of servicing or replacing CRT, high voltage sometimes remains in the anode of the CRT. Completely
discharge high voltage before servicing or replacing CRT to prevent a shock to the serviceman.
