Looks like it is out of convergence but the center
All projection TV sets have two very common problems. One is convergence ( 3D/Warped video or dead set) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.
Common Problem #1) Convergence has gone out
Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. In some cases the TV will also not show any video. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.
This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.
Common Symptoms include....
Here are some pics of convergence problems.
- Screen looks 3D
- Colors don't line up
- One or more colors can't be adjusted when using the convergence menu.
- Screen is bowed or warped.
- TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Common Problem #2) CRT Fluid is Cloudy
Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

I have a Toshiba 51h83.
this is normal with rear projection tv's its from long usage when the tv isnt always in full screen mode. you can sometimes fix this by replacing the bulb/ or the color board for the projector. also you can replace the screen as it seems like it may also be do to image burn in if it wasnt always in full screen mode. (did this for my uncles Mitsubishi projection tv)
let me know if that helps!

No video, sound only.
I am not familiar with your TV, but I might be able to help. Sounds like the lamp blew! These lamps only last about 4 to 5 thousand hours. There should be a lamp access on the back of your TV. unplug your TV and remove the lamp housing and inspect the bulb. Be sure not to touch the lens. If it is blown, replace with a new one!

Hello..Toshiba 51HC85, 2005 model. Turn on TV and
I've had the same problem for about the last 6 months. My workaround which was to leave the tv on 24 7 and just turn off the TWC service box. But now the symptoms are vertical dark lines going all the way across screen. My guess is that it will cost more to fix than worth it. I paid @$2000 for it new in 2004. Technology has gotten better so I may just go out and get a Samsumg for considerably less and be way better off. None of Toshiba's products had done well for me. 2 laptops, 3 tvs, etc. have taught me this.
