    This is helpful - I'll take a picture for you.
    I sold the TV to my next door neighbor - it was working great - he moved it to his house and now exhibits this convergence problem. Thought maybe we just shook something loose.
    Thanks!

I have a toshiba tp50h50 rear projection tv and their is a blue shadow behind the words and makes the words a little blurry


Sounds like you need to do a color convergence. If you still have the owner's manual, it will give great detail on how to do this. The convergence menu is accessed from the video menu on the tv.
The tv has three color picture tubes, red, blue and green. The convergence alignment adjust each tube so that color from each tube overlaps each over to create a white image on the screen. Most tv's only allow you to adjust the blue and red colors.
Convergence should be performed each time the tv is moved and at least once annually.

At the bottom of the screen the words or picture is duplicated in blue in an arch pattern what is the problem


This is due to needing to adjust the convergence. Go to your menu using the remote. You may have to go into advanced to find the convergence option. This should allow you to merge the colors together on a grid. From time to time these projection TVs get this problem especially if they are bumped or moved. It's easy to fix. Make sure you sit of stand directly in from of the TV to move the color lines together.

Different ink settings banding


Try doing a printer head alignment, sounds like the printer heads are overlapping causing the banding.
Screen colors also never match perfectly to the print either, whist your monitor can produce millions of colors, the printer can only do some many.

Samsung HCN4727W Rear Projection TV, green screen, audio works


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,Akai2_bing.gif,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...

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

Printer prints words on top of each other


Check to make sure that there is nothing preventing the page from being pulled into the printer. Overlapping words is often caused by the paper feed not moving quickly enough, subsequently causing words to overlap and not span the entire page.
If that doesn't work, let me know and we'll troubleshoot further.

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


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 email and they will put one together for you. Their kits includes photo instruction guides, original Sanyo STK chips, convergence resistors, pico fuses, etc.

Colors overlap on left third of screen!


Yes it is convergence, but the first things to think about are. Did the set get bumped when you moved it? If so likely one of the guns is out of alignment physically due to jarring. However the other next best thing to look at, is if the set is near any type of magnetic object, mainly like a stereo speaker (larger ones) so if that is true, try moving it away slowly while the set is playing to see if it clears up. Lastly that the screnn itself is off or broken again a physical problem to resolve.
