CT-13R52 This Service manual is issued as a service guide for the models of the NA7D family listed above. Included are schematics, alignment procedures, disassembly procedures, and a parts list.
Important Safety Notice Special components are used in this television set which are important for safety. These parts are identified on the schematic diagram by the symbol and printed in BOLD TYPE on the replacement part list. It is essential that these critical parts are replaced with the manufacturer’s specified replacement part to prevent X-ray radiation, shock, fire or other hazards.
Service Notes Note: Some components may be affixed with glue. Be careful not to break or damage 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.
IMPORTANT: To protect against possible damage to X-Ray Protection Circuit Check & the solid state devices due to arcing or static discharge, Adjustments make certain that all ground wires and CRT DAG wire This test must be performed as final check before the are securely connected.
Specifications are subject to change without notice or obligation. Dimensions and weights are approximate. * Note: When ordering a replacement board assembly, append an “S” to the board number. Example: to order the A-Board for CT-13R32E, the replacement board is TNP2AH024ECS. - 6 -...
