usually its the bash chip the HC1011, there are two of them, try gently pushing on one of the top corners, if the noise goes away then the chip is bad, it might work for a short period of time. I bought two replacements from JBL, look in this forum for the number to call they cost about $25 each. One is for the sub, the other is for the satellite speakers, the chip with the back facing outwards, where you can read the part number is the one for the satellite speakers.

what is the value of R19 in the above picture ?? mine is a little bit burnt, and I pulled one leg and measured 26.10Kohm, is that close ?? Oh BTW my bash1011 board does the same as all the rest, causes a whining-screaching sound unless you bend it a little by pressing one corner or the other, but it doesnt last for long. -CHUCK
