There are two or three convergence modules in the TV that have to be replaced. They solder to the circuit board. You can get these parts at shopjimmy's web site if you feel you can fix it yourself. Otherwise prepare to spend $400 plus parts to have a shop do it.

I have a Toshiba CT-90121 and my convergence is off. I can adjust the blue and red in the menu but cannot aline them with the green crosshairs. Do I need a new green projector or something else?


You need to remove the convergence Board and repalace the convergence IC's and and replace electrolytic caps and check for resistors that have changed in value. You can getb the parts at www.mcmelectronics.com com or just purchase a new board at www.partstore.com .

Rca big screen 5-8 years old, power shut off this morning while watching then when I powered it back up now blurry and has a red and green outline around everything onscreen


If you have the original remote to that tv, click on menu, then select set up from the on screen menu, then select convergence. you might see auto convergence as well as manual for blue and red convergence.

If you see Auto, select it, this will line up your tubes.

If no auto convergence, you will have to select each one, and follow the instructions to aline your tubes.

Picture is distorted w/ aline on top and bottom


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.

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

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 - 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 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 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

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Samsung 42" projection green and only green out of focus? Bulb? Tube? IC?


Just had new Ic?? Meaning single?? The symptoms you're describing are a convergence failure. That unit takes Stk392-040 Sanyo Ics and be aware there are a ton of Chineese knock-offs out there that can cause you real trouble, so purchase them from only a reputable part distributor... You need to change both amps, test all 3.9 ohm-2w resistors in that circuit, like Rz123 and Rz124 and check Fd102 3.5a pico fuse for open. That's actually a really easy set to work on for convergence problems because the entire convergence amp board is easily removed.
Good luck!

Convergence


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.
