Sony hcd vx55


Hello. I downloaded the manual for the Sony system with the model number MHC-VX55. It seems that the part you are asking about is not a speaker system, but a preamplifie/power amplifier with integrated inputs from CD/Video, tape and tuner. The speakers that connect to the HCD-VX55 are a three way passive design with a nominal impedance of 6 ohms and model number SS-VX55. To answer your question I will assume that you meant you would like to connect the MHC-VX55 system to your computer for playing back audio tracks from your computer. Yes, you can do this. Your Sony system is equipped with an input labelled MD/Video (audio) With a sensitivity of 450 mV, this will (not ideally) the output from your computer headphone jack (if a laptop) or, even better you may have a desktop with an audio output at line level. You will need a simple audio connector with a 3.5 mm stereo plug on each end (very common and readily available for a few dollars. Be careful when setting up that you have your source turned down low and the input on your Sony machine about half way. You will find the sweet settings so that you get good sound without distortion. If you get distortion your source level is too high. Hope this helps. Cheers, Don.

Hello, I have a prob with my Sony HCD-RV999D I just bought it from a friend, I plug the outlet everything is normal, I press the power button, the system turns on normally, but after 3 second it turns...


The reason this happens is because it takes about 3 to 5 sec. for the output circuit relay to kick in after power up, im sure at this point is when your receiver shuts off and flashes red. You have a bad output Transister its shorted to ground and the sony's protection circuit kicks in and shuts it down. Unless you are a electronic Tech. you will have to take it in to be repaired its going to be about 120 dollars to repair. Now im assuming your speakers are ok, if you have them hooked up when you do this try disconnecting them and try to power up if it does you have a shorted speaker, but normally Sony just displays overload protection on the display. Im sure you have a shorted Trans. sorry for the bad news good luck.

Message displays push power protect, pls help


That is the common symptom of the defected STK-IC in power amp.section that busted already or just a lost contact.First try to resolder the pins of STK-IC if its works! if not that is the time you replace it, so it works normal again.

Hope it may helps you...

If there is no power at all, then try bypassing surge protector, check power cable, and check if power cord is fused.

If unit has power but does not start, then it is on protection.

Protect mode will kicking whenever a fault is detected.

Causes that can start protect mode are:

Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.

Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.

Internal fault.
Internal fault is the natural cause for protect mode. If all the above did not work, then the problem is a blown component or an internal fault. In this case the unit must be taken apart , tested and repaired by an experienced person.
If the unit is less than one year old, or if you want to get service, call Sony at the phone number listed on the product documentation.

Regards.

Sony SA-VA 100 won't turn on


You can try a factory reset.

Push and hold down Dolby NR, stop and disc 7 buttons, then push power.

Otherwise it looks like $60 to $100 repair bill. These are not the most repair freindly units.

Good Luck.

"Protect" error - HTZ110


Home Theater System Is Displaying "Protection" spacer.gif As soon as the unit is turned on, the word "PROTECTION" will flash on the front panel of the unit and SHUT OFF. This error message usually indicates that the fan in the back of the unit is not on.

The PROTECTION feature automatically shuts down the unit to avoid further damage. The unit will need service if this error message is displayed.
