Re: blue and white picture
It sounds as though you may have a bad red convergence chip. If it's not the chip, you may have a bad Red CRT ( Picture Tube ). You may want to obtain professional assistance unless you have the proper test equipment to check these items. I hope this has helped in some way.

Hello ksolovy, i understood your Problem with the Sony KP-53V90 53 in. Rear Projection Television,In fact i encountered already that kind of problem you have it now. Check first the color wheel im sure that the blue section of your color wheel was burned and the blue color turn to dark; That's why you have seen dark picture, Re-place color wheel.
Philips has had a big problem with there coolant fluid becoming cloudy. The only way to clear it up is to have the fluid changed. With every projection crt tv there is a layer of cooling fluid between the face of the crt and the lens. This coolant cools the face of the crt. Over time the coolant breaks down and the light coming through gets distorted. The crt's have to be removed from the set to do this.
TV shows large red spot in middle of tv when dark show are on, you can see it more. Now blue spots on upper right side too. Spend way to much on this tv to have these kinds of problems only after 3 yrs.

lg70 nice tv excellent processor just to bad there is no intensity control on color management oh well still better than what the three s are pushing block out the hype lg will be number 1 in a few years haters are starting to come around and well leds coming,
p.s. i dont work for lg just tired of losers bashing stuff because they dont own it. im isf certified those settings are right on the money straighter than a ruler
Heres the best way to set a phillips screen controls. Go into the picture controls and set picture or contrast to roughly 75%, then set brightness to 50% and then set the color level completely off. Then adjust the screen with the 3 color controls untill you recieve the best black and white picture as possible. If you are unable to achieve a good black and white picture change the coolant in the green and blue tubes. But if you can get a good black and white picture stop there then turn your color level back up and the picture should be correct. Let me know if you need further assistance.
They should be adjusted to set voltages. however it is best to shut the color level to the lowest setting then try t balance the screens to achieve the best black and white picture. then turn up your color level. Your brightness level should also be set to 50 % then when you adjust for the best B&W picture. You will have better color and brightness when you reset your color and brightness levels. Hope this helps.
use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
Its a slight possibility that a 2.00 Part called a capacitor could be bad on the screen drive voltage source. But most likly it sounds like the Picture tubes are comming to the end of there life expectancy. If the crts are weak there is a crt rejuvinator that could possibly clean the grids off each color gun. But this is a crap shoot, as sometimes it destroys the tubes. These type of repairs are not for the handi-man or a consumer to do. There are no real user replaceable parts inside so unless your able to solder and know the HI Voltage saftey issues, you should call a pro to assist you in this repair. Good Luck
