Audio problem with Sony Kp-43t75

Ok, there's the problem. I don't have audio on my tv. It was given to us b/c the blue tube needs replaced. It's not the speakers, I've tested them. When the cable isn't plugged into the tv, it makes a weird noise, like it's trying to make the staic noise but can't.what could be wrong and how can I fix it?

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.

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. :)

SONY KP-43T75 HAS ISSUES


well sound like convergence for one and maybe another problem. First look at customer settings and look at convergence and try to realign. Then you can in Standby mode(Power Off) Press Display 5 Vol+ TV power on Remote. Fast. Now do you know what you want to get to? Because changing things here could cause serious problems with your set.

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.
