Samsung HCL 552w convergence problem

I have a samsung HCL552w tv that has had a "ghosting"picture problem in the past, i had an extended warrenty through sound track and when this problem happened, they said it was a convergence ic amp circut board problem and they replaced it and said that that should have never happened and with the replacement board, it should never happen again. well, guess what, now the warranty is up, and the same problem has happened again. i have been reserching this on the web and found out that this a nation wide problem, is there any way that samsung can be made responsible for this faulty circute board so i dont have to keep paying for somthing that is not my fault but the fault of an faulty ic amp board? thans

Its the ICs that keep burning out. If you would like I can post a link where you can get the new ICs along with the step by step instructions on how to do the repair yourself. This is a common problem for all projection TVs. It is a very easy and inexpensive repair, most shops try to sell the entire board.

Bottom of the tv is warped lines


See attached photos and if set looks anything like this you have a convergence problem---set in customer menu has a way with the remote to attempt to adjust this--if will not adjust in some area of the screen parts in the convergence circuit need to be replaced--let me know what you find and I would be happy to give you advice.

No two sets with this problem look exactly the same but these pictures should tell you if you have this problem or not.

Our tv just started having a fuzzy image and the auto focus function aborts during the red color alignment. is there a manual alignment I can do to fix it.


What does this fuzzy image look like? Does it have ghosting shadows. Of course it is possible to align red manually from the convergence menu. But first lets confirm that it is indeed a convergence related problem.

Samsung tv model # HCP4363WX Ghosting


The convergence board that you replaced will not correct the issue that your describing as your model has the convergence amp circuits located on the Deflection board. You would need the deflection board which is available at the following link. It also has a picture of the board which is in your model its the large board on the right with the Flyback and both Convergence ICs on it.

Words and picture are doubled in red and green as though the lenses are not lined up hcl552w


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

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. Power light will blink. 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. And you should be able to get the grid straight.

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 fix

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.
