    Hi again, I forgot to say that this green and blue on TV is shaky and some times it becomes some lines in different color patterns ( parallel lines ). When the picture comes it is excellent in quality. The problem is each time I want to turn on the TV, I have to sit down for 30 to 60 minutes and play with remote, and if I am lucky the pictures come on then. Please help me with this issue.

    Thanks

If convergence is intermittent, then most likely poor solder connection on convergence board. This is not a simple repair. Accessing the board, removing it, identifying the poor connections and soldering, then re-installing is delicate work.

If you are in Calgary, call me.

Tip

What to do when you only have Green on a CRT Projection TV.


If you have a picture, but only in green on a 3 crt projection TV, I would try turning up the drive for the red and blue guns. They have probably changed over time and red and blue have lost drive and need a boost. Green makes up 70 percent of the picture compared to red and blue so the drive would not have to drop much to lose red and green but still have green. Keep in mind that this does mean that the CRTs are dying and may not have too much time left.

To turn up the drives first remove the back cover on the bottom half of the machine. Be very careful as you will have to work on this unit live. Do not touch anything other than what I tell you and keep one hand in your pocket whenever possible.

First look at the space above the main circuit board. Somewhere across the beam supporting the CRTs you will see a square box with 6 controls (shafts). You can locate the box if you follow the wires from the flyback to the box. The flyback is located on the power board and produces the high voltage. It will have 4 large red rubber wires coming out of it. Three go to the focus divider block (the box in question) then they go on to the crts (red, green, blue).

Once you locate the focus divider look at it closely. The focus controls are on top and the drives are on the bottom. They should be marked red, green and blue. You want to turn up the red and blue. Tune a picture with as much black as possible. While watching it turn up the red until you see a red tint or streak then turn down until it just disappears. Do the same with the blue. You may want to touch up the green also for good color balance.

If the set is working OK and the CRTs have enough drive left, your picture should look normal.

Thanks for using FixYa.

Hi I have a rca hd52w59. the top half of the


Projection sets have two very common problems.

The first common problem is 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. 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 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...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*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
