Nothing comes on. The red LED does come on when in standby mode. When the unit is turned on the led goes out but nothing happens. No other light comes on. No sound comes out. I have unplugged and turned...

Generally speaking, an amp protects itself from heat, shorts and overloads by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections as a root cause for intermittent shutdown.

Speakers buzz with no sound

Is this only with CD, only with THAT CD, or with nothing in particular selected or playing?

Check all connections for tightness as bad cable shield connections will let emitted noise into the system. Ditto for signal or speaker cables routed near power cables, TV's, other electrical sources.

Sometimews reversing the AC power cord polarity can resolve buzz/hum.

Lip sync playing ordinary tv

you need to have a sound speed equalization higher frequencies travel slow,
if you can buy a AV/RF CONVERTER the problem can finish
AV be connected to devices and RF to tv
this can over come that problem

Fornt speakers does not have any sound.

remove the front speakers cables from the rear-remove surround speaker cables from the rear and put them in the place of front speaker-run a music if you get good sound the problem in your front speakers(speaker or its cable)-if you got nothing you will have a problem in your system itself and need to fix in service center.

'stereo' speaker problems

Yer man there a load of **** i've got 2 x DV290's one for the back of my studio & one powering the front,your lucky you only had 2 **** speakers i had 4 lol.
but there is light at the end of the woofer,they have to be wired together its as if one makes the other one work,so you put GRAY & BLUE in you get BASS or hum ,you put BLACK & RED in you get HIGH or top end you put all four in you get nice mixture.
I've also had it another by mistake & it worked, i put the + & - side by side instead of top & bottom so it was RED / GRAY & BLACK / BLUE if you know what i mean.then cut the plugs off the surrounds & wired them in aswell & it's all good in de hood.
oh a tip before i go,get some rubber legs off the bottom of something or the casters off an old chair or stool & GET THEM SLAPPED BETWEEN THE AMP & THE SOUND PROCESSOR for ventilation coz Fu*"*k me they don't half get hot man!
good luck pal....later

After a while the system starts crackling and eventually sound deteriorates to thundering in speakers

Hi, I have exactly the same prob and I belive that it is in the amp module?! I am going to take mine in for repair as my other sony HT amp has just give up the ghost, (STR-DE435), it has a protector prob and is probably not worth repairing, although it is a great amp. If anyone knows the solution to this prob it would be great to hear it!!!
