Re: Cannot align/converge using on-screen menus

This problem requires you to access your advanced convergence menu. It is too complex to explain here, and you can really mess up your TV if you are not careful, so make sure you read all instructions and record ALL settings of your television before trying this. It is really not too difficult to make simple convergence adjustments, but you DO want to read the instructions on the site I'm about to recommend, before pursuing this. You can access the service menu by pressing MENU, then 0159. Before trying this, visit the link below, where you can find complete instructions, under the Mitsubishi Tweeks forum: There is a $25.00 membership required to make full use of the site, but it is well worth it. I, also, have a WT-46809 and discovered this website two years ago, when I signed up for HD television with Comcast. The time and money spent has been well worth it. It was like a whole new TV when I was done.

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.

Convergence Quit

Projection sets have two very common problems.

The first common problem is 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 televion has started showing a blue and yellow douwble vision on the bottom of the screen?

Have you tried going to the service menu?
Do this by holding "MENU" on the TV set while it is on, then pressing "Menu" on the remote. You may have to do this a couple times for the menu to appear.

There should be a option on the appearing screen for Convergence, which has more options the the standard menu. To work this under the "9" setting for convergence, each of the + on the screen is the corresponding button the the TV remote (3 if top right, 5 is center). Use your volume or arrow keys then to move the selected + in the desired direction.

Use the [TV/Video] button to switch which color you are aligning, trying to align Red Green and Blue so they overlap, making white.

Good luck!

Convergence problem

You can download the manual here. Insrtuctions for auomatic convergence are described. I copied the instructions below.

Automatic Convergence
Your HD Monitor’s picture tubes might have been disturbed during delivery or
after you moved the HD Monitor, causing the color in your HD Monitor to be
out of alignment. The colors adjust by starting auto convergence.
IMPORTANT: Auto convergence works best once the HD Monitor has
warmed up for at least an hour. If you've just unpacked your HD Monitor,
it's a good idea to repeat the Auto convergence function when the
HD Monitor's been running for at least an hour. See page 38 for more
information about Auto convergence.
1. Press OK to begin auto convergence.
2. When the auto convergence is complete, the Red center convergence menu
appears. The cross in the middle of the screen should be yellow. If it is not,
use the arrow buttons to move the red cross to overlap the green cross.
Press OK when adjustments are complete.
3. The Blue center convergence menu appears with a cyan cross in the middle
of the screen. If it is not, use the arrow

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from and do the repair yourself. Its a fairly easy DIY fix.

Touch-up Convergence adjustments Enter the Digital Convergence Mode (DCM) by entering 0-6-2-5-9-7-(Status or Index) on the Remote control. The following menu will appear: Select an active channel or Aux Input. A signal must be applied to the set when performing convergence. If any Customer Adjustments need to be made, the Menu button can be used to toggle between the Customer Menu and DCM. The MPOSD ADJUST is used to center the Customer Convergence grid. A highlighted cross will appear along with the Convergence alignment grid. The highlighted cross should be centered onto the center of the Convergence grid. To perform a Touch Up Convergence, highlight SELECTION and press the right cursor button on the remote. The following menu will appear: Selections STORE, RESTORE FACTORY, and RESTORE DEFAULT are not shown after selecting SELECTION. Press the cursor down button on the Remote for these selections to appear. RESTORE FACTORY loads Convergence defaults from the Factory Loaded section of the Convergence Memory IC. RESTORE DEFAULT loads Convergence defaults from the sets software. To perform a Touch-up Convergence: 1. Enter the Convergence Mode and select RED TO GREEN or BLUE TO GREEN. Do not select GREEN (Green Geometry) without placing a Template over the screen. To perform Green Geometry, refer to the Complete in-depth Convergence. 2. Use the Cursor buttons on the Remote to Navigate from one adjustment point to another. Press the Status or Index button on the Remote to select ADJUST. Use the cursor buttons on the Remote to adjust the Red to Green or Blue to Green. Press the Status or Index button again to navigate to the next adjustment location. 3. After Convergence alignments are complete, press the Menu button on the Remote to return to the SELECTION menu. 4. Highlight the STORE selection and press the right cursor key on the Remote to save changes. 5. Use the GREEN TO RED or GREEN TO BLUE selections to perform convergence when the Green CRT has been replaced.
