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.
