Question about Mitsubishi WS-55819 55" Rear Projection Television

4 Answers

I believe that the convergence is going out, after a 2 minute warm period, the red jumps convergence and I can not manually adjust it back. If I shut the system down,after acouple minutes I can restart, but the heating cycle is shorter, and the red moving out of convergence is even sooner. Is there a componet that controls this that I can replace?

    You need to replace the two STK-392-570 convergence chips this set uses
    along with any of the 3.9 ohm protect resistors in front of them that
    are bad. The best way to do this is to get the middle board with the chips out of the set--- I
    have START TO FINISH, STEP BY STEP INSTRUCTIONS FOR THIS REPAIR ON THIS
    MODEL--they tell you everything you will need and how to do it yourself. You
    can buy a pair of the Chips on Ebay for about 12 dollars plus shipping
    (I can tell you the seller there to look for--I buy the chips I use
    there). If you have the original remote after you replace the chips etc--you adjust the convergence with it. These are very good sets and were not cheap when new. If you want the instructions let me know--I cannot post My email here, but you.......... If this information helped you, rate this solution as I do this here for FREE. SD TECH

Tv out of foucs


These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

Double and curved image on blue warm-up screen


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

There are manual settings on most projection tv's to adjust the size and to bring the picture down so it is centered on the screen better. Try adjusting the three colors mentioned below first. All projection tv's are pretty similar. If you need to adjust the picture manually, which you should not have to, there are manual knobs behind the front of the tv or at the rear. They should be marked for thier function.

Here is how to adjust the convergence one color at a time.You should be able to get to the convergence screen with your remote. You need to go into the setup screen and read what is on the menu there. It should say how to adjust when you get there.

Convergence- The Auto convergence feature automatically adjusts the TV’s tubes
(this may take several minutes, after which you can make fine adjustments to the
convergence settings); Red convergence displays the Red convergence screen,
allowing you to use the arrow buttons to align the red and green images; Blue
convergence displays the Blue convergence screen, allowing you to use the arrow
buttons to align the blue and green images.

Also this is in the manual for a generic projection tv.

Call 1-877-RCA-HDTV and have your unit’s date of purchase and model/serial number ready.
• A representative will troubleshoot your problem over the phone.
• If the representative determines that you should receive service, they will provide you with the name(s) of the
Authorized Service Center in your area.
• Contact the Service Center and arrange for home or pick up, repair, and return service, provided that your unit is
located within the geographic territory covered by an Authorized Service Center. If not, you must take your unit to the
Service Center location at your own expense, or pay for the cost the Service Center may charge to transport your unit to
and from your home.
• Proof of purchase in the form of a bill of sale or receipted invoice which is evidence that the product is within the
warranty period must be presented to obtain warranty service. For rental fi rms, proof of fi rst rental is also required

Here is a link to rca tv manuals if you don't have one.
You can download them in pdf.

If this is not a help, please give the specific model number.

Hitachi 43FDXO1B Convergence?


Manual Convergence for the Hitachi. YOU WILL NEED ORIGINAL HITACH REMOTE CONTROL. NONE ELSE WILL DO.
1. Receive an NTSC signal.
2. Press Magic Focus to begin magic focus
3. Press magic focus again during the magic focus process to get the “stop” screen.
4. While stop screen is up, press STATUS or INFO on the remote control (R/C) to bring you to DCAM mode and the service grid (64 point grid).
5. When you first get in here? I believe red is the selected color by default (it is flashing).
6. To choose other colors to converge, use the following buttons on the R/C:
· “STATUS” - Green
· “0” - Red
· “ANT” – Blue

7. Start from the center of the screen and work your way out on one color at a time. I adjusted red across the whole screen to match green. Then I switched to blue, and adjusted that to green as well. After you adjust blue, you
may want to go back and adjust some red again? etc. until the convergence looks good.

· Use 4, 6, 2, and 5 on the R/C to move the cursor position (dotted lines).
· Use thumb stick to move the convergence point color.


Then going along the lines and adjusting, you may run into the problem of getting an ‘S’ curve on the line. You’ll know if you get there. Basically, no matter what you do to adjust the line to be converged, the middle of the line between the points will not straighten out (it bends between the points). To fix this, the manual recommends going to the (7x5) mode which gives you less points to adjust. I had this problem, and the solution worked. There is also another mode (3x3) which gives you even less points. Basically, if the set looks good, you only fine tune it in (13x9) mode (64 point). If you have serious problems, the grids work as:
3x3 – ‘coarse’
7x5 – ‘medium’
13x9 – ‘fine’
10) To get to each of these patterns use the following on the R/C: (only if you need to)
1. (3x3) Press “STATUS” 5 times (only works when DCU is in uncorrected state)
2. (7x5) Press “0” 5 times
3. (13x9) Press “ANT” 5 times
11) If you adjust the 3x3, then you should go to the 7x5, and then the 13x9. You get the point… depending on where you start, work your way up, and always finish on the 13x9
12) When finishing up the 13x9 mode, to get additional ‘grids’ on the edges of the screen, press the PIP CH button on the remote control while in the digital convergence adjustment mode (DCAM). Fine tune the edge convergence as necessary. To exit, press PIP CH again.
13) When convergence is acceptable, press PIP MODE to write data to ROM memory. ROM WRITE? is displayed to alarm system that ROM will be overwritten with new data. Press the PIP MODE button again to write displayed data to ROM.
14) DATA WRITE TO ROM will take approximately 4 seconds and no picture will be displayed.
15) Green dots will be displayed when operation is completed.
16) Press MUTE to return to convergence pattern, then confirm again convergence is acceptable.
17) Turn power OFF.
18) Wait a few seconds. Turn the TV on, and you should have your normal signal. Press Magic Focus button just to make sure the magic focus still works (and that you did the last few steps properly)

Sounds like bad solder connections on the convergence circuit board. Better get it looked at before the damage becomes permanent.

Double lines


There is a manual convergence setting. Press Menu until you see the option of convergence. Save settings by pressing Power until you see Save Ok. You can exit the convergence screen by pressing the PIP button. 0 reloads the convergence. It will periodically go out of wack again.
