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..

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.

Just bought a Sony KV-27ts20 second hand. Great


There might be another solution beside the trash can. You see often with audio problem the fault is the audio output i.c that is gone. Also in the tv menu you may have speaker on/off, make sure they are on. If it still doesn`t work then you may want to try the audio out connectors at the back of the set,there may be sound there. What you`ll need is and audio system with aux/cd/tape input and a rca/phono stereo cable. Just connect the tv out to any free input and turn up the volume .
By the way the tv audio out may be variable(option in the audio menu) which means that any amplified speakers(computer speakers) could be used as long as you have rca connectors on the end of it.
Hope this will help. Good luck

Go to your tv menu, and make sure that your fixed audio output is selected not variable. Variable will make not work, with the television volume is turn down. When you hook the speakers, make certain that it is on a fixed audio out, not variable, as well.

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??

Sony 36' trinitron no picture but sound


I don't think it's your picture tube, but it may be a problem in your high voltage power supply. If there is no anode voltage then there is no raster (light from the screen) or picture. If it is your high voltage section the you may want to think about taking the set to a shop because of the danger of electrical shock.

Volume control doesn't work on the enternal speaker


On some sets that have audio output jacks, the level of the audio output on the RCA jacks is fixed, and it does not change with the TV's volume control. On some sets, such as Sony, you can choose fixed or variable output. I have also seen some sets that have both fixed and variable RCA jacks on the back. With variable audio out, the audio level at the audio output jacks follows the TV's volume control. If you go into the TV's menu and navigate to the audio page, look for fixed or variable output options. If you have the owner's manual, read the section on audio output. If variable output is not an option on your model, then the level is constant and the volume will have to be adjusted with the stereo's volume control.

Picture keeps turning off with volume still on.


you have a problem with one of the following circuits: video amplifier, ABL (automatic brightness limiting) circuit, crt circuit or in horizontal deflection and high voltage circuits. probably a leaky component that when it get warm it it looses its function or maybe a cold solder. but if u do not know these stuffs better have it check by a qualified service technician.
