My sony KV-G21PD1 sounds are not working


Hello
Either your TVs internal speaker or its sound output Ic has damaged. You can make sure about which part is damaged through the following sugession.
Just place your ear, very close to the TVs speaker side, and switch on your TV with its front panel power switch, not by the remote control. If you can hear a 'thumb' sound or 'HUM' sound, you can make sure that the speaker is ok. If you hear a 'HUM' sound as describe above, make sure that its sound output Ic has damaged. If the sound output Ic has damaged, sometimes you may not hear any sound at all too.
Connect the TVs audio out RCA scoet to an amplifier, if you have, and try to get the sound through it. If there is sound through an external device, make sure once again that the internal sound output Ic has damaged. Speaker can be checked by a torch cell, connecting its terminals to the two leads of the speaker, with two pieces of wire, just intermittent touch, you can make sure that it is ok or not.
To replace the sound output Ic, you must open your TV, and locate the sound output section inside it. It is easy, to do, just follow the speaker wire, and find it from which point from the main board it orginates. Somewhere near to it, you can loact this Ic.
Before replacing the Ic, just measure whethere there is voltage comes to its supply terminal or not. If there is voltage, and no sound at all, replace the Ic with same type and number without any doubt.
If there is no voltage comes to the input pin of that Ic, check the track leading voltage to that point, and find whether there is any resistor has opend or not. Ok
If you need any further assistance, contact me through Fixya.
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.


Hello

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

The sub-woofer amplifier is probably blown. This is a separate circuit from the other channels. It will need to be repaired. It is likely a bad transistor or open resistor that over heated.

My RCA RS2664 won't stay on. As soon as I power on, it says "bye" end turns back off. Help Please!


This is a common problem with this model.  There is something wrong with the power circuit.  Open this puppy up and test the circuits.
Your first mistake was buying a RCA you cheap ***.  Get you a Sony, Panasonic, or Pioneer.  Less stress and more fun.
Take the thing back for a refund if your within 30 days.  Have RCA tech support fix it if your within 1 year. Pawn this thing off on e-bay or a garage sale or Goodwill if your out of warranty.
