The pattern will shrink in size then disappear In approximately 2 3 seconds the pattern will reappear at about half size and continues to increase in size and brightness until it is full size then the cycle will repeat As the pattern decreases the circuit time constraints prevent the protect switches from activating When the circuit allows the switches to activate they will not turn on until the brightness and deflection reach the design limits This is when the pattern reappears at about half size Audio Amp Check Select the Sound Test and with the volume control set at mid range monitor the audio Sound chip channels A B C and CPU sound test signals must be audible with no notice able distortion IX CRT YOKE REMOVAL AND SET UP CRT removal replacement and set up is the same as most B W TV tubes in most respects The primary difference is in the centering technique After the CRT yoke has been installed do a preliminary centering using the test cartridge linearity pattern for a display and the centering ring magnets on the yoke The next step is to set the DAC ZERO as directed in Paragraph Il of the LOGIC BOARD ADJUST MENTS After that is completed again recenter if necessary with the ring magnets on the yoke Adjust vertical and horizontal height so the linear lines are at the top and bottom left and right edges of the CRT and front cover Also see R401 and R408 X HAND CONTROL DISASSEMBLY Remove the Hand C
