The screen is distorted ... double words and double picture


Hello,

It's a convergence issue. Go into the main TV menu under video settings and look for convergence. If it has an auto convergence select that and wait a minute the TV will adjust itself and give you a clear picture.
If the TV does not have an auto convergence and just regular convergence than select this. It will give you a grid pattern on your TV and you have to move the cursor (using TV remote) and adjust each "point" so that each line is perfectly white. If you notice red or blue anywhere on that "line" then you have to adjust using the up, down, left and right arrow keys to "line up the red and blue lines with the nearest white line. It takes time and patience to do, but when completed, all lines on the grid pattern should be pure white and you will have a great looking picture.
You have to do this will all TV inputs (Video1, Video2 and so on) the reason Zoom looks good, is because you never used that screen as much and so the lenses didn't have a chance to get out of synchronous.
RPTV's are made of the three lenses (red, Blue and Green) and as you watch TV, these lenses slowly get out of alignment. So you should do a convergence about twice a year to make sure nothing is out of whack.

Good luck in solving the problem....

You can pay somebody to do it, but may cost you like 100.00 or do it yourself, it is very easy just tedious and time consuming. If you have the auto convergence than your golden because this is the easiest way to "reset" the TV.

Since it is 4-5 years old it's a 50-50 chance that the TV has the auto feature. Good luck and if you still have the owners manual, I would read up on the convergence section in the manual.

Blue and red wavey lines and distorted picture


Projection TV2_bing.gif 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.

Convergence problems are very common on all Projection TV sets including Sony, Samsung2_bing.gif, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith2_bing.gif, and others. You can get a convergenece repair kit from the link below.

Common Symptoms include....
  • Screen looks 3D2_bing.gif
  • 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 - 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.

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 flash2_bing.gif 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 solution

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

Covergence out of alignment on 1/4 Vertical left side of screen


You need to manually adjust the alignment:
On remote, press Menu to get to the main menu
Then arrow down to "ADVANCED FEATURES"
Then press "enter"
Then Arrow down to "CONVERGENCE" and press "enter"
"Red Convergence" should be highlighted
Press "enter"
You now have Green, Red, and Blue overlapping crosses.
If Red is out of whack, use arrows to align
To toggle to blue (and back to red), press "VIDEO"
Then align blue cross
Once the crosses look aligned, and nice and white, press "AUDIO"
This will bring up the Advanced Convergence screen
This is a grid of the same overlapping colors
You have control over the Red and Blue
If Green is very out of whack, you'll need a repairman…
While the "target" is flashing, you can move it around the screen with the arrows
Place it over an intersection to adjust, then press "enter"
Now the "target" is steady (not flashing), and you can use the arrows move your color
When it's aligned, press "enter" again
Now "target is flashing, and you can go to the next square.
You cannot adjust every intersection.
Some areas need to be adjusted via the adjacent intersection
When you're happy with color you're working on,
Press "video" while target is flashing to change to the other color
Repeat the above (blue is much harder to see and adjust for me…)
When you're happy with the entire grid, start hitting "Menu"
Each press brings you back out one menu level, until you are out of them
Once you're used to the process, it should take no more than a minute or two.

Fine tuning grid on my Samsung HDTV with remote.(BP59-00048)


To adjust manual convergence on your projection TV, follow theses steps:
  1. Turn your TV on.
  2. Let it warm up for 30 minutes.
  3. Press the Menu button on your remote. The Main menu appears.
  4. Use your remote to select Function, and then press the joystick.
  5. Select Convergence, and then press the joystick. The Manual Convergence screen appears.
  6. Select Red, and then press the joystick. A series of crosshairs appears on the screen.
  7. Select one of the outside crosshairs by moving the joystick up/down/right/left or by pressing the 2 (up), 4 (left), 6 (right), or 8 (down) buttons on your remote. The method you use depends on the model of remote you have. Note: You must do the outside crosshairs first.
  1. In the crosshair you selected, if you can see a horizontal red line, use the CH up or CH down buttons to move the line so that it is superimposed on the horizontal center line of the crosshair. Note: Make the single horizontal line as white as possible.
  1. In the crosshair you selected, if you can see a vertical red line, use the Vol + or Vol - buttons to move the line so that it is superimposed on the vertical center line of the crosshair. Note: Make the single vertical line as white as possible.
  1. Repeat for all outside crosshairs, and then for the inside crosshair.
  2. Return to the Manual Convergence Screen, and select Blue, and then press the joystick.
  3. Repeat Steps 7 through 10 for Blue.
  4. Press the Menu button on your remote to exit.
Important: The directions above work for most Samsung Rear Projection TVs. Yours may be different. For exact directions to perform manual convergence, see your user's manual. If you don't have your user's manual on hand, click HERE to view your manual on line.
If you cannot get your Projection TV to converge, it may need to be serviced. To arrange a service appointment, call Samsung Customer Care at 1-800-Samsung (1-800-726-7864). Have your TV's model number and serial number on hand when you call.

Sounds like convergence issue--replace Stk IC's mounted
