Question about ElectroVoice SxA180 Subwoofer

1 Answer

No sound I've had recurring problems with the thing seemingly not starting up when I first power it on. It's like it's not even getting power. And since it has NO pilot light, you really can't tell whether it's getting power or not. Quite often, I fiddle with everything (cabling, etc.) for anywhere from a minute to 10 minutes, and then suddenly it's working and I don't really know why it wasn't before or whether the problem was even internal to the sub. Very frustrating.

Check the power supply filter capacitors - leaky caps / noisy supply / low voltage may not let the protection relay to energize. With a few minutes ON time, the caps may form - allowing the voltage to stabalize, and the relay will kick on. ( Just a guess )

You may need a 'heli' coil or a larger Spark Plug, it seems that the vehicle at operating temperatures is building up too much pressure and pushing out your current sized plug! Same thing happened to a me! And if its too much pressure, there is a 'filter' that becomes restricted, easy check!
Hopes this helps!

My iPod isn't working.

Okay. It seems like your iPod is stuck. Hold the home and power (screen lock) button together for around 10 seconds. Your iPod should reboot. :) If even after reboot, problem recurs repeatedly, it's a software problem. Restore it using iTunes or take it to you nearest Apple Service Center.

You need to check it is mechanicaly sound, a compression test will give you a good idea, anything under 110 psi and you have a problem with either piston/ring wear, or it has seized.

fuel pump sounds to be problem, though I'd replace air cleaner first to rule it out cheaper than pump (pump may have internal filters that are blocked)

My problem is the same as the rest of these, My T9100 has lost the driver for the Yamaha AC-GX sound device. It worked find until I installed XP SP2, I've been to various forums and followed...

The 9100 series are famous for this problem, and it's more than likely hardware related and not driver related: the connector on the motherboard (where the sound card connects to) is probably loose - so it's not seeing the sound card (or only seeing part of it). Problem is probably caused by chassis flex over the years, and it's pretty common.

Solutons? Dunno... I've fixed about a thousand of these but over the years, about 1 out of 5 had the same problem recur, and I'm tired of fixing these things. Cheapest workaround? Get a cheap USB sound card and a cheap set of laptop speakers (cost me about $4 total) - a little cumbersome, but it don't cost anything....

I have read all the msg boards and am still not able to sync my iphone 3gs to outlook. does it have anthing to do with running Vista? I used to work then notice that it changed

Vista shouldn't have anything to do with it, unless your using a 3rd party software to connect it.
First thing, Update iphone to latest version.
Update outlook 2007 using windows update.
The resent update to the iphone firmware and itunes fixed the problemof things not moving from iphone back to outlook.
BEFORE the fix for the iphone , to get an event to show up back in outlook , you would need to make it a recurring event on the iphone starting and ending on the one day ...
to test if thts the problem you have , make a new calendar event in your phone and make it recurring, starting and ending on the same day.
sync, then check outlook.
Before this update to get things working I needed to do the following...
1) backup your outlook .PST file. 2) rename and move the existing pst file, and create a new one.. 3)import the contacts 4) import calender events, (not recurring ones) 5)sync.
BEFORE the fix for the iphone , to get an event to show up back in outlook , you would need to make it a recurring event on the iphone starting and ending on the one day ...

F7 and then clock is lit up. The key pad for upper oven is locked. I can'tget it to do anything. Before this it came up bake at 350 degrees and push to start. I did this, even I didnt want oven on. I also...

OK, this code is signaling an issue concerning the key pad or control board.

Determine if problem is with the Key Panel or Control by:
1. Pushing CLEAR/OFF pad.
2. Disconnecting Ribbon Cable from control and waiting at least 32 seconds to see if Code recurs

If code recurs, problem is in the control. Replace control.

If code does not recur, problem is with the Key Panel.

Dell w2600

There is no fix for the W2600. It has a power supply problem.
For sometime Dell was replacing the tv's with new ones, but don't think they are anymore. If you go to the Dell Forum and type in your tv you will see the amount of people that have had the same problem. Unbelieveable. As a matter of fact, Dell is not even making TV's anymore. Guess they gave up. They cannot be fix, cannot get the parts for it.
