X-radiation emissions. For continued X-radiation protection, the replacement tube must be the same type as the original, Sharp approved type. When troubleshooting and making test measure- ments in a receiver with a problem of excessive high voltage, avoid being unnecessarily close to the pic- ture tube and the high voltage component.
61R-WP5H 55R-WP5H SERVICING PRECAUTIONS CAUTION: Before servicing instruments covered by this 7. Do not apply AC power to this instrument and/or any of its service data and its supplements and addenda, read and electrical assemblies unless all solid-state device heat- follow the SAFETY PRECAUTIONS on page 3 of this sinks are correctly installed.

IC Removal/Replacement 4. Securely crimp each connection and solder it. Some Sharp unitized chassis circuit boards have slotted holes (oblong) through which the IC leads are inserted and 5. Inspect (on the circuit board copper side) the solder joints then bent flat against the circuit foil.
Page 10
61R-WP5H 55R-WP5H NOTE: These components are affixed with glue. Be careful not to break or damage any foil under the component or at the pins of the ICs when removing. Usually applying heat to the component for a short time while twisting with tweezers will break the component loose.

61R-WP5H 55R-WP5H Geometry Adjustments and Sequence (1) Base Geometry Green Raster: Raster inclination, position, vertical size, and horizontal size must completed first. This requires using input 5 with a Monoscope or Crosshatch pattern of 1080I format and with View Mode set to "Stretch". Adjustments are done using the deflection yoke centering magnets and the Service modes D01, D02, D07 with the DI wire unplugged on Deflection Board (DUNTKA233).
61R-WP5H 55R-WP5H SERVICE ADJUSTMENT 1. Raster inclination adjustment (Deflection yoke) Base raster adjustment Adjustment preparation (1) The set can face east or west. (2) Input the single cross test signal (1080I component video, TV in stretch mode). (3) Set video conditions to standard mode (STD).
Page 36
61R-WP5H 55R-WP5H 3. Vertical size adjustment (D02) Adjustment preparation (1) The set can face east or west. (2) Input the single cross test signal. (3) Set service mode to D02 position. (4) The lens focus adjustment should have been completed.
Page 37
61R-WP5H 55R-WP5H 5. Beam alignment Adjustment preparation (1) Adjust at least 30 minutes after turning on power switch. (2) Demagnetize the CRT mounting bracket. (3) Raster inclination, centering, horizontal and vertical amplitudes and optical focus adjustment should be completed. (4) Set video conditions to standard mode.
Page 38
61R-WP5H 55R-WP5H 7. Static focus adjustment Adjustment preparation (1) The raster inclination, centering, horizontal/vertical amplitude and optical/electrical focus beam alignment should have been adjusted. (2) Set video conditions to standard mode. (3) Receive the cross-hatch pattern signal. (4) Apply covers to the lenses of colors other than the color to be adjusted and project a single color.
Page 39
61R-WP5H 55R-WP5H 9. Raster position adjustment (static convergence) Adjustment preparation (1) Position adjustment — This will move an entire color. Use this adjustment to match colors at the center of the screen. (Active video center from external signal and physical screen center should now match from phase adj. 8.) (2) Use the buttons below to switch color to adjust.

61R-WP5H 55R-WP5H Adjustment procedure (1) Start adjustment at the center of the screen. (2) Continue adjustment at next closest position. (3) Adjust center area first, and ending with edge sections. (4) Press the INPUT button to perform interpolation operation. This process will take about 1 second and no picture will be seen at this time.
