Question about Hitachi 60UX58B 60" Rear Projection Television

Blue tube not aligning

I was recently given a 10 year old Hitachi 60ux58b TV. I was told that it had a problem with the blue projection and if I could fix it, I could have it. So... here I am. I'll try and describe. Basically, I moved the TV in, ran Magic Focus, and it worked fine. A day later, the blue tube seemed out of alignment... it causes somewhat of a blue shadow to everything. Especially noticeable on words. I got the TV into manual adjustment modes, but I can't get the blue line to move. The red will adjust with no problem. So I've obviously got an issue in the convergence area somewhere. Can anyone shed some light on where to look? I'm looking for the service manual and schematics for this unit, unsuccessfully so far. I guess I would rather try replacing circuits/chips/etc myself, rather than spending $500 for the local repair shop. It's good learning for me, and if I do break it, I'm only out the cost of parts. If anyone can recommend a solution or where to look for the manual, I'd appreciate the help.

Re: Blue tube not aligning

I realize that you posted this almost two years ago but I was wondering if you were able to get it fixed. I have the same tv that has the exact same problem from the looks of your picture. Let me know how it worked out for you. Thanks

Re: Blue tube not aligning

The IC's are IK04 and IK05 on Hitachi TV's. They should be STK392-110's you will need to replace the one that controls the blue. On most Hitachis just resoldering the IC's will fix the problem but, if not I would replace both if you do anything.

Re: Blue tube not aligning

You are right about the convergence. You need to replace the part which controls the blue alignemnt or open the case and see if the wire is shorted. The could be why it moved a little one day and then got nothing. If you can't replace just he blue convergence/alignemnt component you will have to replace the entire alignment fixture. I would ask a tv repair shop in a big city or call the company's own repair holine and see if they can suggest the fix or get you the part at least.

50" hitachi 10 years old has blue and green colors

Your TV most likely has one of two 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 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 that includes replacement coolant, photos. instructions, etc

How do I aling colors: the red and blue colors are not align making the tv look distorted.

On my Hitachi there's a convergence button on the front panel. Press that button which will give you red & blue lines. You have to use your remote to converge (align) those lines to correct the picture. If the lines won't converge I've been told it could be a bad convergence IC & tech is needed to fix...could be approx $300 to fix.

All color guns out of alignment

Needs convergence amps replaced. Sometimes resistors burn and need to be replaced. This repair requires soldering/desoldering equip. and a trained eye, but usually can be done for 175.00-325.00 at a reputable service center. Good luck, Russmann.

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.
