double check the settings of your AV,channels setup and cable box.
im sure that your guests did not physically mess up your tv and speakers right? so just double check the input and output wirings for everything there on your tv.
one probable cause maybe the remote has a switch feature which you can control avr, tv, receivers a.k.a. universal. check also the sound setup for the tv as it may have been changed to stereo or mono and surround mix...

Re: no sound with cable tv- AM/FM works ok
First, check all the connections to the receiver.. Make sure everything is plugged in where it should be.. Also make sure, that when you are on TV/CABLE that the surround sound is selected and that "headphones" is not.. Also check any other modes that may have been changed, (IE digital input, 5.1 channel, etc...)

go through the input modes its one of them leave it each mode on for 30 seconds what output do you have for audio on the blueray. It can also be setting for audio from blueray was turned off swich to fiberoptec
Generally you will connect the Digital audio or optical audio cable from TV to the input of Receiver. Then using the remote control of Receiver you will program the source for digital audio or optical audio as TV. I am assuming the speakers on the receiver are already connected and working. All you do is then turn on TV and turn on Receiver and select TV on Receiver. The TV audio will play through the receiver. Make sure the TV sound is in Mute.
I think there is a switching problem in the surround receiver. I would take the receiver to a qualified servicer. There is nothing user serviceable in the unit. Question .Why are you using optical output from ps3. I recommend you connect all you a/v devised to the tv. Then connect the opt out of tv to receiver. that way what ever you are viewing will send audio via opt out of tv to receiver. that way you do not have to switch input on receiver. Hope this helps.
Ok...sorry it took me so long to get back to you...Check the back of you tv and look for RCA jacks for audio and video out...There should be a yellow one for video..a white one for audio left(L) and a red one for audio righ(R)...you may not need the yellow one...now look for any inputs on the rear panel of the surround sound system...They can be marked (AUX)...they will work..once all of these are located...you will need an RCA patch cable long enough to reach from the tv to the surround sound receiver...once done...turn on the tv and the surround sound.With the remote from the surround sound remote...switch between the input sources..maybe (AUX) until you hear your tv sound come through...then you adjust the sound as needed...Assuming the DVD is built in to the surround sound system...your DVD sound will come back when you play DVD's...All connections and cables are color coded so you should have no problem connecting everything....Good luck....let me know how it goes,,,,I hope this was helpful....PEACE.....
Do you have set-top-box or antenna-cable directly to TV? You have connected TV with received via HDMI, but that won't work in this direction - TV has HDMI INput only, not output. You can use HDMI to connect HDMI-out on DVD player for example to HDMI-in on receiver and HDMI-out of receiver to HDMI-in on TV. But to get sound from TV to the receiver, use spdif optical or coax cable if TV supports that - this way you will get surround sound. But also your connection via analog white/red RCA plugs should work, but only for stereo sound.
Can I assume the calibration procedure also didn't work for the Front left channel? (It's not a "surround" if it's in the front). Switch the receiver to Stereo mode to eliminate any DSP actions. Tune an FM station to eliminate any external device or cable issues. What do you hear from the two Front speakers?
OK? Select a DSP surround mode. Check all modes. What happens?
If the channel goes dead using some or all DSP modes there's probably something wrong with the processor. If they all work...
Isolate the source that exhibits the problem.
It was a bad left channel cable somewhere, wasn't it?
