I have got a Samsung SP43W6HL Projection tv

Hi guys,
The problem I have is with the convergence setting on my tv.
The picture is still giving green,blue and red ghost images at the edges of the screen, and giving me a factory data settings message....
How can I either manually focus the image or Reset these 'factory data' settings please?

Perfect Focus and the convergence screen are for convergence, not actual focus. Real focusing is done in a combination of two ways: electrostatic and optical. And to do it right you need a good test pattern, like the convergence pattern from the Digital Video Essentials DVD. At a bare minimum turn your contrast down to half (don't use "dynamic" mode, ever).

This is going to sound scary, cuz it terrified me at first but now I'm comfortable with it:

To focus electrostatically, the front panel under the speakers needs to come off. As in actually unscrewing some screws and opening up your tv. Do all of this without cats or toddlers in the room. There are three circuit boards on which the picture tubes are mounted, and each board has a focusing knob next to the words "red," "green," and "blue." Do not touch ANYTHING other than these knobs. Twist the focus back and forth until it is as focused as it will get. The lines on the convergence pattern will get fatter or skinnier. If they get fat in one direction and skinny in the other, find the best compromise. Do not focus the blue too perfectly, as perfectly focused blue lessens the amount of blue relative to the other colors, making whites look yellowish.

Next you really need to clean your lenses, they are filthy from dust and that's why the focusing is so bad. For this tv, you'll want all three panels on the front to come off. That's about twenty screws, both on the sides of the tv and the undersides of the panels. The middle panel that covers the speakers can rest on the floor by the front panel, but the screen panel needs a resting place. An ottoman, or a chair with a towel on it, makes a good place to rest the screen (parallel to the floor).

Each CRT has a set of focusing lenses, and these can be removed. Do one at a time. They come off from four screws each. FOUR SCREWS. Do NOT unscrew anything else, as just under the lenses is a cover for the CRT. Take this off and you risk coolant leak, leading to expensive electrical problems. Do not, repeat, NOT touch either the lenses or the mirror with your fingers. One scratch is bad. Scuff marks can destroy a picture. These lenses and mirror are easily damaged.

http://www.keohi.com/keohihdtv/learnabout/generaltips/screenoptics.html

There are some cleaning techniques there. I'd only bother cleaning the top and bottom of the lens assembly. Don't mess with the wingnut on the side, we'll handle that later.

Now, with your CRT lenses back on (wingnut facing towards the mirror), replace all of the panels and rescrew the screws. Next we do optical focusing. Again, this is where test patterns from a test pattern DVD come in handy. Regardless of what TV a person owns, a DVD like Digital Video Essentials is, well, essential.

This time we're taking a panel off the *back* of the TV. Scary, huh? Specifically, the bottom one (there are two big back panels). About fifteen screws, four of which are the same ones you do to get the front bottom panel off. Get all of the screws off, pull it back, and lift it out. Don't touch any of the electrical stuff. From here, if you are careful, you can reach up under the mirror and untighten the wingnuts on each CRT lens assembly. If you are using a test pattern, use a standard definition one here, makes the scanlines easier to see.

Here's what I do to focus each gun:
1) Put on a full screen of green, red, or blue, depending on which gun I'm focusing. DVE has just these patterns.
2) Untighten the wingnut, and start making minute adjustments.
3) What you want to see is *scanlines*, as clearly as possible. Make a tiny adjustment, get back around to the front of the tv, and see how well you can make out scanlines. An all-green screen should actually be a bunch of horizontal lines of green. If you can't make out these lines, you aren't focused.
4) If you don't seem to be making progress at all, switch to DVE's convergence pattern to make sure you haven't completely lost focus on that color. You want to start from good focus, and then fine tune very delicately.
5) You may find it hard to get blue-focus perfect. That's okay, really, as blue is a filler color. Green was very hard for me to see lines on, but it was a step up from not being able to see them at all.
6) You may find it necessary to go back and forth between electrostatic focusing and optical focusing adjustments to get them right. That's okay.
7) When it seems you've done the best you can, you're done. Put the back panel back on and rescrew all of the screws.

Now you need to adjust your convergence. You can use the user convergence menu, but it will only get you halfway there, because it only controls like nine or twelve points. What you want is to access the *service* convergence menu. With the tv on, press mute-1-8-3 on your remote (not pressing them all down, just in that sequence). You should switch to a secret built-in convergence screen.

I hate to tell you this, but the only way to save settings made in the service convergence screen that I know of is with a Samsung remote, not the Akai one. This tv is actually a Samsung after all, and the Akai remote is missing some buttons that the Samsung remote has. You can buy them off partstore.com, among other places. Here are what the buttons do:

7-allows you to control red convergence
8-allows you to control green convergence (what the screen defaults to)
9-allows you to control blue convergence
+100-turns red on or off
0-turns green on or off
pre-ch-turns blue on or off
circular direction buttons-moves the cursor to a new convergence point
channel up/down-moves the convergence up or down
volume up/down-moves the convergence left or right

ONLY ON THE SAMSUNG REMOTE:
add/erase-saves settings after blinking the screen and centering the cursor

If you can find a button on the Akai remote that does that, you won't need to buy a Samsung remote.

BTW, you'll want to do this service convergence on each scan rate. So one for 480p (from a progressive scan DVD player), once for 480i (s-video source or non-progressive DVD player), and once for HD (I use my HD DVD copy of DVE).

Well, you did the right first step. However, when the convergence outputs toast up they sometimes cause other problems. First would be the fuses that supply them voltage. These are pico fuses back in the power supply. Second would be open supply resistors that have opened up because of the excessive current draw caused by the whacked out convergence amps. When changing the outputs doesn't solve the problem it takes the repair out of the realm of the do-it-yourselfer. My recommendation is to let a professional take over.

hmm..not sure that is the proper solution...take a look at this 1st...

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 Sony2_bing.gif,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer2_bing.gif, 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

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

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.

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 from the link below.

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

93a1209.pngCONVERGENCE SOLUTION

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 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
