Convergence picture adjustment?

Recently I moved my Magnavox 51mp392h17 HD projection tv and now when I turn it on, the red and green colars are offset so for instance the screen shows channel 3. Its showing it twice one in green and one in red, one's slightly over labbing the other alittle higher. How can I adjust or fix that?

    I was able to adjust the multiport blue convergence, but the multiport red doesn't want to adjust properly.

    I have an rca tv that the colors will not converge together on and I was wondering how I go about finding the part?

  • Rayzor12 Nov 06, 2007

    I live in Machesney Park, IL. The multi point convergence blue worked, but the multipont red will not adjust, especially around the edges. I called around to try and find a tv repair shop to fix my tv with very limited sucess. The repair shop that Magnavox referred me to ( Schollmeyors) informed me that they have 3 other tvs in their shop with the same problem and that they currently don't know how to fix the problem.

    OK I have the sam eproblem. My tv worked fine last night and when my wife turned it on this morning the reds were way off. I tried the convergance and my red will move sideways but not up and down. Any help, if someone has a repair manual they can email me or any help would be appreciated. I've grown up working on radio and tv's in my fathers and uncles store but they are not around anymore. I know my way around a tv set but need the info on as what the problem may be and how to fix it. I see alot of other people are having the same problem so if someone could email me an answer or a repair manual, NOT a users manual, I have those. Thakns in advnace for any and all help forwarded to me.

    I am having the same problem with my Magnavox 51 inch projection tv. My problem with with the blue convergence. I cannot get the bottom left corner and the top right corner to align. I have placed the settings back to default factory settings and still nothing happens. When using manual convergence, the mis-aligned crosses will not move. Also, I am noticing that from day to day, the blue convergence has changed. I have to go back and redo it. Sometimes, I will turn the tv on and there is no problem, but after a little while, it goes back to being off again.

I had the same problem where all of a sudden it started bowing on top and bottom and the colors were bad. I read on here and other sites about the 2 convergance chips so I figured why not try as the tv was going to get thrown away because I could not find anyone that would touch it. Well I ordered 2 stk392-120's (I know others are saying use the 150's or 180's but I just wanted to put the same ones that were in there) I ordered them from electronix.com for 9.99 each plus 6.60 for shipping they took 3 days to get here and I installed them tonight and it worked great. The whole thing took only about 2 hours from start to finish. Here's a couple of tips....the chips are on the far left when looking at the tv from the back, make sure you mark with a marker where the wires go that you have to unplug as there are about 10 of them, each chip has 19 pins that you will have to soder make sure you have a soder ****** to get all the old soder up as you are heating them up, after you are done puting it back together leave the back cover off and turn it on, then go into your menu and go to pictureand go to manual converge and go to undo multpoint and restore factory as this will reset it all. Then if your color is still a little off as mine was there are 6 knobs in the back of the tv by the chips you were working on, find a channel with a lot of colors and try adjusting the top 3 a little at a time till you get the right color that you like. This should do it. It took 26 bucks and 2 hours for me to fix a tv I was ready to replace, thank god for the internet to be able to look stuff like this up. Good luck!

I just had the repair man out $400 he gave me the bad chips that are causing the problem and i looked up the part its only 7.99 it took him 1hr to do he also replaced some resistors but after googling the part number found some people giving out the resistors that need to be replaced. now i didnt see him replace so i dont know how hard it is to replace on your own but could be worth a shot had i known about the parts i needed i would have done it myself. Part No. STK392-150 He said STK392-180 would work too.

If the colors are only off by a little bit then you can go into the menu and navigate to the convergence page and realign the colors by following the instructions. Having the owner's manual is great for this. If the colors are suddenly way off, especially around the edges, then something has failed in the convergence circuits and should be repaired by an experienced tech. But from what you described, I believe a convergence touch-up is all you need.

You have a failure in the convergence circuits. I would seek a qualified technician
to do the work. One or both of the flat pack IC's Stk 392-*** are bad along with
some support components. If you are not careful You will ruin your tv trying to
fix it. Technicians are getting hard to find for a reason. Some of us are still
honest and need to earn a living. I just fixed one--Total bill $217. I don't know
anyone who can do the job in an hour. That was a trip and 3 hours working on
the set. Use this figure as a ballpark. Some set's can be bears to fix and may
run more.

My 52in hd tv wont show a picture and when you cut it on it just light up red but no picture and i cant get to adjust the convergence on the menu.


If the screen is a bright red its indicating an issue with the CRTs could be the red has shorted or the coolant in the blue and green is needing replacement which makes the red Dominate. Looking into the blue and green lenses will verify if its a coolant isssue or not. The convergence issue is most likley failed convergence ICs and the associated 6.8 ohm resistors need replacment.

Red and green are moving away from each other . projection tv not clear this way.


First you can try to adjust the convergence in the menu. You should be able to move the colors together to get a clearer picture. If that doesn't work, you most likely have a color driver issue and should contact a repair service.

Componants in back don't seem to work, HD cable,


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

The picture looks 3D


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 projection 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.

7859b01.jpg

e87380c.jpg
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

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.

Maganvox TV with red-shadow to picture


Hi Emily,

Your TV has bad convergence amplifiers. They are large integrated circuits that are mounted on large metal heat sinks. They have a part number on them, but might be covered up by a bracket. The part number should start with STK. They are replaced as pairs. You will have to find someone with the skills necessary to replace them.

Best Regards,
