One possibility is that the power-on speaker protection delay is stuck on. The most common cause of this is a shorted transistor in one of the power amplifier channels. In that case, you will need to replace the speaker driver transistors in that channel. I don't have service information on your particular model; it may use power amplifier modules rather than individual transistors.

The tricky part is identifying the amplifier power and speaker output terminals to test for this problem. To find a shorted output transistor, you need to measure the resistance between the output of each channel and the plus, then the minus power supply connections. There is a relay between the amplifier output and each speaker terminal on the back; this relay is turned off by the speaker protection circuit, so you can't measure from the speaker terminals. If you have a fried transistor, one of the tests will show a resistance of a fraction of an ohm. A good transistor will have a very high resistance or read open. This will be the case whether you have modular amplifiers or discrete transistors.

If you see a blown fuse, that is a strong indication that you do have a fried transistor. Sometimes the speaker protector circuit shuts down fast enough to save the fuse, but not always.

How do I adjust Left-Right speaker balance on Sony MHC-771 Shelf System? My speakers are mounted the way that I am closer to one of them and I need to compensate for that. Thanks Tom


If you have balance controls for each speaker decrease the vol. to the one closest to you. If you do not have separate balance controls , the one closest to you must be muffled so that the sound will be absorbed and will not sound as loud as the other speaker.

Need a new stereo to work with the old speakers


Any 5.1 surround system will work with this. It is better to be high in impedence than too low.

I have a sony sub model sa-wm20 will it work with this mini system


Read the manual.

You would use the Speaker Terminal hookup option. Your front speakers would attach to the sub's speaker terminals.

I have a Sony mhc gx9000 unit but I don't have da original speakers or wires how can I use it with normal speaker wire. Speakers


I would recommend against it. The system is sold as a package with proprietary connectors for a reason.

http://esupport.sony.com/US/perl/model-documents.pl?mdl=MHCGX9000

You'll notice there are no facilities for balancing the relative volumes in the electronics. After-market speakers of unknown sensitivities would be impossible to match if it could even drive them sufficiently loud.

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.
