Question about Sony SA-WX700 Subwoofer

1 Answer

Sony SAWX700, powers on fine, subs are not blown but no sound

The subs are ok, this model is known for this issue, its the board (amp) repair shops wont fix it down to the component level, they just want to replace the board. any idea how much that would cost? should I just buy another sub... I must say I'm dissapointed with Sony as of late... I think I'll stick with Yamaha and Polk from here on out :)

The problem may be with the preamp power supply section. Easy fix in most cases. This is a great sub, they don't build them this well anymore. From Sony, I was quoted around $200 plus the bad board in exchange. The part to fix it costs $1.00, labour an hour or less. Get it fixed. The other brands have gone cheap with components and build quality. Let me know if you want more info.

I have a 4 year old RCA Model # HD52W59 HDTV that just developed a convergence problem. Besides seeing all three colors the picture bow's inward on both the top & bottom of the picture. When you...


Hi


Thanks for using FixYa. This is often caused by failed convergence ICs. I don’t think the issue is with the power supply of the unit as the sound is coming fine from the unit. It’s not a difficult job if you want to do this yourself, you should require some basic knowledge about soldering-resoldering components. To start with you’ll have to open the back of the unit and then replace the ICs (STK ICs) which are located behind the black heat sink and also check the resistors as if they are short the ICs might blow again after sometime. There are
repair kits available which includes repair instructions with the parts, if you want to do it yourself, you can buy and repair it yourself. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks

When my jbl psw-d112 is on it will run just fine for a few min then it will sound like the speaker is blown. the green power light that is next to the vol level knob starts to turn red. What does this...


That model is known to have issues with the amps.Your problem is caused by a couple of components on the board shorting out.If you pull the amp out you will find on the large board behind the speaker terminal a couple of burned components.

The easiest fix is to buy a Bash 300w amp from Parts Express and replace the original amp.The Bash amp fits pretty well except that it is about an inch shorter.You can fill the hole with some mdf and have a sub that actually performs better than the original and with less heat build up as it is digital.Hope this helps,it's not complicated really.

I need a new power amp for a JBL PB12 Subwoofer


Alf, when there is no parts available you have to start looking at local non authorized repair shops that will inspect and repair the board instead of trying to source a replacement board.

This can be very difficult and could make for alot of expensive deposits. Running out of parts is an ongoing problem with all electronics and sometimes replacement is the most cost effective option.

Cheers,

Kevin

Some basic trouble shooting is required here. First you need to see if it is a problem from your source or the sub. Try a different source to the sub-woofer and see if it changes the response. If still nothing on the sub, then most likely there is an issue with the amp or driver. Check to see if there is a fuse on the sub, if so, it could be blown. There could also be an issue with the auto switching circuit on the subs amp, in that case, it would need to be repaired in the shop. But before that I would check all of the connections to the sub, and also to the driver in the cabinet. If everything looks good, then put some type of source directly to the woofer to see if it works, if you get sound, then looks like the amp has a problem. Again a repair or replace issue.

Power on/off


solidus- Your amp is going into protection mode, try disconnecting the sub and see if the power will stay on then.If yhe power stays on,it is your sub-blown or shorted ect. But if it does the same as before,its to the repair shop. cooltek Mar,4/08

Red light


something is shorted in the circuit, or your subs. unhook the subs first and try it again, if it is still in protect then it is most likely the output transistors.
