Hi,
Problem cause is red convergence output chip failure that will be replaced to fix the issue.
If you have experience of electronics stuff repair and can replace parts in circuit board as it requires soldering work with proper tools then can replace convergence output IC in your tv by yourself.
Let me know if you have additional question.
Thanks.

My tv screen when on turns yellow then after a while it will switch back to normal colors what can be wrong with it....


Televisions covered: all Projection with yellow picture, but not Projection TVs with a yellowish tint surrounding objects in a nearly normal picture.

Yellow = red + green
normal picture = red + blue + green (RGB). See illustration.

12_27_2011_5_00_56_am.png

Fig. 1 Additive color mixing in an RGB monitor, or RGB Projection TV.

The circuitry powering your blue output, or the blue light engine itself is starting to fail.

Operating Theory:

The lamp module shines a bright light into the optical unit; there are a series of lens and baffles, and at the top of the light engine, a lens puts the picture into a mirror which is reflected onto the screen; All video and color is processed thru the light engine. Blue most commonly fails first, leaving a yellow picture.

What causes the picture to have a green tint


there are 3 color cathode in your TV red,green,blue cathode.The red and blue cathode might not working in your set that is why you have a green screen. Open the back cover of your TV you can immediately see the 3 cathode lamp at the back. Clean the lamp first using a clean clothe. Power up you tv and see whether the 3 lamps are lit. If lamps do not light up,check the circuit board where this lamp is connected re-solder all the components in this lamp. There is also an individual screen adjustment for the lamps it is located at the front panel and labeled RGB screen...try this first and let me know how it goes..

Sony kdf e50 a60 when TV is turned on picture goes off almost immedately and red light starts blinking in stand by mode.


Red light blinking is an indication of lamp problem. Check and secure tightly the following:
  1. Outside lamp cover
  2. Lamp door
  3. Lamp
If all of the above does not solve the problem, you need to replace the lamp. Let the lamp to cool for 30 minutes after unplugging. Use XL-2400 replacement lamp.
  1. Remove the outside lamp cover.
  2. Remove the lamp door.
  3. Pullout the lamp
  4. Hook a finger through the loop of the lamp handle and pull the handle upwards. Then pull the lamp straight out.
  5. Mount the new lamp securely.
  6. Reattach the lamp door. Turn the knob back to "CLOSE" and secure the cover.
  7. Put the outside lamp cover back in its place.

Samsung HCN4727W Rear Projection TV, green screen, audio works


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,Akai2_bing.gif,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link 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
