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

3 Answers

Picture has a green shade

We have a Toshiba tv and when we turned it on the picture has a yellow-green tint to the whole picture. We tried to correct it using the tint and other features but it still stays the same. We have also unplugged the tv from the wall hoping it would reset itself. Any suggestions? I recently had a focus block replaced on my Sony KP-57HW40.After getting it back the picture had a green tint to it. I called my repair guy and he said it would adjust itself and it did for about a month and a half. Now I turn it on and a good picture lasts for 5-45 minutes and then it goes to the green tint. I called the repairman back and he said me problem was unrelated to the focus block replacement.PLEASE HELP ME.

    There wasn't any type of magnet nearby nor did I see a degauss option.Tell me more about the convergence IC and were would I locate it or the degauss option. I will also inquire about the gun brightness possibility with the my tv repairman. thanx

    When I hit the main menu button on the remote,the color scheme for the selections i.e. color,brightness and sharpness etc.(each word is different color) they are as they should be, but the show that I'm viewing behind the menu still has that green tint.lt seems like the signal as it comes through my satellite box is getting from the true colors to the green hue intermittently

    Talked to the repairman that replaced my focus block about the green tint and he says that now I need a light engine replace that will cost me another $500. This sux!!! the tv is only 6 yrs old and I'm about to be charged half the amt. I paid for the tv. I need to know where the light engine is and I'll replace it myself!!!

This problem is called the gauss' effect. Its caused by the prescence of magnetic materials near the tv. If anything please move them away from the tv. If your tv has the degauss option just degauss it when it happens. IF none of this works then its probably a problem with your convergence IC. Please let us know so that we can assist you further.

    Also if your focus block has gun brightness and colour focus then it might be possible that its a problem with the focus block.

    Its not the problem with your satellite box. Your focus block is the culprit! go return it to where you got it from, and demand for a new piece.

Have 57 " Toshiba projection TV there is way too much red in picture


TV has 3 CRTs, red, blue, green. Its possible that you have a bad blue or green crt. If that were the case the red would be prevalent and the pic would be reddish. The tv has a picture "level" adjustment that if done correctly could get it looking correct. Its probably best to have a tech. do it since you can make it worse if you do not know what you are doing, also there are high voltages present. Good luck

Here is something that may help from the toshiba.com website under your model number television. Q. Why are people on my screen green?
Models: 32HL17, 37HL17, 42HL17, 42HL167, 47HL167, 52HL167, 42HL167, 42LX177, 46LX177, 52LX177, 57LX177
REF:FAQLCD00107
If the problem is not the connections, try adjusting the tint on your television. A high tint setting will usually create a green
image on the screen where as a low tint will create a more red hue. In order to access your television's tint:
1. Press the “MENU” button on your remote control and use the LEFT or RIGHT arrow keys and select the
VIDEO menu.
2. Then use the UP and DOWN arrow keys to highlight PICTURE SETTINGS and press the "ENTER" button on
your remote.
3. Next use the UP and DOWN arrow keys to highlight TINT then use the LEFT or RIGHT arrow keys to adjust the
TINT. If the picture is too green the tint will need to be lowered.
4. Once you have adjusted the tint to your liking, use the DOWN arrow key to highlight DONE and press ENTER. The toshiba customer service telephone number is : 1-800-631-3811. I hope this helps you with your problem.

Picture has a green shade


Sounds like your red picture tube is not emitting enough brightness to balance the colors. A temporary solution could be to slightly increase the screen voltage of the red CRT to give a good black and white picture when the color control is turned all the way down. If the set has not been serviced in the last 5 years or so, and you're not ready for a new HDTV set, it may be worthwhile to get a technican to look at it and clean the dust off the lenses and mirror and evaluate whether a picture tube rejuvination might work along with the gray scale tracking adjustments.

Toshiba 32AF41 Power up Problem and Green Screen


My first inclination would be to check the picture tube, especially if the set is over 7 years old. If it is not that, then anything from bad solder connections to capacitors or a defective IC could be the cause. If it's over 10 years old, replace it. No use flogging a dead horse.
