    I too Have the 27U-S60 model with a slightly green tinge in the picture. Notably the problem started immediately when I fired-up the set after a little old lady had the TV which was not in use for some time d/t being blind. I would like a set of schamatics for I have some technical experience as a licenses amatuer radio technician/operator. If I can isolate which transistor it is, I feel I can replace it without any problem. Please assist with schamatics and/or voltage charts, etc. e-mail me at: collectiques4u@hotmail.com.

Hi,

Most problems of this nature indicate trouble with the color driver.

Most TVs have three (3) color drives for red, blue and green. it would appear that your particular unit developed a fault with the green drive. Normally these are transistors (but there are IC versions). Further, they are often on a squarish small PCB right at the rear of the neck of the CRT. Often also, they are with a heatsink.

Corrective measure would require replacement. Doing this would require that you be familiar with electronic components and circuitry, use of a DVM and a soldering iron. Should you be uncomfortable doing this, you may then need the services of a professional TV technician.

Hope this be of help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

The 1.5k resistor in the load circuit of the green output transistor is open. This is on a small pc board plugged into the CRT. -- Al

I just need to adjust the resolution on this TV. NO ONE at RCA could seem to help me. Thank you.


hi,
did u mean to adjust the picture setting then go for the following
1 press menu on the remote
2. using down arrow select picture quality and press ok. available options in picture quality and its use is listed below. you can use it according to your preference.

Basic Picture Control- Displays the five slider controls for adjusting

the way the picture looks.

Contrast Adjusts the difference between the light and dark areas

of the picture.

Color Adjusts- the richness of the color

Tint Adjusts the balance between the red and green levels

Black Level Adjusts the brightness of the picture

.

Sharpness Adjusts the crispness of edges in the picture.


When exiting this menu, the Save Personal Picture Preset choice list will

appear. You can choose either Yes or No. If you save the settings as a

Personal Picture Preset, the TV will store the settings so you can reselect

them easily if someone changes the settings.

Picture Presets Displays- a choice list that lets you select one of three

preset picture settings: Bright Lighting, Normal Lighting, Soft Lighting

or Personal Picture Preset. Choose the setting that is best for your

viewing environment.

Auto Color Displays- a choice list that lets you turn on the feature that

automatically corrects the color of the picture. (This is especially useful

for tracking realistic flesh tone colors as you switch from channel to

channel.) Choose On or Off, depending on your preference.

Color Warmth Displays- a choice list that lets you set one of three

automatic color adjustments: Cool for a more blue palette of picture

colors; Normal; and Warm for a more red palette of picture colors. The

warm setting corresponds to the National Television Standards

Committee (NTSC) standard of 6500?K.

Video Noise Reduction Displays- a choice list that lets you turn on the

feature that automatically reduces noise from the picture. Audiovariable

enables the TV to automatically adjust noise reduction level;

off turns off noise reduction feature; on-fixed sets a fixed level of noise

reduction.

My color seems to be more green than should be and I have tried to reset the color with no help


You have a focus/screen control box Find it and adjust the R/G/B screen drives When you first start Go to Menu turn Color off then with a mirror adjust the picture as close as you can to a black and white picture R/G/B screen drives, the little control box you are looking for will have 3 controls on top for focus and 3 controls under them for screen drives to each tube red,green,blue after you have adjusted to a black and white picture then go back and turn color on.

Red , Green And Blue.


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.

Green tint I can't seem to fix


Hopefully someone on here has a manual and can tell you exactly where the tint controls are. Also need to try adjusting the color level, turn it clear down so you have a black and white picture.
Is the picture still green over the screen with the color control
set clear down to black and white? If it does, you might
have an issue with the green gun going out or problem in the
circuitry to it.


By the way, the best way to adjust the picture settings on a
tv are to first turn the color control clear down, then adjust
brightness and contrast for best black and white picture, then
bring up the color level to where it should be and adjust the
tint for best red/green ratio.
