Question about Samsung HC-P4241W 42" Rear Projection HDTV-Ready Television

1 Answer

Blue haze around image, yellow streak

I have a HC-P4241W I purchased 2 1\2 years ago. 6 months ago, I could no longer adjust the green vertical line in the convergence mode. As a result my screen is bowed from top to bottom like ) ( this. I figure its the IC's STK394- 250. Thats not the main problem. Lately I noticed that I am getting yellow streaks starting at the bottom and going up about 6 inches , going across the screen. Not solid all across, just a few streaks. Someone told me to check the collant, the blue is a pale brown color. Any thoughts on how to fix it?

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. 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, Zenith, and others. You can get a convergenece repair kit wiith 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 - makes a chirping sound.
Problem #2

I have a blue streak going horizontally through the top portion of the screen with shadows behind it. It also looks like the screen is "darker" or more yellow to it.

Your loosing you blue CRT. High voltage adjustment may cure. Horizonal like is called retrace line. Lack of high voltage allows this line to be visible

Blue wide streaks in my 42" Sony TV model KDFE42A10.

I have the same TV and the same problem and it's also just over 2 years old (bought it June 2006) when the problem started. Every day, I saw the blue streak cover more of the tv, now 6 months later, it has all turned to green and the entire tv has a green tint. It looks like I am watching tv in murky green water.
I am lucky that I purchased the additional warranty on the tv and finally got around to calling them. I hate to tell you this, but they told me that the optical light has gone up and they are replacing the tv.

I would suggest getting another optical block from the repair man. Apparently even some replacement blocks have had issues...

HX-P4241W appears yellow. Left and Right of screen are yellow

Yellow is the lack of blue. It can happen when you are running your contrast - which is your overall light level - too high.

Try turning down your contrast. On CRT tech, contrast should always be run at half what the factory allows as full, on the user controls. Full up is what calibrators call Torch Mode, and is NOT the way to get performance to be in the linear operating range of CRT tech.

If your sides are more yellow than your middle, your set may need lenstriping. Mild yellow on the sides is not uncommon, and usually not noticed. But heavy yellow on the sides would indicate that the blue image needs work on white field uniformity.

Yellow is the lack of blue, in CRT tech.
