Power protect tends to mean the main power amp chip has "blown" and needs to be replaced. It only costs about 20 dollars (10GBP). If you are handy with a soldering iron it is easy to do (after you get the thing to bits !) It is the big black thing on the big heatsink inside. The Sony part number is STK442 - 130. Seems a waste to throw the whole thing away for the sake of 10 pounds !. Hope this helps. Nik Howell (nh@totalise.co.uk)

Need a good 500 watt cd player not sure what to buy


Before you go off on a wattage hunt you should learn what that means.

Search the web for subjects such as "amplifier wattage vs speaker wattage" for starts.

Don't buy into what manuafacturers CLAIM for wattage if it ADDS all the channels together and FAILS to specify a bandwidth and an acceptably low distortion figure. REPUTABLE makers specify watts per channel, all channels driven at no more than X distortion (typically well under .1%) and, at minimum, across the audio bandwidth or 20Hz - 20kHz.

Any garbage cheapo amp (meaning most shelf systems or all-in-one packages) can put out a lot of dirty power which will strain THEM and possibly kill your speakers. CLEAN POWER is what you want.

Dosome reading and search the web for whatever you are considering, and add the word 'scam' to the search. Get opinions from actual owners. There are a lot of unscrupulous people out there selling garbage to people on the streets.

My rca rs 2657 cd changer is stuck. door will not open. any ideas how to correct?


If you hit the open button and you hear a sound like a motor running than it is most likely a belt or connection that physically opens the tray. You'll have to take it apart, locate the cd player and check from there. If no sound of a motor running when the button is pushed then the motor is probably bad.

Converter for my sony grand wega 60" to work in the U.K.


The specifications for this set list the power consumption at 250 watts so allow for a little extra and go with a 500 watt converter. Also, make sure the converter will change the UK's 50Hz power to the 60 Hz power required for the set. To be exact, the converter must change the UK's 230 volt 50 hertz power to 120 volts (100 will do) 60 hertz. Do NOT attempt to run the TV on 50 hertz power as it is likely you will damage the set

Protection displayed and shuts off


The protect message indicates that the output amp section has a problem. Normally this requires the replacement of the output transistors or the output amp pac. Expect the repair cost to be about $20-$60 for parts plus the local labor rate.
