Question about Sony KP-43T70 43" Rear Projection Television

1 Answer

Sony KP-43T75 green ghosting on lt side of image. auto convergence lines it up but 1-2 minutes later .... it's back. do the lenses hvae oil cooling? If so do they need cleaning and refilling with new oil? Perhaps new oil will solve the auto convergence problem( green ghost). Thanks in advance for any help that you send my way. May it return back to you ten fold!

Oi? You mean thermal grease? No thats not the source of the problem in fact I think your problem is not related to the ICs itself. I suspect that you have bad capacitors in the convergence or deflection circuits that have to be replaced? If you are handy at working on electronics I suggest you take a look near the heatsinks(where the ICs are) for capacitors that are bulged or cracked at the tops. If you find any then they will have be replaced with those of exactly the same specs. That should do the trick.

IMAGE GHOSTING


Have you tried the auto converge or flash focus adjustment? This feature allows you to adjust the convergence automatically. If it doesn't work,convergence circuit is faulty. You need to replace the convergence kit, To do this you need some basics on electronics.

Double image, green and yellow ghosts, blurred image - Flash Focus does nto do anything, convergence adjustment does not work at all


That means convergence out ICs are not working, requires replacement.
If you want to replace convergence out ICs, let me know to provide you technical info.

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.

http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html

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.
