    Open up the back and you should see a large silver colored heat sink. The convergence ICs should be attached to that.

Magic focus runs half way & stops &showes a #4 ? one side of a face has a green outline the other side red


You may have a burned out convergence chip. But first, if you haven't already, you can try service mode to adjust convergence. Press the Magic Focusbutton, and then press it again to stop it, and then press the Statusbutton on your remote. Here's a link to the manual convergence procedure (scroll down). Warning-- When I did this the set got stuck in one of the adjustment screens. I had to remove the bottom front panel of the TV to reach the "little blue" reset button to get back a TV picture. But I think this is worth trying before replacing parts.

Hitachi 65SWX20B 65 in. Rear... Problem


Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip Failure ( common problem )

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 common problem.

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.


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.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.
