From the symptoms you describe, it seems the high voltage flyback autotransformer has failed along with the horizontal amplifier (they are slaved to each other). The sound comes from the flyback unit.

Well, the only way to solve this is to get a technician take a look at the set, I'm afraid. Repairs could cost upto $100 or more, depending upon the number of components that need to be replaced,


It may be worth getting fixed up. If you decide to do so, call around, as shops have different rates and different expertise.

Hope that helps!

    It could also be an issue with the CRT's themselves..

My Sony Wega KP-57WS520 speakers do not sound and Mute is not on rather the variable sound, what can i do?


test the speakers and make sure connected and in menu make sure they are turned on.

The set if in variable may also mute the speakers in the set as that was mostly for a surround sound use.

Sony KV-27HFR TV, no picture no sound; but got HV


The high voltage transformer may be the problem, because it feeds back secondary voltages to different parts of the set, for example is the vertical deflection voltage present at the ic, if memory serves me there should be around 26volts, if it's missing it means the fuse is open or the flyback pin is not generating the voltage.

On my Sony Surround Sound tuner, if I raise the volume up to a certain level (not that loud), I get a flashing sign ''protect'' and the sound to the speakers are cut.


Sony has protection in these receivers for two main reasons.

1 - Checking for DC voltages on the outputs to speakers. Not your particular problem.

2 - Excessive current being drawn from receiver on one or more of the speakers.

Number 2 should be your starting point in finding a solution. Put the volume level on Medium - 35 to 40 on the front panel. Now listen to all you speakers in turn. Any scratching noise will indicate a defective speaker. Remove this speaker from the receiver output and check again if the set goes into protection on high volume.

If you could not find any strange noises on the speakers, remove them one by one and test the set on high volume.

Never - attempt to disengage the protection on this amplifier. The only times we have found the amplifier to be defective with this protection error, it has done so no matter the volume level. Therefore I believe your problem to be a speaker or speakers.

Good luck!

Low sound at high volume


Hi,

THe problem is with the variable resistor present behind your volume control knob, try replacing the volume controls variable resistor, this must work fine... this is a common prblem for all the music equipment that has knob control for the volume....

This resistor can be replaced with your product warranty, contact your seller for the details regarding warranty...No need to woory about this, this is a sommon problem for most of recievers

KV9PT40 sound


You'd need amplified speakers, like used for ipods and such, as the output on the headphone jack is a lower volume.

1210 problem


Those are just standard phonograph player characteristics in my experience. You'll hear a tap on the deck because there's essentially a live mic ( the needle ) physically coupled with the record on the turntable and the rest of the phonograph player even though they try to dampen the coupling of the turntable as much as possible. The rumbling noise at high gain is because the turntables being driven by a motor via gears or a belt and creates some  vibration, wich is transmitted through the turntable and picked up by the transducer ( needle ), low frequency rumble, just like a recording studio on a busy street may pick up from road vibration/ noise.

Audio Out Fixed/Variable


Is your subwoofer amplified or passive?

You clearly understand that you need to use a variable line out to control the subwoofer volume via the TV. As the setup seems reasonable, I'm wondering if the subwoofer is getting a signal, but that it is at line-level and not internally amplified by the subwoofer speaker. Generally, if the subwoofer must be plugged into an AC socket in the wall, it has an internal amplifier and can be fed line-level audio. If it is "passive", it has no amplifier, and it must receive an amplified signal (over speaker wire) from an amplifier (or integrated receiver). TV's don't generally have connections to send out an amplified signal.

If the subwoofer is indeed amplified, then this is obviously not the problem, but it's the first thing to verify given the information provided.

Popping & cracking noises


Is the popping noise coming from the speakers? If it is, lowering the volume to zero does not stop the popping from the speakers, then you have an audio output failure. If the sound is not from the speakers, you probably have a high voltage leak. If this is the case, are you in a moist environment or using the set near a window??
