    The ICs arent really that hard to change. I would recomend doing the feed resistors if you change ICs. If youre not comfortable with soldering I would replace the whole circuit board, but they do cost right around 150.00 for a new board. But the boards easy to install takes about five minutes.

My rear projection tv used to have green lines , now the color seems off and now its blue lines... How do i fix it. Color going out??


If colors are skewed or looks 3d it is a convergence problem.

Some sets when the convergence grid is called up will have green lines--green is fixed and red/blue adjusted to it.

To tell you how to fix I need to know brand and model number.

These are typical convergence problems--no two sets will look exactly the same.

Blue will not focus causing "shadows". Magic focus will not solve the problem.


This tv have a problems call convergence,it dead.The tv convergence board the 2 STK convergence ICS and some or all it resistors are dead.These parts must be replaced to solved convergence problems.The shop will cost u $300-350 for parts and labors.

Red, Green convergence lines are wavy


Projection TV sets have two very common problems listed below.

Problem #1) Convergence


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. This is called convergence.

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,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Toshiba TP50G50 Theaterview picture is double with red color only


Your alignment is off. Go to the set up menu then convergence. hit right and you will be in the convergence menu. select the color that is not in alignment. The green line does not move. if blue and green are lined up the line will be cyan. if red and green are lined up the line will be yellow. when all three are lined up the color will be light. Best of luck!

My red convergence is out, and it will not change


when thes tvs get around 4 to 5 years old the convergence go's out on them there are 2 stb's or someting like that it may be stc's i can't remember what they call them it's been so long sence mine did 1 has probbly went bad i chould control the red but not the blue and sometimes when this happens it will also blow green fuses as well in my books they should put cooling fans in these tvs to help cool them there is to much heat inside the tv thats why they only last a few years before having that problem i have 3 of them and all three of them did the same thing you can check the remote eye on the front of your tv sometimes when there is a problem the green remote eye will flash acode but you will have to have the service manual to find out what what the code means

If you changed the ICs you need to adjust convergence, read carefully the instruction and alingn the lines using remote control commands. Is a long process. My tv loss convergence three times , i will never buy another samsung product. I told every body that i know that never buy another samsung product.
