Question about Samsung PCL541R 54" Rear Projection Television

2 Answers

Samsung pcl5414r 54 in rear projection. red all over screen

I have red wavy lines on the screen and everything on the screen has a red blur beside it. I could not get it to converge as the cross hairs were way off. I also have a electronics smell as if something is getting HOT. I removed the back and found that one of the IC's (STK392-040) was very hot. I replaced both IC's and still have the same problem. now I cannot begin to converge the red. it does not move. I replaced the IC's as i seen another problem similiar on the site and that was the solution. I am not sure where to go now. I do not know what is getting hot and making the smell. I would love to fix this t.v. it is only 6 yrs young and I have it recessed in a wall. the recess hole was made to fit the t.v.
thank you

Hi and welcome to FixYa,

Initially, were the power resistors on the same board as well as pico fuses checked/replaced? If not, the it is highly possible that the STKs were again damaged, would have to be replaced together with the said resistors and pico fuses.

Good luck and Thank you for using FixYa. Happy Holidays.

    Hi again and welcome back to FixYa,

    Appreciate the direct "Ask Me'.

    Based on your original post,
    only the STK ICs were replaced. Presumably 392-040, the surrounding
    resistors and pico fuses could very well have been affected as well.
    Depending on the board revision (pls confirm location numbering on the actual board), the resistors could be:
    RZ104 -RZ106 - 270 Ohm 1/2watt
    RZ133-RZ135 - 27K Ohm 1/16 watt
    RZ136 & RZ138 - 3.3K Ohm 1/8 watt
    RZ146 and RZ147 - 3.9 Ohm 2 watt
    RZ148 and RZ149 - 150 Ohm 2 watt
    while the pico fuses would look like the image below.

    Cheers.

The problem sounds like a burnt convergence IC (STK), have the ICs on convergence board teste and replaced.

    If you get wavy distorted lines, usually it is a convergence proplem. On the first case it was the convergence IC indeed, infact the problem was an STK392-040, that is a convergence IC.

    Replacing a convergence IC it is not a job for beginner, as you need to use thermal compound, and to do a precision soldering job inside the tv, after you test the pico fuses at the base of the IC to find out if the ICs had blown.

    An easier job is replacing the convergence board (always after testing the board, the problem may be elsewhere.
    Replacing the C board is easier than replacing the ICs, but more expensive, and must still be done by a technician.
    After replacing the faulty part , a convergence setup procedure must be done. You find the procedure on the service manual.

    You can call the phone number here to look for parts and service manual.

Picture show blurred and 3 lines across the screen color of red, blue and green


Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded over.

Red, Green convergence lines are wavy


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. 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

Red and green wavy lines


If the distortion that you see can be described as somewhat of a 3-D picture, the problem is teh convergence circuit and this can be fixed easily. Also, if you can solder, you can fix this yourself. If you wish to do this, please update this and I'll provide you with some instructions.
