    Hello all, thankyou all so much!! I really appreciate the "helping hand" your team has given me, I had no idea where to begin looking for the problem. I checked and cleaned all the wires (took the sticky duct tape off), checked connections, changed plugins. I found the white and orange plugs were in the wrong places on the back of the tv due to some moving of furniture around so I could get my floors redone.

    Once I could hear sound out of the 'extra" set of speakers I knew I was on the right track.



    Again, thankyou very much and I am saving this site for future, hope you stay on the airwaves :)

    Thanks

Protect usually means a speaker wire problem. remove all connections and redo them making nice tight twists in the connections the spliced end should be no more than 1/4 inch long. make sure to do this for all speakers as well as on the back of the unit.

    it could be one little strand of copper so just dont do a quick look see. Just remove all the wires on speakers as well as on the back of the unit. Then post comment to see if that helped or not. then i can help you further.

    another diagnosis is to make sure if unit is not defective by removing all speaker wires from back of unit. yes i did say all speaker wires. Now try to turn volume up and see if it is internal problem. If you get a protect this way this means the unit is in need of service or replacing

  • Chuck Feb 23, 2009

    did you try my last diagnosis by removing all wires from back of unit? and then see if it still happens? if i helped fix it how bout a fix ya....thanks and good luck any other questions try charles_farrah@comcast.net it is easier

  • Chuck Feb 24, 2009

    so what is the verdict? if it works ok when all speaker wires disconnected and doesnt go to protect (turning volume up) you can then attach one speaker at a time and see which one gives you the protect mode. there could be a malfunction in one speaker. or like i said earlier that if it still goes to protect with all wires off then it is internal and something more major is wrong.

How to reset my sony mhc-gs100??? it keep saying power protect...


Your stereo went into protect mode to prevent complete failure of the amplifier inside that radio. Most of the time this happens from playing the stereo real loud for a real long time and it overheats. Most of the time disconnecting the receiver/stereo and letting it cool all the way down or at least 5 minutes and then reconnecting it to the power source will reset the protection mode. You want to make sure you are keeping the radio cool. Don't stack anything on top of it and try keeping a small fan blowing on it to expedite the heat out from the unit. Also turning it down every now and then to let everything cool down a bit will help prevent it from going into protection mode as well.

It keeps shutting of and the power light just flashes if there is too much bass? what do i do? the volume is low to begin with


Hello, the protect circuit is likely detecting a damaged speaker or speaker wire.Check the unit with one speaker at a time connected, or if you have an ohmmeter measure each speaker they should read approximately 8 ohms.When you connect a speaker thats bad the unit is designed to shut down and flash protect.

Problem with turning my system on....


whan a unit goes into protect, it could be a bad speaker, shorted speaker wires. or the most common fault is a blown audio o/p ic in the unit. due to being compact units they are more difficult to work on than the full size unit. the part typically runs between $25.00 to $75.00 usd. if you are good with working on small places and are good with soldering give it a try. the ic will be on a heatsink. good luck.
