Question about Samsung PCN5425R 54" Rear Projection Television

1 Answer

Convergence (red) is out of alignment

I have the same problem. I've used the controls to get it close, but not right yet. If I push perfect picture button it goes out of wack: I have to start all over again. Have you found a solution? Please share. It wants to adjust, just not enough (red) control.

    Where is the crt board?
    Where do I get freeze spray?
    Can I reset my remote to factory settings? Please advise

  • 1jvd Oct 07, 2007

    OK thanks for the info.above.
    The color seems ok, brightness is fine...Everything on the right side of the screen has a red shadow. Yesterday: first I got the center target right on. I spent a couple of hours moving the lower right target (left)closer and closer... Almost all the red shadow letters on screen were back where they belonged. At the very end I could not get them on perfectly. The left side of the screen looked a lot better, the right was still out. I hit the perfect focus button on the remote and lost it all. I do have the original remote. The remote made it worse. Can I simply reset the remote somehow? The set has received regular servicing under srvc.agree.(cared for). When I spray what do I look for? Please advise, and thanks for your help, I do appreciate it.

    Should I have the set turned on? While spraying?
    Nothing will explode?
    After spraying (red only) I will attempt to adjust with remote.
    Is the any way to lock the remote so that it brings it back into specs each time?
    I'm ready to give it a try!
    Waiting for your advise.

    What about the convergence service mode to do the alignments? Adjustable?

In your red convergence you have vertical and horizontal, pin, lines and etc. It sounds like you have a bad resistor in one of the areas. You would need to know which area to narrow down. Are you could look and see the problem, just look on crt board. I would take a can of Freeze and spray the board resistors until it changes then you could narrow down quicker.

    The CRT board is the board on the neck end of the tube, you have 3 for 3 tubes. The Green is always in the middle. You can get freeze spray from local Radio Shack or online at MCMelectonics, bluestar-online, tritronics, etc. Don't know why, but if batt. were out for atleast an hour it will probably reset to factory. If this is original remote.

    the remote is not your problem, either it works or not. There is no magic fix with it. Now the spray should either mess things up more or sometimes it will fix the things that are done by heat. It will cool it down and work like it should on those problems. I would only spray in the red area where you are having problems.

Convergence issue

try fixing the convergence 2 after your've aligned the convergence 1 - the second (accessed via the set up control) let's you adjust on 9 different axis to align the red and blue tubes to the green. you select which + sign you want to adust by pressing the corresponding number for the + ie 1 for the top left, and 9 for the lower right corner.

good luck (note - you cant change the green only the red and blue, if the whole edge is a mess try moving the image (you need to be in zoom mode, and then access the position adjustment via the pitcure set up screen.

Sounds like the digital convergence controls is possibly the item giving you the problem, if you have already changed the convergence board. You can get a used digital convergence board at the following link, just leave them a email and state your model number and what your needing.

Replaced Convergence Board picture still bowed

Today may be your lucky day. Approach this procedure with extreme caution and take your time. Sometimes when you replace that board you have to do a full digital convergence alignment. With tv off, push mute,1,8,3,power. Tv will come on in service mode. Certain buttons can now screw up the set in a major way, do not guess. press 7 to adj. red, 8 for green, or 9 for blue. Then look for the highlighted "x" intersection. Use directional buttons to adj. while careful to watch screen. Vol+ and - or ch+ and - make moves, mute moves cursor. If alignments move up, down, left, and right continue until all intersections are aligned. Turn power off to start over. When done press add/del on remote to save settings. That should fixya.
