Picture is wavy and double vision


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

Wavy green lines when picture is black


Check out this site. These TV's are known for the CRT's going bad. This site shows how to make adjustments that could help extend the life of your set. Take a look at the first picture, if the lines look like the ones in the picture this site "should" help. The picture shows a problem with the red but don't worry about the color, look at the lines. I hope this helps.

I am told my Hitachi 61SDX01B (UltraVision/Ultrascan) has "Green Geometry"


Sounds like a convergence promblem.

Here are some of the most common symptoms of a convergence problem.

Screen looks 3D
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed in or warped.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence or magic focus section.

Try to adjust the convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

Its a fairly easy fix on the Hitachi sets.

You can get a repair kit that includes all the parts from www.TvRepairKits.com. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself.

Hitachi 61SDX01B


The problem is called green geometry.There is nothing wrong w/the green pix tube.It is critical to get the green geometry

accurate because the red and blue convergence overlays on

the green.If you have more than an alignment issue,that will need

repair before adjustments are attempted.

57" Toshiba with wavy green/red lines "good overall picture"


Appears to be a convergence problem, the chips are located on large aluminum heat sinks. Check near the 2 or 3, STK IC's for + and - voltage usually 20 to 25vdc. If 1 or both are missing, check microfuses. They should both be close to equal in voltage reading, if not, turn set off after it has been on for 10 minutes, feel the heat sinks at each IC,if one is hotter than the other, replace both IC's or all 3 if it has them. Now check the small low ohmage resisters in and around the STK IC's and you will most likely find a few burnt or discolored and have changed in value, replace these or the new chips installed will self destruct.
