Replaced the ZD3 on the Boston Acoustics Soundware xs 5.1 subwoofer with a 18 Volt-1 Watt Zener part number 1n4746a. and works like brand new.

ZD stands for zener diode and used for exact voltage regulation. Take out a known good one and go to a repair shop to replace. Make sure that when you re install, the striped (polarity) markings are in the same direction!

I had the same problem with mine I found that when I took it apart the main board has some type of glue on the back of the board on top of the headphone jack solder connections I removed that glue and cleaned the solder connections I found that for some reason the glue is reacting with the solder and creating a short. My radio is working again.

Just fixed my PV1000 that would not power on. Verified 185vdc on bulk capacitors. Measured 11vdc on U5 (UC3842) from pin 5 (gnd) to pin 7 (vcc). Then measured 0vdc from pin 5 (gnd) to pin 8 (ref). This should be 5vdc. This means that U5 is shut down for undervoltage. Turned out to be two open resistors. R94 100k 2w and R77 33k 2w. Never would have guessed that as there was no sign of heat discoloration. They are next to each other between U5 the UC3842 PWM IC and Q3. This prevented the proper startup voltage for U5. Replaced them and I'm off and running once again. Hope this helps someone.

Do not worry about the milliamp.
As long as you use an adapter thats the correct voltage (you stated 12 volts), the end connector fits into the speakers and the polarity is the same, then you wont have any trouble.

I am also having the same problem. It was working fine until we moved. Plugged it in at the new house and nothing but a red light. Sub is green though.

donaldws1018 I was wondering if the static problem was resolved yet. I have a pair of the VR970's that don't sound so good either.

In DEC 1998 I bought a Gateway PC with a Digital Media Theater, P/N 7000787. In the meantime the speaker in the sub-woofer got damaged (because of age). Is it possible to disassemble the sub-woofer and replace the speaker?
Where can I buy the same or a very similar speaker for this sub-woofer? Thanks, Andy Szekely
