Question about Sony KP-57HW40 57" Rear Projection Television

1 Answer

Sony KP-57HW40 57 in. Green Circles

When I turn the TV off or on there is a large Green Ball in the middle of the screen. When the TV is running there are several large green circles on the screen that are very noticable when the picture is showing something dark like a night scene. I have taken the back off the TV and cleaned the CRT lenses and the Mirror and vaccumed all the PC boards which had some dust build up.. It is still there!!!!!!! I already had to have this set repaired about 3 months after I puchased it because everything was green when you were watching it. This thing has a great picture when its right but its not very reliable & it doesn't have have a very long life.

MY SONY KP41T35 PIC FLASHES ON OFF ON OFF AND GREEN PROJECTOR IS ON BUT NOT SENDING PIC JUST GREEN LIGHT


Sony PTVs do get bad CRTs, to confirm you can pull the front cover and tap on the middle CRT (green) neck with a plastic handle if the green screen flashes back to normal or brighter and causes the TV to shutdown then the CRT is bad. sometimes you can make it stay working for awhile, but eventually the CRT will need replacing. if this doesn't help you can turn the bottom middle control counter clockwise to lower the green .
hope this helps

hi, you`ve lost your convergence ic`s, unless your very proficient at solder work I`d advise you call a tech, will require removing 2 large IC`s and possibly a few small support parts, resistors, chemical fuses etc. Every place is a little different but runs approx. 300.00 at my shop, gl, video-tek

Sony 43 inch rear projection tv, I have lined up the convergence but still seeing red and green around edge of the tv on the images, seems fine in the middle of the screen though.


Always start at the vary center of the screen with Green. Position Red over Green, then Blue over what now will look yellow. If all is perfect except the outside, you will need to adjust "Mid-Size" until the middle is just as far off as the outside lines. Then adjust the main "Size" adustments to match. Go very slow or you can make a mess of it.

Green flashes then tv turns off


or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

Sounds to me like its your green tube. Kind of expensive replacement, but easy.
