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

1 Answer

Blue tint screen in video mode

I have a Sony KP-57HW40 model which since I just moved now shows a blue tinted screen in video 5 & 6 mode. Picture is beautiful when watching cable tv but as soon as I try to play a DVD movie I get a blue tint to the tv. The picture is fine as such, just tinted a faint blue. If I use the video 1 through 4 connections I get a flickering screen as if trying to show color but not quite succeding. This tv was working fine before the move. I would appreciate any help you could give. Thanks in advance.

The screen turns blue after about 2 minutes of turning on the TV


Sony TVs has an Optical Block issue. If there is an issue with the optical block, then there will be green, blue patches or tint on the TV display. Try resetting the TV to the factory settings and try Power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue still persists, then TV may require service. You can contact the Customer relations team and check for the available options. Sony had repaired free of cost for such issues. Hence, contact the customer relations.

Tv comes on for 10 seconds then fades to a green tint then turns completely green for a few seconds than turns off


Hi,
Symptom shows tv got problem with green picture tube that need to be replaced.
Rear projection tv has 3 picture tubes, red-green-blue to make color picture.
Since its an old model so spare parts would hardly be available and local tv repair shop will help you to arrange required part, if they can.
Thanks.

My sony kp-57hw40 has some color issues most of the time the picture has a very blue tint to it. Occassionaly it has a very red tint to it and sometimes it looks ok. What might the problem be?


To correctly repair your tv all three CRT's (picture tubes) would need to be replaced as instructed by SONY service bulletins. Many years ago SONY wanted a better brighter picture and began making some CRT's differently and "better" . But they sadley did not do enough testing . After a few years they realised the mistake and they paid dearly for it. Unfortunatly enough time has passed that the $750.00 or more cost or repair can only come of the consumers pocket . They are good solid tv's when the CRT's get replaced with Panasonic picture tubes.
Sometimes screen control adjustments can done to make the TV work for now but usually a flicker in color remains and it most likely will get bad again .
Hope this explains it for you.

BLUE TINT ON SCREEN ALL THE TIME, COLOR ADJUSTMENTS FINE


Sounds like a bad blue CRT (picture tube) ITs expensive and difficult to replace. CAll a Sony service center for an estimate. but expect to spend $500-700 to replace it.
