This is the main PCB from my Sanyo JA-289. Were I replaced two leaked caps with the two dark blue ones and one of the resistors in series with those caps got high impedant. Since that is a frequency depending network, the chanel were ths resistor was didn't work. Instead of 2.2k it had someting in the M-ohms. I replaced the 2.2k 0.5W resistor with two 2.2k 1/4W resistor in parallel and then again in series.
