When I play the TV through my Denon 500SD system everything works ok for about 2 minutes then a hiss starts in the left speaker and gradually gets louder
Thanks for the suggestion but this hissing only happens when I play a TV signal through the system. It all works perfectly well when I simply use it to play DVDs. Is your solution to replace the cables still worth doing?

Hissing sound caused by input section RCA cables defected grounding maybe loosed or the RCA cables are defected already replaced it with new RCA cables so hissing sound is gone.

You don't say how "TV audio" is entering the system.
My guess is you're using analog audio Out from the TV into an analog input on the Denon. One channel failing would probably be the Left Channel cable failing or not seated.
I always recommend bypassing the TV audio entirely if the programming comes from somewhere other than its own antenna, as TV audio electronics add nothing good to the process.
If you're using cable box, sat box, game, whatever, ITS audio is best sent directly to your Denon's specialized audio hardware - digitally, if possible, to preserve multichannel possibilities.
You could also run standard analog audio from the cable box to the TV analog Audio IN if you just want to watch news and weather on TV speakers without the Denon involved.
Sounds like a speaker wire is shorting against either another speaker wire or something metallic. Check your speaker wires to make sure they're not shorting (touching). If that doesn't work, I'd take it to a repair facility. Good luck!
You could try the optical route. You should be able to use the analog RCA audio outputs of the TV to the analog TV or VCR audio inputs of the receiver as well. Select the appropriate input on the receiver and you should have TV audio.
Check your speaker wires on zone 2 and look inthe manual for speaker configurations with zone 2. you may have a speaker conflict. If you still have an issue, post a comment with your speaker setup and I'll help some more. Hope this helps
the problem may be two fold
1 the optical pickup assembly's lens may be dirty and needs to be cleaned (donot use any liquid to clean the lens just a soft cotton swab will do)
2 the optical pickup assembly has failed and can no longer read discs (if the laser or sensors inside the optic fail it is "blind" and can not "see" the disc)
start with the cleaning.
VERY nice system! But, it practically needs a cooling system of its own! So, the very FIRST thing to check is to make certain there is plenty of OPEN SPACE around the receiver.
SECOND: Make certain ALL of your speakers have an IMPEDENCE of 8 OHMS. (Denon says 6 ohms is okay; I still recommend 8.) Virtually all speakers of even modest quality will include this specification on a label on the back of the speaker.
You CANNOT run more than (2) TWO speakers with 4 OHMs impedence on ANY amplifier (technical discussion too long!)
[NOTE: Your Denon's internal overload protection system is designed to do precisely what it is doing, to prevent permanent damage. In general, shutting-down, then re-powering the system after several minutes usually resets it. However, if there is a problem, this will continue, AND YOU RUN THE RISK OF DOING SERIOUS DAMAGE TO THE MACHINE!]
Before you take this monster in for service, there is one more "test": check for shorted and/or mis-connected/disconnected speaker cables/wires. With as many as 22 speakers connected, this could take some time. But it MIGHT be worth it.
1) Visually inspect connections at the receiver and speakers first. You might find something obvious!
2) If everything looks okay, then disconnect ALL of the speakers; and reconnect and test them one at a time (at relatively low volume.) For example, reconnect the left front speaker, test the system; THEN add the left front, test the system,and so on, ADDING one more speaker each time - FIRST MAKING SURE EACH OF THEM HAS AN IMPEDENCE OF AT LEAST 8 OHMS! IF there is a short (or bad speaker) this will help isolate it.
Denon is a very respected brand, and will give you a LIFETIME of service. Hopefully one of these simple fixes will work for you. GOOD LUCK!
My best guess from what you have said is that you may have some speaker wiring shorting (or bad speaker) or else you have a bad output transistor or a poor solder connection in the output amp area. If it isn't the wiring/speaker problem but the other then you will most likely need to see a repair guy to get it fixed. Hope this helps.
