Question about Sony MHC-ZX70DVD System

2 Answers

Buzzing speakers I've had my Sony MHC-ZX70DVD mini hi-fi for about 5 or 6 years and it's been absolutely fine, until now, when it's started making a buzzing/humming sound through the speakers. It doesn't change with the volume, but does disappear when there's no volume at all. I've tried unplugging everything and even using different speakers, but still they buzz. I've moved the stereo to a different room to make sure it wasn't the plugs or anything like that. Any ideas?

    I have exactly the same problem. Whitesox's solution can't be right because the buzzing is audible even through headphones plugged into the front. It's not the speakers or the connection as far as I can tell. Please help!

    I have the same problem - its not the speaker, as it works fine when both speakers are wired up to the same output. Any ideas?

Have you got cable TV lately? If so, you may have ground loop problem. Easy way is to use isolation transformer to fix it:

It is merely degradation of the connection. Try unconnecting the speakers, cleaning the tips a bit, replacing them in, removing, recleaning, and then replacing a final time. This should get some scoring off of the connection... Aside from this, a new set of speaker wire is the best solution but just let me know what you decide on! Hope this helps!

Hi I'm amit my home theatre Sony mhc zx70dvd system is on what not working display showing push power protector I'm checking all speakers cable every thing is fine so please give me solution


Please confirm that all the speakers are in good working condition. You could un plug all the speakers power on and see if the unit comes on. If it comes on, then one of the speakers or some are damaged. Please plug one by one speaker to see which one has a problem.

Sony Mini - Hi Fi MHC - EC55 won't play CD's. Says it is "Reading" then says "No Disk". I have used lens cleaner and reset factory settings. Any ideas


If you've already tried to clean the lens then with no improvement then its down to the laser having failed.

In some cases these are availble as a replacement part but aren't normally cost effective.

I have a Sony MHC-ZX70DVD unit, when turned on the display shows the radio working but ther is no audio output through to the speakers or headphones at all. Also the CD/DVD player woun't eject and all...


From Sony's Trouble Shooting site:

http://www.kb.sony.com/selfservice/microsites/search.do?cmd=displayKC&externalId=C154211&fes=true&mdl=MHCZX70DVD

If none of this helps, I suggest making sure your wires are correctly connected from your CD player to the speakers. Also, make sure no exposed wires are touching, it should make an audible hiss if they are touching anywhere.
If none of this helps, then I suggest taking it back to where you got it, may just be a dud.

Hope you get it working though,
Cheers.

Not getting high depth of bass sony MHC-RV777d


I wouldn't expect huge bass from those little speakers. Somewhere on there, there's an equiliser, where you 'll probably be able to turn the bass up and down. See if that works. If not, new speakers may help.

How to incrise the bass of sony MHC-RV777d


Is it possible that the speakers are out of phase, where one speaker is moving out, the other is moving in, resulting in zero bass?

Other than checking wires, making sure + on amp is linked to + on speaker, try changing the eq settings, or sit them next to a wall - walls help bass a lot.
