SOURCE: Blue and yellow shadows on my Hitachi rear projection TV

The color has gone crazy on you because your convergence IC's have gone bad.
These IC's operate at a very high temp, and usually only last 4-5 years. 
If you remove the back of the set, you will want to look for the BIGGEST heatsink in there, on that heatsink, you will see 2 lage IC's , probably STK392-110, or STK392-120's or something close...regardless - you can go on ebay to order the new ones, but MAKE SURE they are Genuine SANYO IC's and not counterfiet cheapies. the cheap ones may only last 2 months..
You will also need some "Heat transfer paste" - you can pick this up at radio shack.
Once you remove the old IC's, test all the large resistors near them.. pull one side of the resistor out of the board so you can check it out of circuit. they will usually have the value in Ohms, printed directly on the resistor, but you may have to use the resistor color code to find out what value they are....However, usually if there is any damage, the resistor will look like it has been HOT or fried. replace the IC's and any bad resistors, and you should be good to go.
If after replacing the IC's and any defective resistors, the convergence is still bad, make sure to use a multimeter to check ALL fuses on the boards, --- sometimes when the IC's go, they will take out a fuse to the convergence power supply. If you find any bad fuses, replace them accordingly!
Hope that helps!

SOURCE: Hitachi TV, has red ghost lines outlining image on screen! Help!

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.

Manual Convergence adjustment on Hitachi 43UWX10B


I would guess you missed a open resistor--there are only about 12 of them--how did you check them?

This set (43uwx10b) has a tiny blue micro switch on the front of the chassis---if you engage it from the front the set will go into the DECAM or convergence mode--let me know the CLU number on your original remote and I will scan and paste instructions---98% of the time if the set is wacked out and will not adjust one of the resistors is gone---ONE OF THE CHIPS GETS THEM.
