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.

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.

I would like to know if the Hitachi 51UWX20B television can be connected to the internet.


Your Hitachi 51UWX20B is an HDTV-Ready TV. No Digital Tuner. HDTV-Ready means that your TV set is capable of displaying analog and high-definition digital pictures, but without a digital tuner, it cannot receive the digital signal. An HDTV-Ready requires an external high-definition TV receiver (digital tuner) in order to receive HDTV signals. These external receivers can be called an HDTV Tuner, set-top-box, decoder or DTV Converter Box . So you will be required to purchase a converter box to receive over the air programming from an external antenna.

Screen prob with Hitachi 51UWX20B red square


Maybe the best way to adjust the screen is with the manual magic focus..instead of letting the tv do the auto change it to manual and see if you can adjust the convergence yourself. I have this same model and once in the manual adjustment you want to make sure you see all white lines....if you seen any blue or red that is the color that needs to be moved towards the white line closest.

Once you think you have it lined up nicely hit "exit" on your remote and option 1....

Hope this helps you.

Double image/ out of focus with green and blue seperation


Your tv is crt-based and is out of convergence. In other words, the settings for keeping the Red, Green and Blue images aligned have drifted and must be reset. This is common with CRT projectors and CRT rear projection tvs.

Refer to your owners manual for instructions on re-aligning it.
