If the convergence will not adjust then 1 or more of the convergence amp ic's have failed. Most times just replacing the ic's will correct the problem, but sometimes when and ic fails there is other damage such as open or burned resistors or open cp (circuit protect fuse). If you want to reply with a make and model I can provide part #'s and locations.

Toshiba big screen Model TZ50V60 Convergence Issue-Chips Replaced


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. 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, Zenith, and others. You can get a convergenece repair kit wiith 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 - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

You can see some more examples and find a fix here

This is a convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$300

Cant get icns lined up can adjust side to side but


if this is a rear projection crt type set go into the customer menu and select CONVERGENCE--if either blue or red will not move up and down--you have a bad convergence IC---most sets use two of them.

Seeing doubles


there is an adjustment called convergence.the convergence setup generates a crosshatch.you need to adjust the red deflection.this is a common thing when the t.v gets moved.the crosshatch or convergence button is mostly on the front control panel.consult the manual for where it is.

My screen has a wave in it/red convergence won't adjust


You have convergence output failure. The output ICs will need to be replaced and possibly a small component like a resistor or two as well. Expect to pay a service company $350-$450 to resolve this.

Color adjust


Greetings!

Adjusting the picture tubes is a scary proposition, but since you have already done it...
The easiest way to balance the gray scale is to turn the color all the way down on the set. The next part is easier with two people if the screen controls are on the back of the set. This is the part you saw that has six small knobs on it. There are control for the focus of the red, gree and blue and for the screen level of the red, green and blue. You will want to adjust the screen controls in an effort to get the picture black and white (this is why you turn the color down), hence the term "gray scale". Just make slight adjustments, take your and be patient. It will take some time, but you will get your picture balanced back out in time.

Hope this helps!

Convergence issue


try fixing the convergence 2 after your've aligned the convergence 1 - the second (accessed via the set up control) let's you adjust on 9 different axis to align the red and blue tubes to the green. you select which + sign you want to adust by pressing the corresponding number for the + ie 1 for the top left, and 9 for the lower right corner.

good luck (note - you cant change the green only the red and blue, if the whole edge is a mess try moving the image (you need to be in zoom mode, and then access the position adjustment via the pitcure set up screen.
