I had the same problem until a radio install tech told me to hook up the blue and white stripe wire. This turns on the audio amp.It works great now.

Hi Jrb10dl

A quick way to tell is to measure the voltage on each speaker wire. If it is a High Power unit, you should have approx 6-7 volts on each speaker wire. If not, then the chip is definatly blown.
Chances are high with no sound that it is blown, unless it is a Pioneer, they have voltage sense circuits that will mute audio if all power supply rails are not present. Change it and see is the best approach. Any questions you may have I am happy to answer. I have worked on this sort of gear for years. A FixYa rating would be awesome

    Hi Roadster

    Pioneer units need all power supply rails present before the internal circuitry of the unit alloows power to be turned on to the output stages. Check that you have ALL required power connections to the unit. mem, access power and constant power.

your sound ic is blown if you can get hold of an amplifier connect it to your deck and if you get sound out of it then your sound ic is surely blown and will need replacing

How to fix a logitech surround sound system


if there is no light on the control, check the mains fuse on the back of the woofer box, if blown, you may have an amplifier ic (tda7294) blown (there are 6 on the big board), replace the ic, if still no sound, mute may be blocked in on position, on small side board there is a transistor (2n4401) connected to a white wire going to the big board, replace the transistor (you may use a bc337)

My tv has no sound when turned on and I've checked all possible menu solutions, mute issues, etc. What else can I do?


unplug from the mains and open up the cover to check for the possible open wires in the speakers. measure the speaker windings to ensure its not open or not shorting.
there could also be a possibilty of a sound ic blown due to excessive supply voltage. in the sound output region you`ll find sound output ic ``TDA`` which should be replaced to restore back the sound

I gave my son a leapster explorer about a month now and it's volume just stopped working and it wont hear anything.


Hello,
there are three basic reasons why the leapster explorer won't bring out sound.
1. Defective speaker
The speaker of your leapster explorer maybe defective, this can make it not bring out any sound. Disassemble the leapster explorer, check the speaker part, test the speaker with a AA battery. If you hear any sound using the battery, then it means there is nothing wrong with the speaker.
2. Loose wire connection
Disassemble the leapster explorer, check the wires connecting the speaker to the board. Check for any wire cut, or loose connection which can cause the speaker not to bring out sound. . 3. Sound IC/Card/Board
If non of the above is the cause of the problem, then it means the leapster explorer is having a defective sound ic/board/card. There is an IC on the board of the leapster explorer which is responsible for sound. If this ic has a shot, there won't be any sound. If this be the cause, I think it's high time to took the leapster explorer to a repairman because this requires skill.
I hope the above is clear. If not, please let me know for further assistance.
Regards.

TV has no sound


Hello

You haven's specified nothing about the picture. Picture is Ok and there is no sound I thinks and posts this solution

Either your TVs speaker or its sound out put ic has damaged. To check it and conifrm you just do this first. There is a stero headphone socket on the front panel of your TV. Insert a headphone pin inot it and listen whether there is sound output come ffrom it or not. If there is sound output from the headphone socket, and not from the speaker, be sure taht the speaker is out.
If there is no sound output from the headphone socet, wither your TVs sound output ic is damaged or it doesn't get proper voltage to go on. It is very easy to locate this IC, as speaker wire goes directly to this section. Just follow the speaker wire and locate the IC, usually screwed on to a metal heatsink. Check its input voltage. If there is no voltage to that IC, check the track associated with that pin. If there is voltages and still not works. first resolder all the pins of that IC by applying a little more solder, whout shorting the adjecent terminals. If this does not helps, replace that IC with same type and number. OK.

if the loose speaker wire touched ground it may have blown the output ic. also make sure you have no other loose or shorted wires as this will cause the output not to work.

You may have "Blown" you speaker Amp. It may have fuses, but if that case, ONLY one channel would have blown? I think it is time to get a "Quote" from a reliable service center/man

I recently bought a 1994 Camaro with a Kenwood KRC 953 stereo in it. The radio display is working but no sound at all is coming out of the speakers. What is the problem?


Yo most likely have a bad speaker or the amplifier IC inside the radio is bad. More often than not, it is the amp IC.

first double check that you have all speakers connected right and that you don't have a speaker wire that may have an exposed area that could be shorting against the car chassis.

You can check the speakers by disconnecting them one at a time and see if the sound returns to the remaining speakers that are still connected. After checking one speaker, re-connect it and try another.

If the sound returns after dis-connecting one speaker, that speaker is your problem.

If none of this helps, you will need to get it serviced. If you are skilled with soldering and can dis-assemble and then properly re-assemble a radio, this is a very easy fix and I can look up the part number for you of the amp IC. it is also right on the IC itself. If the amp IC is blown up badly, you will see burn markes on it and sometimes a piece of it can be blown right off of it. In that case you will not be able to read the part number.

Normal repair cost for this type of a problem run between $80 and $120 at most shops, depending on the shops rates.

This is a very high end cassette player and in it's day cost about $400 back in 1997 when it came out. But todays car stereos are nearly as good built, and cost much less.

You can get a good car stereo with CD for about $150, cheap ones for $100.

Let me know if you need any further help, and if you found that this information was helpful a good rating would really be appreciated.

Thanks and have a great day,
Dave

No audio


Have you tried to check the audio as it is coming off of the detector right before it enters the first audio amplifier? you can check this with an oscilloscope and then trace the signal through the stages of amplification the signal should get bigger. I think that you may have blown the final audio output amp. and what you are gearing is pre-driver audio through a leakage path. This is just a hypothesis, but I have seen this happen before.
