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).

SOURCE: Sony KP51WS500 Rear Projection TV,Convergence Problem

Your TV most likely has one of two possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem

  • 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.

f0900cb.jpg
Here is a quick test....

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

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

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

2c07611.pngSolution #1

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

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.

The chips are located on metal heat sinks with fins and are side by side. They are black(about 2 inches wide by 1 1/2 tall) and should have the STK-392-110 number printed on them in white.

Depending on your level of skill at this kind of work you may be able to do it yourself---if you need step by step instructions contact me---I have them in Microsoft word---start to finish repair including what you will need to do it.

If you are not able to do the repair yourself now is the slow time of year for TV repair shops----It should be fixable right in your home and the repair takes about an hour--I have done hundreds of these sets--some shops charge 300-400 but I do lots of them for 200-250 total cost. Make sure whoever you get changes BOTH of the chips!

Shop around and if they say "needs to go to shop" keep looking; any good tech can do this right in your home.

I do this here for free so if this helps you give me a vote here. If you need direct help contact me.

I have a Philips 51PW9303 Rear Projection TV that had blue shadows around the sides of the screen and now has a green and red bowed line at bottom. Does I need a convergence board to solve this?


If the following doesn't work the tubes could be at the end of life:
Adjusting convergence:
Note: For best results, the Projection TV needs to be turned on for 15 minutes or longer before adjusting the picture tubes (convergence).

To adjust the convergence of the picture tubes:
  1. Press the 'MENU/SELECT' button on the remote.
  2. Press CURSOR RIGHT to enter the PICTURE menu.
  3. Use CURSOR DOWN and RIGHT to select and enter MANUAL CONVERGE.
  4. Press CURSOR RIGHT to select CONVERGE RED or press CURSOR RIGHT and DOWN to select CONVERGE BLUE.
  5. A crosshair will be shown on the screen. If there is any red or blue fringe around the crosshair, use CURSOR RIGHT, LEFT, UP, DOWN to try and merge the fringe colors with the crosshair.
  6. Press the 'MENU/SELECT' button to return to MANUAL CONVERGE menu.
  7. Press the 'EXIT' button to exit the menu.
If you are satisfied with the convergence you may stop now. Otherwise, you can continue and adjust the convergence more using mult ipoint convergence.
To Adjust multipoint convergence:
  1. Press the 'MENU/SELECT' button on the remote.
  2. Use CURSOR RIGHT to enter the PICTURE menu.
  3. Use CURSOR DOWN and RIGHT on the cursor ring to select and enter MANUAL CONVERGE.
  4. Press CURSOR RIGHT and DOWN on the cursor ring to select MULTIPOINT RED or MULTIPOINT BLUE.
  5. A grid of crosshairs will appear on the screen. If there is any red or blue fringe around any of them, press CURSOR RIGHT to enter NAVIGATE mode.
  6. Use CURSOR RIGHT, LEFT, UP, and DOWN to move to a crosshair that has a color outline.
  7. Press the 'EXIT' button to enter ADJUST mode.
  8. Use CURSOR RIGHT, LEFT, UP, and DOWN to merge the color with the crosshair.
  9. Press the 'STATUS/EXIT' button to return to NAVIGATE mode. Repeat as necessary.
  10. Press the 'MENU' button to return to the MANUAL CONVERGE menu.
  11. Press CURSOR DOWN until SAVE MULTIPOINT is selected.
  12. Press CURSOR RIGHT to save the multipoint settings.
  13. Press the 'EXIT' button to exit the menu.

Pixeled picture, Red color, blurry and smeared images


Ghost image and snowy colorful pixelation with vertical black bars? You can try a hard reset by unplugging the unit completely for 4 hours. However you may have a prob with the YSUS and the YBU-L (YBuffer Upper-Lower.) Perhaps even the Logic Main may be defective. If you are still under warranty take it to a service center ASAP. If not Get out your Voltometer. You can email me for some help...

Blue Multipoint converge failure Philips 55PP9753


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

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,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with 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 - 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
