I have a 27" Toshiba television, I'm having problem with the sound. I've changed the sound output but nothing happen. Please help.

Here are some possible locations where to look to :
( Since I have no model for your TV or additional details which you have

a) switching IC ( these IC switches the TV to Audio Video In)

b) muting circuits ( there could be one )

c) Check the audio out coming from the Jungle IC (also unknown)

d) check the supply lines of the audio IC (could be +12V, typical)

e) Check the headphones out (if available)

If there is an audio Out, connect an external amp to test.

If audio is present , check again for solder joints to main amp.

Use these as a guide in troubleshooting :

Computer Speakers

Your input is the Jungle IC, search on line for datasheet about it.

same with your Switching IC and Audio IC.

On some audio IC, volume control is included on it.

Let us know what you find or needs further assistance.

No audio on sanyo ds31520 after replacing vertical IC.

Replacing vertical output IC won't poise this type of problem. Check the voltages at the audio output section.

No sound

First check whether sound control has been muted or not. If muted, as you know, there will be no output from the speakers. If not muted, and still no sound, there are two possibilities. The first one is of speaker, and the second one is with the audio output IC inside the circuit
Check its speaker first. you can check the speakers with the help of a multimeter, of with a torch cell. If speakers are found OK, and still there is no sound output, the audio output IC is faulty and shoul be replaced with same number . The number of the audio output IC for your tV is [TA8265K]. This IC can be located at the main board of your tV. If you have eneough knoledge and tools to do the job, you can replace it at home.
If you want anymore assistance from me, inform me by FixYa comment box. I've all the repair details about your tV with me. OK.

I have an rca ctc186/7 series tv and it has no sound. We tried cleaning it, hooking other speakers to it and hooking up a dvd player and still no sound.


The audio output Ic inside your tv has damaged, or it doesn't get proper voltage. You just open your TV, and locate the audio output Ic. It can be located by following the speaker wires. Usually it will be screwed onto a heatsink. Check the input voltage with the help of a multi meter, af it is there, the Ic is damaged. Replacing it will solve the problem. If there is no voltage, follow the supply track and find out the opened circuit point. Usually a small value resistor, say 0.01Ohms in value, will be connected in series with the power supply to Ic. If it gets opened, there will be no supply to Ic, resulting no sound. If the audio outpu Ic get short this resistor will open. So keep in mind that, if this resistor is opened, there may be a short inside the output Ic, or come capacitors fitted with this supply line, after the reistor. Check the also for any short. keep a keen look at the solderings fo the leges of this output Ic. Some loose, or bad solderings also may be there. Anyway, your TVs audio output section is faulty. Find the reason and rectify it. If audio Ic is found defective, desolder it out from the board, and replace it with a same type and number. Ok

RCA G35831AT 35" TV

The G35831AT uses the CTC179 series chassis. When you touched the wires to the speaker jacks you probably somehow managed to short out the audio output IC, which would have sent up some smoke. When the set is turned on, the computer senses that the audio output IC is shorted and shuts the set down. The audio output IC should be replaced and all other circuits checked by a qualified tech familiar with the 179 chassis.
