Question about Sony Grand WEGA KDF-55XS955 55" Rear Projection HDTV

Missing color in picture - red

I noticed that the colors were looking sort of fadded. Reading the manual it say's one of the solutions would be to replace the bulb. I did, and now the colors may be brighter but we are still missing the color red as in before we replced the bulb. What is supposed to be red looks brown and green's look yellow, etc. I set the colors back to original seetings, no help. Played around with the hue and color bars, no help. What am I missing???

My Vizio 32 inch HDTV picture colors are all off. I have tried to adjust the tint/colors but the overall picture colors are all off. It is as if some of the primary colors are missing.


Maybe if you are using component input wires, one is not inserted fully. Set color to max and put tint in the center, then flip channels and look for known solid colors items of red, blue and green. You can see when one is missing, as a mixed color will just look odd, but a true r,b or g will just not be there so to speak. Hopefully is might just be a feed wire in, but be careful, as too much pressure on insertion can crack a solder joint inside the set.

No sound on play back using camcorder on technika tv


Looks like you are using Component cables. There are five cables. The first three cables are Green,Blue and Red. These are the ones that are molded next to each other and are the Video signal cables. The other two cables are Red and White and they are the audio cables.
First to correctly hook up these cables you need to Connect (Match) Color for Color. (Green to Green, Blue to Blue, and Red to Red. To tell if you have correctly connected the Video cables is to look at the screen. If the picture looks ok (Normal with no colors missing then you have connected the video cables correctly). If you see a missing color meaning red, then switch the Red cables. The picture should be ok now. The remaining two cables are the Red and White cables. The "Red cable" is for the "Right" audio input and the "White" cable is for the "Left" audio Input". If all is connected correctly then you should have a good picture and Left and Right audio.

How to adjust color on sk-32h570d


This is from the MANUAL
www.westinghousedigital.com/pdf/197_User_Manual.pdf

PAGE 27

A-1 Settings
Use the Settings sub-menu options to manually adjust the display quality. Use the ◄/► keys to adjust the
option level.
Adjust the luminance level.
Adjust the brightness to darkness ratio.
Adjust the balance of the red, green, and blue colors in the display.
Adjust the color intensity.
Adjust the sharpness or softness of the display.
Adjust the brightness level of the screen backlight.


AND this is from the troubleshooting procedures in the manual

PAGE 64


Wrong, abnormal or missing colors

・ If any colors (red, green or blue) are missing, check the video cable to make sure it is securely connected. Loose or broken pins in the cable connector could cause an improper connection.
・ Press and select Picture | Settings to adjust the Hue and Saturation settings. You can also select
Picture | Advanced to adjust the Color Temperature settings.
・Connect the TV to another computer and check if the problem is with the computer screen.


Other than that there is no mention of color adjustment

Colors shadowing eachother, adj convergence, but will not save.


Sounds like your convergence IC chips have failed. You can buy the parts from various suppliers or you can just get a complete repair kit from www.TvRepairKits.com

Colors are off after auto adjust


I seem to have found the solution (and the cause, perhaps?) for this problem!

I was having the EXACT same problem with a monitor I'm repairing for a friend. The capacitors on the power supply board were blown (CapXon capacitors, who'd've guessed), which was keeping it from powering up. After replacing the capacitors, the screen worked beautifully. But it had this weird yellow tint!

The strange part was that pure colors - red, green, blue - all appeared perfectly OK on screen. Curiously, the menus would show in the proper colors, except for one: the manual color adjustment menu, which illustrated "Blue" as a sort of off-green in the icon. Auto-Adjust would always fix the colors for a split second, then go back to yellow. Reset didn't fix it. Color reset didn't either. So, exactly the same problem as above.

The solution I found was hidden within the main menu itself, a sort of "easter egg". <b>Hold the Menu button down while pressing Power, and hold it down until the screen, and menu, appear</b>. There will now be a hidden selection, "Auto Color", printed in a red-on-black font at the bottom of the menu. Use the +/- buttons to access it, and press Menu. Voila! PERFECT COLOR! Perhaps this menu was accessed by accident, and calibrated to an incorrect color key. But now my picture works great, and the setting lasts through Auto-Adjusts and Resets!

Hope this helps some people, it sure saved my ****! ;)

Red colour missing


- A bended color pin at the VGA connector. (If pin one is bend then there would be no red color)

- A defective VGA signal cable. If the internal wires were broken then there would be missing colors. You can check if the signal cable is good or bad by doing a continuity test using a multimeter.

- Dry joints in the CRT board such as in the CRT socket pins, video pre amp and driver IC and even at the connector pins. In fact this problem contributed about 80% of Monitor color problems. Applying fresh solder would usually solve the color problem.

- A defective IC either in the Video Pre-amp or Video Driver IC.

- Faulty components in the CRT board. It could be a shorted driver transistor or even electrolytic capacitors that the ESR reading had shot up!

- A bad CRT socket. Sometimes decayed glue could cause the internal pins rusted and thus affecting the colors. Replacing only the CRT socket would definitely solve the problem.

- A weak or a defective picture tube (CRT tube). Yes, I do came across one of the electron gun (most probably the cathode materials had used up) in the tube faulty caused a missing color in the screen. There’s no way to repair this type of problem-the only way is to replace the CRT tube.

- In the newer type of Monitor, color setting is save in the EEPROM IC . Thus, if the EEprom data is corrupted, you would also get a missing color! The only way to repair it is to reprogram the IC or use a soft jig to tune it back the color setting.

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.
