    as per description you have an issue with the CRT socket that solder on the part may have cracks (this causes the "too much green"), What you are saying indicates that the blue gun is intermitten, and the solder joints on the CRT socket itself (blue cathode) or the blue output transistor have probably cracked loose. once again, all you have to do is resolder it in place to ensure that the CRT sockets are mounted, and that will solve your problem,



    The CRT socket is located behind it near the audio or video input.



    Good luck, hope you get this one working in no time.

Have a Sanyo big screen tv but need need to adjust the color, to yellow!


Need to know if older set with picture tubes---turn color off--if yellow screen you have a loss of blue of some sort--red and green will give you a yellow screen. If set has the 3 picture tubes look inside in the lens to see if all 3 have a image---little or no blue means a problem there.

AOC PD4264 Screen fault


Extremely blue color temperature that cannot be adjusted; some false-contouring artifacts in dark scenes; no picture-in-picture; limited connectivity with just one DVI and no HDMI inputs.
If use as a TV monitor:
The number of colors you can display is controlled by the video card installed in your computer. In order to display more than 16 colors, the proper video card driver must be installed. Contact your computer or video card manufacturer to obtain the latest driver from them.
If you are watching standard-definition or Cable/RF signal on an HDTV, the picture may appear to be of poor quality. This is because the TV is designed for viewing HD or at least digital content. Your best bet would be to upgrade to a Dish Network HD receiver and connect it to the TV with an HDMI cable. Similarly inputting analog signal to TV from your DVD player will not appear to be of great quality. A newer DVD player would most likely have component video output which would look much better. To get even greater quality, an upconverting DVD player connected with an HDMI cable would look the best. You could also upgrade to a Blu-ray disc player, which is capable of playing HD Blu-ray discs as well as DVD's at higher resolution. A less expensive choice could also be a streaming media box. Hierarchy of inputs for good picture quality:

My Toshiba cinema series HD separates the red & blue color.


The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Projection TV sets have two very common problems listed below.

Problem #1) Convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu.

The blue color sags in regular tv but is fine in hd


Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.

77ea520.jpg
f0900cb.jpg
Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

2c07611.pngSolution #1

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

My componet/av only shows black and white on my vizio vp422


The 37" Vizio I just bought has a very confusing feature where the same input can be used as either the Y channel of the component or the full video channel for composite. If you plug a component source into the TV and then select the composite input ("AV" on the remote), you will see a black and white version of the full component signal (makes sense as the Y channel is just the luminance component). As sad as it is, I was stumped by this for a while until I happened to hit "COMP" and got full color. FWIW, the manual warns about this, but it really doesn't emphasize the point. I wonder how many returns they get because of this.

My phillips model 60pp920217f has a horrible picture...no green to the color


The green CRT coolant has congealed thats whats giving you the green halos. Change the coolant in the green and blue and your set will be fine. red is never affected so the red coolant should be fine.

Mitsubish hd 1080I wt 46809


Check settings first to make sure no one changed anything out of the ordinary. Are the shadows that of a color or darkened shadow? It could be out of convergence, which can be corrected in the menu - or it could be low quality video cables to. Also, if there is no green, does a white color show up when you're in a menu mode (Red+Blue+Green = White Image)? If so, then the green picture tube is working and it's just a color adjustment, otherwise you may have to invest in a new green picture tube.
