COLOR TELEVISION RECEIVER TC1973D Irr! 0 ... 1 SPECIFICATIONS 1 UHF CATV All the specifications and features are subject to change without notice. DISASSEMBLY INSTRUCTIONS 1. REMOVAL OF ANODE CAP Read the following NOTED items before starling work. After turning the power off there might still be a potential voltage that is very dangerous. When removing the Anode Cap, make sure to discharge the Anode Cap's potential voltage. Do not use pliers to loosen or tighten the Anode Cap terminal, this may cause the spring to be damaged. 3. After one side is removed. pull in the opposite direction to remove the other. NOTE Take care not to damage the Rubber Cap. INSTALLATlON 1. Clean the spot where the cap was located with a small ' amount of alcohol. (Refer to Fig. l-3.) REMOVAL 1. Follow the steps as follows to discharge the Anode Cap. (Refer to Fig. l-l.) Connect one end of an Alligator Clip to the metal part of a flat-blade screwdriver and the other end to ground. While holding the plastic part of the insulated Screwdriver, touch the support of the Anode with the tip of the Screwdriver. A cracking noise will be heard as the voltage is discharged. GND on the CRT NOTE Confirm that there is no dirt. dust, etc. at the spot where the cap was located. 2. Arrange the wire of the Anode Cap and make sure the wire is not twisted. 3. Turn over the Rubber Cap. (Refer to Fig. l-4.) GND on the CRT Fig. 1-l 2. Flip up the sides of the Rubber Cap in the direction of the arrow and remove one side of the support (Refer to Fig. l-2.) Rubber Cap Fig. 1-4 CRT V Support Fig. 1-2 4 DISASSEMBLY INSTRUCTIONS 4, Insert one end of the Anode Support into the anode button. then the other as shown in Fig. I-5. Fig. l5. Confirm that the Support is securely connected. 6. Put on the Rubber Cap without moving any parts. 2. REMOVAL OF DEFLECTION YOKE (Refer to Fig. 2-1) I. Loosen the screw 0. 2. Remove the Convergence . Purity Magnet in the direction of arrow (A). 3. Loosen the screw 0. 4. Remove the 3 Wedges. 5. Remove the Dellection Yoke in the direction of arrow (8). INSTALLATION tnstall new Deflection Yoke in reverse steps of REMOVAL. NOTE After adjusting the purity and the convergence. fix the screw 0 and lock the wedges. Wedge Fig. 2-. 5 ELECTRICAL ADJUSTMENTS 1. BEFORE MAKING ELECTRICAL ADJUSTMENTS Read and perform these adjustments when repairing the circuits or replacing electrical parts or PC6 assemblies. CAUTION Use an isolation transformer when performing any sarvce on this chassis. Before removing the anode cap, discharge electricity because it contains high voltage. When removing a PCB or related component, after unfastening or changing a wire, be sure to put the wire back in its original position. Inferior sillcon grease can damage IC's and transistors. When replacing IC's and transistors. use only specified silicon grease (YG6260M). Remove all old silicon before applying new silicon. 1-l: Prepare the following measurement tools far electrical adj
