When the wires touched, the output transistors overloaded before the fuse had a chance to blow. The outputs need to be changed. It is possible that the driver stage for the final outputs is bad also, but there is no way to know that without removing the bad outputs. Figure on $25-$45 in parts for this repair.

    The output transistors will be the 3-legged parts attached to the heatsink in the rear. If you have not repaired these units before, be careful as just replacing the transistors might not be enough and could damage the new parts if additional checks are not made.

How do I hook up the sub woofer to my home stereo system


You don't say what make or type either of the appliances are, so I can only answer in general terms.
First look at the back of your stereo system and see if there is a dedicated subwoofer output. If there is you should be able to find the correct lead between the two units by looking at both the connections. If the subwoofer is a powered one. IE with a mains plug on it, you have to plug it into the mains before it will work at all. The connection points also then need to be hooked up to the amp. If it's not a powered subwoofer then your main left and right channels speaker wires need to be split into using the subwoofer terminals provided. Another set of terminals on the sub, then lead to the main speakers.
Lastly if it has a dedicated subwoofer output, then the amp might have a setting that turns this on or off. So you might need to switch it on.

Hook up new blueray thru old home theater system


Yes you can. If you have more than 1 HDMI sources and your old system only has 1 HDMI in, you may want to invest in an HDMI switch. They are inexpensive (under $20 on Amazon) and let you choose 4 HDMI sources to feed your system. The audio is embedded in HDMI and you may have to select the choices (surround versus stereo) when you play the disc.

I wanted to know if there is a way to hook up the sound from a Panasonic DMP-BD655P-K Blu-Ray player to my existing Yamaha DVX C310SW home theater system. I know I can hook the Blu Ray directly to the TV...


Yes this can be done. You have several options for audio hookup. Stereo 2-channel (white and red) RCA cables, digital audio (optical or coaxial) or HDMI. Your home theater must have the inputs available such as optical, coaxial etc. Typically the stereo 2-channel RCA is the simple way. Just connect from the Bluray audio outputs to the Home theater inputs (white and red) for stereo sound. Select the input on the home theater. For Dolby Digital 5.1 use optical digital audio cable (black port) or coaxial (orange RCA port) from Bluray to similar home theater input.

Sony BDV-370 DVD/5.1 theater hooked to Sony Bravia TV and cable box. No sound comes from rear or center speakers with HD cable.


Three things can cause this:
1) not all HD is recorded in surround sound. You can very well watch an HD program that just has Left/Right stereo audio. Tombstone on bluray is even only in Dolby 2.0
2) wrong connection is used. If you only use red/white analog stereo cables you will only get sound out of the left/right mains.
3) setting on the cable box is set to stereo and not surround. Changing this varies by cable box manufacturer.

How can I hook an iPod touch to a coby dvd968?


It has a USB port that you may be able to us with your iPod's sync cable (I'm not familiar with this Coby model) but you can always hook an iPod to any stereo or home theater using a mini jack to RCA stereo audio cable, just plug one end into the headphone jack on the iPod and the red/white cables go into an audio input in back (or front) of stereo or home theater. Good Luck.

Can I plug just one subwoofer into my Yamaha EMX88S? What kind of sub do I need to get for it? Do I need to have 2 subs plugged in for it to sound right? Do I daisy chain the subs with the A15 speakers I...


it is not reccomended to daisy chain passive subs with main speakers, because there is no crossover unit involved. you want a sub to have a crossover frequency around 100hz, so that only frequencies lower than this go through the subs, and not in the main speakers.

you could get away with 1 sub plugged into the mono output on the front, subs dont have to be stereo. you would need a self popwered sub, or an additional amplifier+crossover for passive subs. your best bet would to be to get a powered sub and hook it up to the front panel mono out. powered subs usually already have the crossover built--in.

In the monitor section on the 2488 console (upper right) make sure your monitoring source is set to 'stereo'. Then make sure your 'monitor level' control is turned up. The 'stereo' fader (sub mix fader on the MKI, stereo fader on the MKII).
