The reason you can not adjust it is because there is hardware failure in the convergence board.
Visit this website and ask them for a convergence assembly for your TV. Once you replace that assembly, the convergence might still need to be adjusted manually.
Good Luck.

Projection TV no picture flashing horiz arcs across top of screen sound okay


You will need convergence work to this unit. Not cheap.(Not recommended for DIY unless already experienced in this type work). Might contact a local servicer experienced with Toshiba & see if they can give you a quote over the phone. Be sure you are sitting.
This is probably a good time to consider entering the 21st century & look at LCD or LED flat screens.

I have some distored blue color across the screen


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. 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.

Convergence problems are very common on all Projection TV sets including Sony, Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit from the link below.

Common Symptoms include....
  • 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 - TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

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

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

Blue Ghost from Defective Blue


this is the convergence IC's that are causing this and if you can replace them( unsoldering and soldering them ) then going to an electronic parts store to get your IC's for your set is what you will need to do , here is an example of the convergence IC's http://www.nteinc.com/specs/7100to7199/pdf/nte7178_81.pdf
if you need further assistance then just let me know and i will help
otherwise hope this info is at least worth a fixya

Usually this means convergence ic's have to be replaced and possibly a few resistors on small convergence board. Sometimes it requires digital alignment after new parts are soldered in. This repair can cost 175.00-375.00.

Blue Halo Across screen


Hello Damianian, I too have this hdtv and had problems with the convergance and self-focus within the first year of ownership. I called Samsung within the waranty period and they sent out a tech who replaced the convergance board for free and did the manual convergance in my home. After this, with the new upgraded convergance board installed, the self-focus was not necessary anymore so I turned it off. Some time later the convergance needed done again so I called to get a price on them coming out again to do it. I didn't like the quote they gave me over the phone (around $200.00usd) so I looked for a Service Manual online and found one on an Ebay store for a total of $13.00usd including shipping. I now perform the manual convergence on this set myself and it's easy to do.
Anyone wanting to get a Service Manual for their hdtv or other technical device should check these guy's out. They now have their own website. http://www.thecdguyz.com/
I hope this helps, good luck!
