Hello!you mean: colors out of convergence? nothing you can do about that, unless you replace 2 convergence amplifiers I.C. chips, plus all those burned 1 watt low ohms resistors with exact values, which only could be obtained via service manual or schematics. After resistor is burned, there is no way to read color code properly, due to partial evaporation of pigments. this is a "pro" job. If you try or tried, already to converge those "stubborn" crosses, there is more to do, even after you removed and replaced two 20 pin I.C. chips, soldered dead into sweep module, plus located and replaced resistors with precise values, you need to get your settings back to normal, by going into "factory service mode' or, at least into "convergence alignment" menu and fight with those crosses!Don't forget the white "****"! Otherwise, you will be re-servicing your set all over after 30 days of usage.good luck,Alex.

SOURCE: hitachi model 43fdx11b power light come on no


The set has failed in either the high voltage section or the deflection amplifiers. These are the most common because they draw the most power. Of course, it could be other failures as well it is indicative of overloaded power supply current and the protection circuit going into action to shut down the set. Also this has been an issue with the convergence IC's failing. But in both case you will need to have a technician replace those if needed or to diagnose it and find out the exact cause and do the repairs.

Please get back to us if you have further query else please accept the suggestion.

Thank you for contacting

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 common problem.

You need to replace the convergence chips and convergence resistors. Check the site 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.
