Convvergence problem w/ Toshiba 50H82

I am having a problem with the convergence in my Toshiba Rear Projection TV 50H82. It appears to be on the blue convergence. I can move and reset the red, but the blue won't reset. The picture has several "Ghosts" of blue to my right as I view the picture... I think I need a Convergence IC but I am unsure which I need to purchase. I noticed that someone else is having a similar problem from reading below, but as I read I was unsure which convergence IC I should purchase. Thanks for you help.

My Toshiba 50H82 television takes about 30 minutes to clear up and during that process, it shakes.It becomes clear but still has wavy lines at the top of the screen which is about 6 inches.


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

How do I know I need a new projection lamp? My tv


This set does not have a lamp. It has 3 crt tubes that converge to create a color picture. The convergance is off a little causeing this affect. Go into the menu and look for convergence or magic focus. You can download the owners manual from Toshiba website to do this. You will need the remote that came with the set.
