Curved screen and double letters

My tv has a curved screen and double picture. It had a convergence option and I have used it before and it seemed to do the trick. Now the auto-convergence option has disappeared, Am I missing something?

    OK. There are a few options for you. You ned to look at the model plate on the back of the set. There are variants of your model and the convergence boards are different. There may be a suffix after the model number that you posted. If not, then the convergence board is available for $9269 from tritronicsinc.com using part number 264103. If there is a suffix after the model number, please post that sufix and I'll update this with the correct part number and cost.

Picture seems sunk in and the color distorted with doubleing effe


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 projeciton 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

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 are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

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.

TV picture curves


This is a convergence problem and is usually either bad connections at the convergence ICs or defective ICs. If you can solder, you can fix this yourself. Locate the convergence ICs (large black Ics attached to a heat sink and marked STKxxx). Resolder the pins first. If that fails to resolve the problem replace the ICs.

Keep us posted.

Double print and curve screen


this is an indication of convergence problem. from your description the curved screen indicates complete loss of covergence. First question is in setup menu do you have the convergence option? if no then it will be the fl231 fuse problem. common to these set and if you can solder. its not a difficult repair. if you do have the option. then it can be any or all of three cuircit boards. let me know and i will do my best to see if i can help you fix it

Did you use the Automatica Convergence to try and straighten it out? If that does not help, you can manually adjust the convergence.
