Re: audio problem

Audio issue may be the cable. The green picture sounds like a convergence problem. Try to adjust the convergence in the menu and if that does not fix it you may need to get a repair facility out to take a look at the convergence amps.

No sound on my sony kp-51w40

A few things to check first:

Make sure speakers in set are not turned off or sound muted.

Make sure if using a cable box sound is not turned all the way down.

Lastly, check if you get sound when you hook a dvd etc to one of the rear audio/video inputs on back of the set.

If none of this resolves your problem you have an audio circuit problem.

This is very rare in this model.

If model number is correct there is a way with the original sony remote to do a reset of the set.

Let me know what you find and if you have questions comment here.

Sony KP-43T75 color repair

This link has the instructions on how to fix this problem and other similar problems. You have nothing to lose, so I recommend that you try it.

This works with the two other colors, blue and green also. Not all models of Sony Projection TVs have the red, green, and blue pots in the same order as the picture that is listed on this link, so you may want to google search for your model's service manual. The service manual can also help you be able to remove the cover for your particular model of TV. I was able to find the service manual for my model, and sure enough, the order of the pots are reversed on mine, so I would have been adjusting the wrong color. Read all of the comments on this link too, because you can find other helpful tips and may even find someone with the same model of TV as you that gives more specific instructions for your model.

You may also find your model's service manual here:
I hope this helps you!

Fare well. :)

I have a sony KP-51HW40 51 in rear projection we have a picture no sound. Do you have any clue what this could be? Thank you!

There are several easy things it could be.  The speakers could have been turned off in your audio settings or if you hooked up a cable or satellite box, dvd, vcr, game box or other piece of equipment that had it's own lines in for sound that could be part of the problem. Sometimes if you use picture in picture or the index function you can accidentally swap input and the primary input no longer has sound going to it.  I'd definitely recommend trying all the simple solutions first.

Audio problem with Sony Kp-43t75

Check multiple sources, this will confirm it the problem is before or after your audio switch. If the problem is on all inputs, you may need an new audio IC. It is the heatsinked IC right next to where the speakers plug into the A board.

No audio

9 times out of 10 a TV like that which has no audio is fine and the audio settings are not right or it is a cable box / satellite receiver problem. If you are using cable then connect the cable directly to the TV, tune in an active channel and set the volume about half way. If you do not hear any sound then, using the remote, go into the menu, scroll to the audio page and make sure the speakers are not set to OFF and also make sure the audio is not set to SAP. If you have checked all that and everything is set correctly and you still have no audio, then your audio output IC is probably bad or cracked and should be resoldered or replaced by a qualified tech.

Sounds like a conergence circuit failure, probably a couple of AMPs and a few discreet components. Probably 250-300 repair

Speaker Off/On

If I am reading your symptoms correctly, it sounds like you are getting audio to your surround sound receiver, but not your TV speakers? If that is the case, I would be checking for a defective audio output IC and possibly an IC Protector fuse connected to it.
