Hello,

I posted this recently, but it applies here also:
This sounds like a convergence problem which means that yourconvergence amps have malfunctioned. You can change these out yourself,however you will also have to change out all of the biasing resistorsconnected to the amplifiers. To do this:

1) Unplug the TV and then get a schematic of the TV I use http://www.servicemanuals.net or http://www.manualsparadise.com
2) On the schematic locate the STK329-xxx series IC packs (usually attached to a large heat sink)
3) determine if the STK329s are 110, 120 or 150.
4)if the STK329-xxx's are 110s replace with 110s (forget that upgradestuff it is a hit or miss game that I don't believe you want to getinto), if they are 120s replace with 120s and so on.
5) Now toreplace the STKs: remove the module from the TV and unsolder the oldSTKs along with the bias resistors, and replace them with the new ones(be sure to apply heat sink paste to the STKs when attaching them tothe heatsink)
6) make sure there are no short circuits form your soldering job.
7) Reinstall the module and then turn on the TV.
8) do an auto-convergence test and then things should be back to normal.

Now if you think you can do this have at it, if not I would suggest that you have it done by a qualified TV technician.

Thank you,

I hope this helps,

R56w36 convergence problem. color misaligned. Ghosts.


Dear Sir:

Thank you for contacting fixya.

Please follow the steps below.


green is fixed so you have to move red and blue to green.
by using the remote you may find a simple converge function and open this and using arrow keys move the blue or red first to center of screen, repeat for other color you should see the lines moving toward a a white center point.

if the lines do not move with remote try manual ...menu on the set. if still no movement you have a problem on the convergence board and need a tech to fix.

A service manual will explain complex convergence to the detail .
but this might take hours to get it right.

Please feel free to get back to me If you need any further assistance.
Regards,
Mohammed.

I would go out and get a replacement Universal remote with menu keys. Set the code for your TV and try that. You may need to activate the menu with the old remote and then do the adjustments with the Universal remote. Older sets work with most Universal remotes real well. make sure you get a remote that supports MENU functions.

My tv went multi colored take it as it looks like a 3d television


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 projection 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

The red bar is falling from th etopof the screen


Below are two of the most common problems encountered with projection TV sets.

Problem #1 - CONVERGENCE PROBLEM

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 Sony 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.

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 TvRepairKits.com

Their kits include a step by step instruction guide, original OEM Sanyo2_bing.gif STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Problem #2 CRT Fluid is Cloudy

Projection 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 video.

Pic of a set that needs the fluid changed. Notice how dull the colors are and how white the screen looks. The screen may also look red, orange, dull, etc.

BEFORE

Set after fluid change. Notice how bright the colors are now. Everthing looks crisp and sharp again.

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

My colors all of a sudden went out of wack


Is there an advanced convergence setup anywhere in the menu where the screen displays a grid? If so, you might want to get into that and move along the grid to each section that looks off. Adjust until the color falls behind the gridline, and move on to the next. It can be a time-consuming process, but should take care of your convergence issues.
