Convergence I was messing around with the convergence box, however it seems to be locked and I can no longer get back into the convergence box. Everything is in 3D now and I can't get back in there to try to fix it! Do I need a password or something to get back into the box? do if fix what i broke. Or do I have to call a repair man?

You probably need to get a Sony TV Convergence Kit. More information can be found using the link below.

Convergence Symptoms:
  • Screen Looks Distorted/3D
  • Colors wont align
  • Screen may look distorted
  • No Audio/Video - makes a chirping sound.

The convergence box keeps going out.

this 3d effect is due to what is known as convergence.i work daily on these set in the shop. (thats a good testomony for these LOL) but the first question i ask is 1 in the customer setup do you have convergence option.. Next question is the picture bow tie looking and 3d. if you are missing the convergence option chances are it is the fl231 fuse. then you need to read the fl231 fuse under tips and tricks section of this website. Convegence is controled by three cuicit boards. if any of these need to be replace a technician may need to set or adjust the convergence back to faactory specs

Convergence is all messed up

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs.

You have a convergence problem.  Here are some of the most common symptoms. 
Screen looks 3D
One or more colors can't be adjusted when when using the convergence menu. 
Screen is bowed in but stationary.
You need to replace the convergence chips and convergence resistors.  Check the site They have put together a kit for your exact model. The kit inlcludes a photo instruction guide, original Sanyo STK chips, convergence resistors,  etc. Everything you need to fix it yourself.

Philips 60 rear projection hdtv looks 3D

If your red convergence controls will not remove the red in all four directions, you have a faulty convergence IC. You will need to replace both. They cost around ten dollars each. Let me know if you need anything further.

Blue out of whack around sides

I have the convergence problem with the red. After reading your site I replaced the 2 ICs and the problem is worse. Before the only problem was I could not adjust the red horizontal. Now I have no control over the vertical or horizontal and the overall picture is very red and it bows at the top and bottom very bad. A friend said I might have the ribbon connector in wrong or the convergence (silver box?) box maybe bad. Any ideas? Thanks,Dave.
