Step by step procedures for Beam Landing are provided on Page 15 of the Service Manual and Page 3 of the Service Manual Supplement 1. CAUTION Turn Off set or put set in Standby Mode prior to Hand Degaussing. 1. Before all adjustments, age the set for 30 minutes at 30 Nit. This allows for picture rotation to stabilize after turning set on. Aging is necessary following any change in set position in Southern or Northern magnetic field. Note the position of the Corner Landing VR adjustments prior to start. These adjustment settings may be used at User’s location. 2. Before all adjustments, allow time to warm up the CRT. Age the set for 2 Hours prior to Beam Landing adjustment after doing any of the following: A. The L Board is replaced. B. Any of the components D1701, D1702, C1701, R1703, or R1704 on the L Board were replaced. C. The L Board was removed and reinstalled. Or if the L Board components D1701, D1702, C1701, R1703, or R1704 wire leads or solder lands were touched by the chassis parts, test probe, or other conductors. 3. Local Adjustment of Corner Landing VR ‘s can be performed at user’s location. (The VR’s may be adjusted to maximum during manufacture.) Note the position of the Corner Landing VR adjustments prior to start. These adjustment settings may be used at a future location.

Effected units have S/N below 1296040. Solution: Then, please perform the following procedure to check the Degaussing Coil and to replace it if necessary. The following part (or equivalent) may be required to complete this procedure. CAUTION The Degaussing Coil and associated drive circuits operate on 117 VAC. Direct body contact with any exposed conductors may be dangerous. Avoid body contact with these areas when power is applied to the unit. Check Degaussing Coil Condition 1. Examine the Degaussing Coil assembly to insure that there are no cracks, missing sections, or bare areas along the coil lead wires and insulator jacket. 2. Replace the Degaussing Coil assembly if any cracked or broken areas of insulation are detected. Verify Degaussing Coil Operation Turn unit On after it has been Off at least 1 Min. or more in order to operate the Degaussing Coil. A simple method to verify Degaussing Coil operation is to position the test monitor close to another operating monitor. Turn on the test monitor while viewing the picture on the other operating monitor. The operating monitor should exhibit a noticeable flutter in the picture while the test monitor is powering up.
