These didn't do anything, checking the amp I found the o\p transistors were s\c replaced them and the speakers worked but the sound was not quite right. The surrounds needed replacing. A common problem is the tantalum capacitor in the middle of the power amp board becomes a resistor and stops the amp from working as it should, the large supply capacitors were replaced as they had leaked.
