Question about Televison & Video

1 Answer

Hello, I have a 50H82 toshiba rear projection tv and the red is out of alignment. I read your post and I tried doing the convergence option and i could align the red up to a certain point. The problem is that the red is more warped than anything. It's worst at the bottom left of the screen and gets back to normal towards the center so aligning it to the letters in the bottom left of the screen leaves it unaligned in the center (crosshair). I am still wondering if it is the Convergence chip or if it a bulb problem. thanks for your time.

The convergence chip is failing and is no longer capable of delivering the required current - you must replace it.

Shows a red scream


try the auto focus if shows error then try to do it manually in convergence and make sure you align all colors. If still doesn't work, then you will have to have the convergencs chips replaced.. Approximately $250 repair cost..

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
