The most likely cause is shorted convergence chips and possibly a few pico fuses.
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 a convergenece repair kit with instructions from the links below.
Here are some of the most common problems with these sets...
Problem #1) Convergence
Yours may have one or more of the following symptoms...
*Screen Looks 3-D

SOURCE: my HD DLP Projection TV
Understand that I am not in the room with the TV. I can only give you information based on previous experience with this type of set.
I would diagnose this as a bad light engine. This is not a cheap part unfortunately (over $800) and a quick search of the web will turn up a lot of Toshiba DLP owners with the same problem. The light engine can be replaced by you if you are reasonably technically minded.
The only wise option would be to call Toshiba and feel them out. See if they will offer you any help. This model is a couple of years old so I doubt you have a warranty but they may be in a good mood and meet you half way with the repair costs - stranger things have happened to people who kick up enough of a stink.
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!

if a large rear projection set that just says HD, it likely is HD ready which means it needs a set top box connected to the Colorstream input marked 1080 on the rear of the set--It will only likely be 1080i and not p---owner manual would confirm this.
