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

1 Answer

The Blue Color Convergence is highly distorted & will not adjust.

The set powered down by it's self and then came back on with all colors misalligned and double images. In the convergence mode I can adjust both the Red and Green but not Blue. When I try to adjust the Blue color lines it has no effect; the lines will not move in any direction. Also, the blue lines (in the convergence mode) are highly distorted as you progress from left to right on the screen. The lines dip down from the top and up from the bottom starting about half way accross screen. The HC-P4241W is approx four years old. Your help is appreciated as funds are very limited.

    I can' believe I was told to "turn the TV off for 5 minutes then turn it back on"? That has to be an automated response right?

    Your comment "the 2 output ic's stk392-110 which should be replaced" is understood. Should they be replaced with the same type IC's (392-110) or the newer STK392-180 chip which seems to handle heat a little better. I just don't know if they would be a good replacement IC for this set. Also, what circuit board are the STK IC's located on and can that board be removed completely from the TV set? Thanks...Danny

    HI

    It just like a restart..

    First we want to check it like this

    Turn off for five minutes and then turn on

    while u turn on the tv, again u get the problem means..

    then only we want check the circuit board ok...

    u just do it and then tell me what is happening

    thank you

    hi

    After turn on the tv the problem continues means..

    do this if ur well in technical means do this other wise better go the service man..

    The trouble is the 2 output ic's stk392-110 which should be replaced..

    All three Color Amps are within these ic's for
    both horizontal and vertical convergence.

    Sometimes a resistor or two
    will burn out as well because of the short in these ic's.

    Be sure to be
    extrremely careful unsoldering and soldering and use good heat sink
    compound and fasten securely to the heatsink metal.

    Manual convergence
    calibration may be necessary after the ic's are replaced.

    First try
    Touch Focus after the ic's have been Properly replaced.

    Thank you


  • Thafa Nov 13, 2008

    Hi

    Better u replace with the same type IC's..

    Safety is important Danny...

    Check the resistors and other components with the multimeter..

    Thank you..

How can I fix a distorted picture?


it was convergence problem, tried first with adjustment at the set up menu. select color adjustment then adjust the red and blue to make have white balance. if can not resolved with adjustment it could be a bad convergence ic or an open change value resistor ( high resistance) near the ic.

I have some distored blue color across the screen


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
*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

We have Phillips 55 in rear projection TV and just set our color convergence back to factory settings but we still have an awful picture. Any suggestions? All objects have multiple halo bars on them....


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

Common Symptoms include....
  • 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.
  • TV shuts off after powering on - TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

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

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution

This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

Distorted image and color


sounds like the convergence ICs have failed. Will the red and blue move in all 4 directions when you try to adjust the convergence? If not the convergence ICs are bad replace both of them also check the resistors that power the ICs as they may be open as well.
