You need to look for a fuse or fusible resistor because it sounds like that's a possible cause of your problem. You cannot test without a good digital meter and you need a schematic. The schematic you will have to buy; if you do scan it and send a copy to me and I will do what I can to help you. Fusible resistors are rectangular ceramic parts about 1/4-1/2" or bigger, usually.
