Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

Here are some of the most common symptoms and example photos of a convergence problem

  • 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.

Here is a quick test....

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

Try to adjust the red and then the blue 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 commonshadowed colors inpicture - 2c07611.pngbr />

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

My 46F500 also had the same problem after 3-1/2 years. The convergence module was the culprit. The technician replaced the entire module at the cost of $550.00. If it happens again, I'll spring for a new tv. this is a common problem for projection tv's.

Shadow effect on picture. Picture is fine but there is a red shadow tint to everything (basically everything is written twice, but not in the same spot)

Color shadowing on screen


I had similar symptoms about a year ago. Also came on sudden. The red convergence chip had burned out (poor heat sinking on this model Hitachi). Replacing the color convergence chips fixed it. ($50 for parts.) First, however, have you tried the "magic focus" function? That's explained in the manual, which is available online IIRC, but I'd have to look for the link if you need it.
