Picture blurry The picture is blurry. I tried adjusting the five convergence points on this sets menu, but it still remains blurry. Does this require a tech to realign the TV? Can I do this or do I need a tech?

    It is a Mitsubishi VS-5047 projection tv. I tried setting the convergence on the main menu (which used a large plus on the middle of the screen), but that had a green shadow. I then tried the advanced (with the smaller 5 plus signs one in each corner). The screen is viewable, but still a bit blurry. Can I replace the convergence components myself? Where can I purchase them. not sure if it's work payin $250 (which is what I was quoted by my local shop) to fix it, or just put that towards a smaller (42") HD LCD.

    Most sets have an advanced menu also--if convergence will not adjust there--you have a convergence circuit problem--what is the brand and MODEL number of this TV?

The focus controls on this set are in the front behind the bezel. I'm not sure, but, I think on this age of Samsung, the screws to the front bezel are on the back side of the set. After removing the screws from the back, the front bezel snaps off and the door behind the bezel need to be removed. Watch the wires connected to the bezel, they need to be attached in order to turn on the set. The focus controls are on a black control block (there are three of them, one for each color). Adjust each color for sharpest picture. I use words on the screen for alignment. Each CRT board has a screen control (Adjust each slowly until retrace lines appear on the screen and then back off until they disappear). You may turn off the color and make sure that the picture is black and white. If it is not, then, which ever color is dominant, back it off a bit with that screen control. Facing the set, Red is left, Green is middle and Blue is on the right. Use only one hand inside an operating television. Do not touch the board, just the controls. This concludes television alignment 101. Any questions respond to this post and I'll reply.

You dont need codes for the service menu you need to repair the convergence circuit. If the lines wont line up in the customer menu they wont line up in the service menu either. Do you know how to solder? If so we can fix this yourself with a little instruction. Otherwise you will need to call a repairman. A good repairman will run you $300-$500 depending on your area. Let me know what you want to do.

SOURCE: Convergence Problem and Contrast Adjustment

Have you checked all of the resistors inthe convergence circuit as well? If not, check them for the correct impedance.. Remember, you have to pull one side of the resistor out of circuit to measure it correctly. 
If all of the resistors are good, then you have to do a coarse convergence adjustment on the set through the service menu.. if you need the service manual for the convergence directions, I have one uploaded in the technicians corner of techlore.com

Blurry picture


By focus is the set looking 3d etc--called a convergence issue---if so go into the menu with the Mitsubishi remote and see if it will adjust---if off and will not adjust in some area of the screen the set needs the convergence chips replaced.

If convergence is good and not the issue describe the problem a bit more----these sets have 3 picture tubes with lens---from rear of set (safest way) the lens can be cleaned with a lens cloth---dust on them will make the picture look darker and dull looking and usually is done one time a year--do not try to adjust anything until you try this first.

Mitsubishi ws-55515 intermitent blurry picture


A bad connection somewhere--when it happens if picture is 3d look in menu for convergence and call up the grid of lines--if they are not perfect you have convergence issue which usually requires parts to be replaced.

In this set sometimes the chips will become flaky and convergence will jump in and out.

Not a clear picture


CRT projection televisions need periodic maintenance to maintain a clear picture. Typically, to maintain a sharp picture, they require cleaning and alignment every two or three years. If the television is being used in an environment where there is cigarette smoke or other smoke sources, the optics inside the television can become dirty and cause the picture to blur. Additionally, CRT focus and alignment wander over time, or physical CRT alignment can be knocked out if the set is bumped or dropped. All RCA CRT projection televisions have an "alignment" or "convergence" adjustment in their adjustment menus, which are fairly simple to use. The convergence feature is usually accessible from the main menu of the television. Check your User's Manual for the procedure to touch-up the convergence adjustment and see if you are able to achieve a sharper picture. If the optics in your set have not been cleaned for several years, or if it is in a smoky environment, the picture will be blurry and usually a brownish color, In any case, since the set is several years old at this point, it's likely due for a cleaning. This is best done by a technician, and mostly involves physical cleaning of internal lenses, the refractor mirror on the back of the chassis, and the back of the opaque display screen. An adjustment of CRT bias controls and individual CRT focus adjustments will bring further improvement in the image sharpness and clarity.

Picture looks 3d and a little blurry


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

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

Mitsubishi WS-65611 Repair kit from TV-Repairkits.com no fix.....


I have a few ideas but they all will require some more information from you. I know these sets very well-if you fixed the convergence problem my hat is off to you--it can be a do it yourself job but not the most easy set to do it on.

Let me assume you adjusted the convergence in the customer mode--it does on any of the HD models have to be adjusted in the regular and then the HD modes.

The only other thing here that may be the problem is FOCUS. A simple way to determine this is to remove the back cover--turn the set on and call up the advanced convergence grid---then cover the lens for each tube one at a time--with red and blue lens covered are the lines in sharp focus or look blurry?

Repeat this with only red or blue not covered and see what you think--if one of the tubes is out of focus you will see it there--

There is also a TECH menu for adjusting the convergence-like the customer menu but it saves the adjustments into the set's memory--you will need to hit menu and a four digit code based on the actual model number of the set.

Check to see if focus is or is not your problem-easy to tell--green, red, blue lines will either be sharp or out of focus--if out ask and I will tell you the simple way to adjust that.

If this information has helped you rate this solution as I do this here for free.

you can try to clean the mirror and lenses. or try to adjust the focus for each CRT(picture tube). also could be a convergence alignment issue. check the main menu for convergence alignment feature.
