Joe, First,....change the "5" in the model number to an "S". Now,... to determine which module is bad, first check pin 3 of plug 3AG for between 3-16 volts. Then check pin 5 of plug 3AG for a 5 volt p-p signal, or 4.3 VAC. Check across RX3407 for 130 volts. If any of these voltages are missing, replace HV board 9-1047-01 (or repair board as needed). If OK, check pin 6 of plug 3AG, should be 3 volts. If missing, replace 9-1055 board (or repair board as needed). If OK, check pin 1 of plug 3AG for 16 volts. If missing, replace 9-1047-01 (or repair board as needed).
Some of the C3 chassis fixes for dead set condition: Check or replace the following: C3407 ([EMAIL PROTECTED]), CR3415 (14 volt zener), CX3432 (100 @ 100), and C3440 (3.3 @ 50). Also,...I have the factory service lit. on this set. (Paper,..and micro-fitche). It is a C3B chassis, and the service Lit. is CM-147/C3(E), and (G). If you need it, let me know, and I will send it to you,....SNAIL mail (Monday A.M.) !!!! Good luck, LLW LeRoy Westlund Westlund TV & Electronics 97 North Main "Where there's a will,...
