Question about Technics SCEH790 CD Shelf System

Sound cuts out

When watching DVDs/ music the sound randomly cuts out. This mainly happens when the sound is pretty loud. Ive talked to a few people about it and they say that it sounds like the amp has blown. Is their anyway to fix this or would I have to buy a new amp for it. If so how much do they roughly cost. The system seems to work fine but through a film the sound just goes dead. Any help would be appreciated. Thanks

If you listen to cd's and the sound dos'ent cut out then it cant be the amp. It could be the audio cables are intermittant between the amp and the dvd playerr or they are loose or corroded a little. or ppossible the input your using is going bad on the stereo sytem but I wouldnt think that the whole system was blown if the radio and the cd plays normal.. check out the causes I listed and let us know if you need more assistance\..:)

Sounds like a Sony, if it uses a lamp the green cast is most likely the optical light engine in the set---major part.

When i watch dvds,the background noise is loud


Go to your set up menu, navigate to speaker set up and check your sound levels to front, center, and rear channels. Adjust as needed to fit the room. My Sony has a test tone option which sends a signal (at levels selected) to each speaker to check sound level and if speaker is connected and in right place.

Speakers cut out randomly


The only thing i can think of is the amount of power surging into the speakers is too great and they are cutting of to avoid blowing out. I have a similar issue with my surround sound if i turn it up too loud.

Speakers sound as if have background interferance


Hi Naomi. I am not sure of your model, but you probably have a build in mic. If so, open your sound properties from your task bar, Click on File - Advanced Properties. You should now see a "Mic" volume control. Mute this control and see if this stops the sound.

If this does not work, locate the manufacturer of your sound card and visit their website to download newer drivers, if available. If this also does not work, you will need to return the product to the retailer to reinstall a clean version of windows. Many times files become easily corrupt in the installation of audio codecs, drivers, etc. Hope this helps.

Overloading


hi mate, ive had the same problem before with this amp. i bought it new aout 6 years ago and bought another new one about 1 year ago, new, for £70!

on the first amp there was a problem with the surround sound aspect, it kept overloading when turned up even a fraction, it would tick 4 times and power off. Eventually the surround sound stopped working all together and whenever selected made a VERY VERY loud hissing/crashing noise through all my speakers, blowing one of them, SO BE VERY CAREFULL.

when that happened i assumed was broken so bought another one, and had same overload trouble when i got a new speaker package.

Im pretty dam sure it was the ohmage ratings being different on 2 of the surround sound speakers that srewed the 1st one, so id suggest you check theyre all ok, as well as the speaker watt-age.

what are the specs on all your speakers (ohms and watts RMS)??

do you listen to LOUD music through the 5.1 option??

hope this helps, if all else fails buy a new one mate, theyre so cheap. go into panasonic shops and see if they have any left.

If DIGITAL sign blink, this mean DSP board is defective. It will cut the sound on the AMP section. DSp is maybe defective.
