Problem for Hitachi 61SWX10B 61 in. Rear Projection Television
Hitachi television repair
The color convergence seems to be on the fritz. all of the images on the screen have red blue and green shadows around them. I have tried the magic focus system, but it shuts down quickly and the number 5 pops up on the lower right portion of the screen. Is there a cheap fix?
Same Problem
May 04, 2009
- I have a hitachi 53sdx89ba rear projection TV. I have convergence issues - primarily in red. After hours of on-line research, I have replaced both convergence IC's (110's upgraded to STK 394 160 E). I have carefully checked all resistors and replaced bad RK46 (1.5ohm, 1W). My operating manual and available service manuals (bought on-line) and instructions from TV Repair Kits.com do not seem to work for manual DCAM adjustment on this Hitachi TV. For example, if I press and hold Majic Focus I get two screens, first Center Mode then Static mode, but I can not move red cross or red line with any buttons on remote. These screens on not described in service manual, etc. I can not access the grid mode that is supposedly available. For example, the instructions from TV Repair Kits that begins:Press Magic Focus to begin magic focus
3) Press magic focus again during the magic focus process to get the "stop" screen
4) While stop screen is up, press STATUS or INFO on the remote control (R/C) to bring you to DCAM mode and
the service grid
... do not give access to service grid.
I have read countless blogs and boards and I can not determine if the hardware fix is bad (I find this hard to believe as I carefully soldered the two IC's in and checked and rechecked all the IC board resistors) or if I have a Software/Menu access issue. I have seen one poster say a fuse on the convergence board could be out, but I can not find the fuse.
Any suggestions appreciated. I have about 30 hours into this repair and am too stubborn to give up now.

- color is fuzzy and the lines on the tv is wavey--how do i fix the convergence or where do i go to get instructions on doing this on a hitachi model 50ux22ba- GuestMar 03, 2009
- I just have blue around the images. Although I have a 51 in.- GuestDec 14, 2008
- Our Hitachi also has the red blue and green lines toward the top left hand side of the screen as though the colors were not lined up properly anymore. We also tried the magic focus but it did not work at all.- Rubyshoes45Nov 13, 2008
- Was watching TV when it shut off. Power light blinked 5-10 times and turned back on. Now I have Blue shadows especially around the edges. - NighthawkJoeBest Solution

The convergence ic's need to be replaced. There may also be several resistors in the same area that are burned and need to be replaced.

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
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.
Solution #1
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.

Solution #2
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.

I had the same problem. I could not afford a new TV.
I called Hitachi for a local Hitachi repair center.
They replaced the convergence modules and cleaned the picture tubes.
They soldered some other items.
They explained that the convergence modules are the common repair for these TVs.
This repair is not for the non-professional.
The costs $512 with tax and one hour. I live in the New York Area.
The cost may be different in other areas.
$500 repair vs $1500 new TV?
Now my TV is like new.
I hope this helps.

I have the same problem - blue is ghosting - majic focus runs for a minute, then goes blank and shows a number 5
Comment by Guest, posted on Apr 01, 2008
Yes, i too have the same problem. I cannot converge the 3 colors using the interface, so I wonder if it may be a problem with the lamps. The green seems to be the most off.

I have ghosts when i first my tv on after 20 min i use majic focus and that clears the problem but if i turn the tv set off and back on the ghst are there
Comment by CTurp, posted on Feb 23, 2008
I'm having a similar problem. Mine is a green red ghosting. The red seems to be ghosting about 2 inches below the green across the top third of the screen. I opened up the TV and there is a distinct 1/4 grayish black line running just to the left of center on the red lens. Any relation to my problem? How can I fix this? Is it simply out of convergence? How could this just happen one day? Any help, suggestions or input is greatly appreciated.

hitachi model 51SWX20B purchased 3/6/03. Magic Focus gets 5 in lower left of screen. Tried manual focus, and green lines on left side of screen are wavy. Aligned red and blue, so picture is clear, but left side of screen is vertically wavy.

hitachi 53 projection tv with major convergence problem. red image is approximately 2" to the right of other images. tried the magic button to no avail. Wonder what next step is if any.
Comment by collier, posted on Dec 02, 2007
i have blue convergence problems is it true that if i change the convergence correction circuit 6 channels and output muting circuit this will fix my problem there should be two of these ic's ? and what circuit board are they located on ?

I have a Hitachi 61SWX10B, which was purchased in 2002, and my TV started having the color converse problem/3D type of issue a few days ago. I also stated having rpoblems with the sound where about a minute after I turn on this TV, either the sound disappear or it starts making some wiered noise.

my colors are not in sync anymore and my magic focus doesn't work after a few seconds on magic focus 5 just apears on the bottom of the scream.
Comment by Geo68, posted on Nov 03, 2007
Same issue but when using the magic focus it goes thru blue and green quickly and takes 20-30 seconds to get through the red. Magic focus does not fix. Alignment of colors in center appear closer to normal but red aligns higher toward bottom of screen and red aligns lower toward top of screen.
