Re: LED light dont come on!!! Pioneer audio receiver...
Do you mean that the display that show the audio source or mode doesn't turn on? Try shining a bright flashlight at the display and see if you can read it. If you can, then the backlight light bulbs have died.
Replacing it will be a pain but you may find a usable replacement at Radio Shack. Just measure the voltage that goes to the bulbs and find one with similar ratings. They are probably 12v lamps.You will need to remove the display from the front panel of the amp and desolder the old lamps. Getting at the bulbs is the hardest part.

That would depend on where the (unidentified) TV audio comes FROM. If it's the analog output of the TV, the TV has a volume control hidden somwhere in a menu. Or you could select the FIXED output so its volume control has no effect on external use of the audio.
If the TV audio comes from a Cable Box analog output, IT might also have a control that varies the volume out. Disable it.
Lip Sync issues are the nature of the beast. The TV has to process the digital video bitstream a lot more than the receiver has to process the audio so the result can be a gradual lagging of the video behind the sound... http://en.wikipedia.org/wiki/Lip_sync Some receivers have a sound delay control which you can use to try to sync them up. You didn't name yours so one does not know. I don't think this unit has that function. Look in the manual.

You do not mention if this is a Pioneer VSX type receiver or if it is a Stereo receiver. Assuming the first, you need to enable the Sub-out output. The Owners manual will show you how. Then you should connect from the Sub-out using a good quality RCA type sub specific if possible cable to your Klipsch Sub. Play with all the levels until you are satisfied. It will take some time to set up properly.
First try checking all the speaker cables and speakers. Listen to them all make sure they are all playing when playing softly, if not there could be a short in the speaker cable/speaker causing it to protect. Another way, disconnect them all and connect one at a time, test it etc, when the fault re-occurs, in that line.
If thats not it then sorry will have to go to a tech as it sounds like protection is kicking in or PSU fault
This is a common problem with a few of the Pioneer of that era (VSX-3300, 3700, etc). A secundary power supply line is faulty and it prevents your display from working. It is not an easy DIY, but a local tech should be able to fix. It is not always the same exact cause, as there are a couple transistors, a zener diode and a cap that can fail.
You can continue to use it without any detrimental effects on the unit, and can guess the settings.
Heatsinks on mosfets are probably not connected, or broke connection. If you are not trained in electronics dont go poking and proding around in there, a capacitor can easily kill you. If you have some knowledge open it up and see if you see and burnt components etc. You may just need new heatsink grease etc. Does it have a fan that stopped working? If a piece is visually fried take the unit to your local electronic repair shop and see if they can solder in a new part if available. depending on the price of the amp, it would be ebetter to go spend money on a new one.
