Ok well my system is hooked up and it is all right. but now all of a sudden my amp wont come on at all, i know it is getting power because i can take the power cable and hook it into the remote terminal on the amp and the power terminal on the amp and it will turn on. It will not turn on though with just the power cable in the power terminal on the amp...if anyone has any advice i would appreciate it thanks...

Re: amp wont turn on
Sounds like a fuse issue in the power from the amp - the remote circuit could be and probably is completely independent. haven't been able to find confirmation on this, but if you are confident to take the cover off then check (probably)around the area where the power terminals are there may be some fuses.
Hope this helps, ask again if not :)

If you remove the signal cable from the amplifier while the Sub is switched on (turned down about half way) you should hear a thump sound. If you do that proves that your sub is working and you need to look at your Yamaha. Perhaps the sub channel has been disabled in the logic settings. Check the speaker configuration pages. If all looks well reset your amp to factory settings and try again. I have had a logic glitch which was fixed in this way.
Yaou will have to take a look at Power Output Stages, Q34/Q35, MJE2955/MJE3055 power output transistors, as well as the other amp with B817/D1047 power devices, first one drives the woofer and the other the hf driver, let me know further.
NEVER USE MAXIMUM VOLUME FOR TROUBLESHOOTING. The errant switch or control that you eventually find and flip will suddenly release the amp's full power and you'll destroy your speakers. If a signal isn't audible at 1/2 volume, for all intents and purposes it's not there. Look for a misplaced Mute or Tape Monitor control or Multichannel Analog Input selected.
There is a good chance that a common control may have developed a high-resistance or 'dead' spot through idleness and is causing your symptom. Turn the POWER OFF and operate every control throughout its range a number of times, especially rarely-used ones like Tape Monitors and the Mute control.
Turn the volume to something reasonable and see if that helped.
I believe you should take time and check your connection.
please use the right cable for your sub. you need the right cable
to boost the sub. Check radio shark or Sam Ask for better sub cable.The better one don't come with your system.
First of all take a headphones and connect it to the TV and listen the sound.If it is OK the problem is or the cable or the amp.You probably have two RCA connectors on the cable red and white or black for input of the amp.Connect the cable to the tv again and change places of the RCAs (red to white on the amp and white to red).If cracling is now on the left speaker buy a new cable but if its still on the right you have problem with the amp.And you are right if everything is OK it shouldn't be cracling.I hope that this will help you
The 'Subwoofer' output on your receiver is used to connect to a powered subwoofer with a built in amplifier. Your KLH speakers use what is called a 'passive' subwoofer, it gets its power from the receiver and then passes the higher frequencies to the left and right front speakers after taking out the low frequencies for the subwoofer. A speaker system with a passive subwoofer is good for casual listening, but a powered subwoofer is required for really hearing low frequencies and rumble in movies. The KLH speakers you have were highly rated in their time for their price. The four satellite speakers and center channel speaker have very good sound compared to the little 'midget' surround sound speakers most people buy today.
Here's how you hook them up:
- The left and right front channels from your receiver terminals should go to the terminals on the subwoofer marked 'From Amplifier'
- Your left and right front speakers are then connected to the subwoofer terminals marked 'To Speakers', they do not connect directly to your receiver.
- Your center speaker is connected to your receiver terminals marked 'Center'
- Your rear speakers are connected to your receiver terminals marked 'Surround'
That should get you up and running. If the bass isn't good enough with the passive subwoofer, you can get a decent powered subwoofer like the Velodyne VX-10 for about $150 and 'kick it up a notch'. Good luck and enjoy....
take amp to a workbench, have a test speaker in hand, touch the speaker wires to each channel to see if all channels work. take each speaker to the amp and temporarily hook one at a time to see if any speaker is bad. if you eliminate the hardware, you know it's the wires in between.
