Question about Sharp CD-C3900 CD Shelf System

1 Answer

Radio stopped working

I turned on my radio after taking it to a freinds house and turned it up to 26 and it shut off and all it says is protection mode. I've had the radio a while now and never experienced this before. I no longer have the guide that came with it. I've tried unplugging it for quite some time and it still does it. How can I fix this?

Possible that output IC may be blown when set was overdriven. The 'Protect" error usually appears when the audio output IC is defective.

The volume wont go higher than 12 on my Jensen Mcd5110 Marine Radio/am/fm/Cd receiver W/Detachable face, how can I fix it to go all the way up to 26 plus?


take off the bottom cover ,find the volume switch on the outside then find it on the inside.Now get some WD-40 and spray the control on the inside with a very,very light squirt of WD - 40. Let it set for a while then try it.It should work.

I have a trc447cb radio, it kept blowing fuses, please help thanks...


This radio has been hooked up backwards. CB radios cannot be hooked up backwards or it will destroy it. However this is hope.

Because they can be damaged this way, there are polarity protection diodes in the radio that will blow if the radio is hooked up backwards, before it can hurt anything in the radio.

They are usually N1004 diodes. Is a big black diode that has a white stripe. And if it is blown, it will most likely be Black and burnt.

Open the radio, and look near the power section of the radio. It will be in the back near where the power cord plugs into it.

Look for a burnt black diode. That is the protection diode.

Get an N1004 or better from radio shack, and remove the burnt one, and put the new one in, making sure to put it in with the white strip on the same side as the original.

Once you have finished. Make sure the polarity is correct. Then hook up the radio, and turn it on. Should work fine.

If you want to validate that it is the correct diode, if you pull on leg out of the board, and turn on the radio, it will turn on. When the diode blows, it prevent the power from getting to the board, if you take it out, it will let it through. CAUTION. The radio will work again if you just remove the burn diode without replacing it. But if you hook it backwards again, it will be toast, and as good a door stop.

My jvc hx-d7 radio is turned on in 2 seconds it shuts down to protect mode how do i take protect off ?


You can't. The main amplifier module will probably have a channel blown. The unit is detecting this and tripping into protect mode to stop further damage occurring. Needs to go to a repair place. sorry. ps If you get sound briefly before it trips off then it may just be a speaker wire shorting out! worth checking

Radio shuts off at volume of 16 or more


Maybe a protection component cutting in.
If you have speakers that are too powerful for the radio it may shut down to protect the amplifier from overdriving the speakers. That produces too much heat in the amp chips/transistors and they either have a overload cut out protection circuit or they burn out.
Even if the speakers are the stock fitted ones the wattage could be bigger than the amp in the radio can handle.
There's probably no way of knowing how powerful the speakers in the truck are but you could try the radio with another set.
Max 50 Watts for that radio. If you don't have the manual for it, it's available here:

My stereo is flashing the work "PROTECT" across the front


In a Kenwood deck, "PROTECT" usually means that one of the speaker output wires is shorted. The first thing to do is pull the deck and inspect the wiring at the back, making sure there aren't any pinched or exposed wires. If a speaker wire is pinched against the deck chassis, or bare wire is touching dash metal, it can cause your problem. If you don't see anything obvious, disconnect all speaker wires from the deck, then turn it on. If it still flashes "protect", then you have a defect in the unit. If not, then re-connect the speakers one at a time until you find the one that causes it to go into Protect mode. Usually if you don't find a pinched or shorted wire behind the radio, the problem can be found at the speaker itself. This is especially common if you've installed after-market speakers; if a speaker terminal connection has come loose and is now touching the speaker basket or mounting surface, it will shut down the deck.

When i turn my radio up all the way my speakers cut out and then come back on


Yes it is probably too powerful for those speakers. Or the speakers could be defective.
