Question about Hitachi 50UX57B 50" Rear Projection Television
Your TV most likely a convergence failure. ( common problem )
Here are some of the most common symptoms and example photos of a convergence problem
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 will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

If it is out of convergence, replace the concergence IC's. The are probly
STK392-110's, STK392-120's, or STK392-150's. Which ever they are, replace them both. Also look for burnt resisters near the heat sinks and Sub Yoke connectors.
Hope this helps,
