Tv color has blue shadow

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

CONVERGENCE 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 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.

the tv had intermittant solder connections already but h\they appeared when the tv was moved to hook up the digi-box. The solution could be as simple as resoldering the power convergence amps.

Your TV most likely has a convergence failure. ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem

• 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.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

hi. this will be an easy fix for you if you are a good solder. you will need to replace the convergence chip that is located on the PC board(main). this chip is damaged and it has failed due to this damage that has occurred. click below for your new convergence chip(stk).

HELLO MY FRIEND. YOU PROBLEM IS THE CONVERGENCE STKS, WHEN THIS IC'S ARE BAD YOU HAVE NO CONTROL OF THE CONVERGENCE ADJUSTMENTS BY REMOTE CONTROL,IF YOU OPEN THE SET LOOK FOR TWO BLACK PARTS WITH SAME SHAPE AND NUMBER.YOU CAN BUY THIS PARTS ON LINE AND REPLACED THEM PRETTY EASY IF YOU HAVE REPAIR SKILLS AND ALWAYS REMEMBER TO UNPLUG THE SET BEFORE YOU DO ANYTHING.
YOU WILL NEED A SOLDERING IRON, A DESOLDERING TOOL AND SOME SOLDER, YOU CAN GET ALL OF THIS THINGS AT RADIO SHACK.IF NOT CALL THE REPAIRMAN HE SHOULD NOT CHARGE YOU MORE THAT $250.00 FOR THIS JOB WITH PARTS INCLUDED.
GOOD LUCK

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.

yes u need to go in to the menu where it says source and go to the convergence use the right arrow on your remote control it is a round ball u will come to a xross on the screen if the xross is nice and white in the center of the screen then u do nothing at that piont but if it is not hit your ratio button on the remote and your screen will change colors if it is green looking u can set the red lind if it is blue then u can set the blue line just read what it tells u on the screen to do.when u are done in the mode hit the round ball in the center and u can do all the x on the screen just find but please look at what it is telling u what to do on the screen i hope this will help it is very easy to set the convergance on the model set

Al, bring up your convergence grid (look in menu for it) and I think you`ll find that the set is out of convergence, if you can adjust the red up & down and the blue up & down your ok, if they won`t move in one or both directions the convergence IC`s will have to be changed out, hope this helps, BMW Rider

Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

Here are some of the most common symptoms and example photos of a convergence problem

• 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.

Solution #1

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.

Your best bet is to get a Zenith universal remote control.
