Your TV most likely has failure in the convergence circuits. ( 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.

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.

    Likely have bad convergence ics.

  • electroman May 01, 2009

    The parts are around $35.00 to $75.00 depending on were you get them. There are genarics STK395-110. Professional serv around $75.00 to $200.00 Plus a in home service charge. If you are looking for service if you say the convergence is ut and it won't adjust any tech that knows these type of sets will know what to do.Hitachi makes a kit that includes some resistors . I think their using STK395-150 in the kit. wattage upgrade.

My tv has begun showing a red shadow behind the pictures as well as letters, i have gone into the converge settings to resolve but cant figure it out


joeclaudiaag,

When the convergence will not adjust after you know you have set them correctly using your TV's convergence adjustment, your convergence board went bad. You can either repair it yourself with kits sold online (links below) but unless you know how to solder very well, opt for a repair guy. Your model will cost between $350 and $450 if you hire someone.

http://servicemanuals.vstore.ca/product_info.php/pName/hitachi-dp15-convergence-upgrade-kit/cName/convergence-repair-kits

If you like to tinker but not dwell into the soldering world, try finding the same model for free or dirt cheap on a web site like www.craigslist.org that still works but like where a kid jumped into the screen!, and swap out the board.

Good Luck! Please rate this answer if I was able to help.

My Hitachi cj 110 jig saw blade keep falling out I have tried different types of blade What?s the deal with that? I don?t know why someone would put a quick release holder on a blade shaft of a power tool...


WOW everyone really cant figure out the problem??? Take your jigsaw blade and hit it with some coarse sandpaper or a dremel and knock the finish off the edges and sides depending on maker and it willl work just fine. The blade companys put a super slick finish on the blades. not the saws fgault.

My hitachi tv's picture is distorted red and green like a 3-d pic


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony, Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit from the link below.

Common Symptoms include....
  • 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.
  • TV shuts off after powering on - TV may also make a chirping noise.

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution

Changed ic's need to reset picture every time i try keeps saing over load


If the convergence adjusts ok in the customer mode do not worry about the "overload" it only has to do with the Magic focus feature---

There is a way to overcome that but It is tricky and one wrong move and you have real problems--it involves DECAM--de-converging and clearing the set's memory of the convergence adjustments--It means the convergence has to be adjusted from scratch--I have seen this done by an expert and I have done it but no one not totally familiar with the process should attempt it.

You know there is a Tech Menu for fine adjustment of the convergence?

That is not hard to access but I have a Hitachi book that tells which buttons on the Hitachi remote do what in this mode---The remote will have on the face of it a CLU number--tells which remote it is.

If the convergence adjusts do not worry about the Magic focus--it only adjusts the convergence at about 16 places on the screen---in the Tech menu you adjust at over 60 places--much better way to go.

Get me the Clu number on your remote and I can scan the page from Hitachi---we will need to find a way for me to get it to you...............

I'm pretty sure the convergance chip is out. My problem is that I do not have the original remote. I have one made by Dynatron. I can't figure out which button is equilivant to Status, or ANT. Help please.


Almost any remote will work for this set if it is Hitachi--understand----if you have one of the two STK-392-120 CHIPS THAT THIS MODEL USES BAD--It will not adjust....

All of the Hitachi remotes will work but different ones use different buttons in the convergence mode--if the model is 43fwx20b it uses a Hitachi remote with the number CLU-4321UG... printed on the front of it.

If you get a different Hitachi remote let me know--I have a book from Hitachi that shows most of the remotes by number and photo and shows which buttons do what in convergence.

Let me know if you need to know how to replace the chips-----usually you can get a remote for this type of set pretty cheap on Ebay.....

I have 46ux13k hitachi tv and i need to know if there is atrick to adjusting the convergence.


Manual Convergence for the Hitachi. YOU WILL NEED ORIGINAL HITACHI REMOTE. NONE ELSE WILL DO
1. Receive an NTSC signal.
2. 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 (64 point grid).
5. When you first get in here? I believe red is the selected color by default (it is flashing).
6. To choose other colors to converge, use the following buttons on the R/C:
· “STATUS” - Green
· “0” - Red
· “ANT” – Blue

ONE COLOR WILL NOT MOVE. YOU WILL NEED TO MOVE OTHER COLORS TO ALIGN TO IT.
7. Start from the center of the screen and work your way out on one color at a time. I adjusted red across the whole screen to match green. Then I switched to blue, and adjusted that to green as well. After you adjust blue, you
may want to go back and adjust some red again? etc. until the convergence looks good.

· Use 4, 6, 2, and 5 on the R/C to move the cursor position (dotted lines).
· Use thumb stick to move the convergence point color.


Then going along the lines and adjusting, you may run into the problem of getting an ‘S’ curve on the line. You’ll know if you get there. Basically, no matter what you do to adjust the line to be converged, the middle of the line between the points will not straighten out (it bends between the points). To fix this, the manual recommends going to the (7x5) mode which gives you less points to adjust. I had this problem, and the solution worked. There is also another mode (3x3) which gives you even less points. Basically, if the set looks good, you only fine tune it in (13x9) mode (64 point). If you have serious problems, the grids work as:
3x3 – ‘coarse’
7x5 – ‘medium’
13x9 – ‘fine’
10) To get to each of these patterns use the following on the R/C: (only if you need to)
1. (3x3) Press “STATUS” 5 times (only works when DCU is in uncorrected state)
2. (7x5) Press “0” 5 times
3. (13x9) Press “ANT” 5 times
11) If you adjust the 3x3, then you should go to the 7x5, and then the 13x9. You get the point… depending on where you start, work your way up, and always finish on the 13x9
12) When finishing up the 13x9 mode, to get additional ‘grids’ on the edges of the screen, press the PIP CH button on the remote control while in the digital convergence adjustment mode (DCAM). Fine tune the edge convergence as necessary. To exit, press PIP CH again.
13) When convergence is acceptable, press PIP MODE to write data to ROM memory. ROM WRITE? is displayed to alarm system that ROM will be overwritten with new data. Press the PIP MODE button again to write displayed data to ROM.
14) DATA WRITE TO ROM will take approximately 4 seconds and no picture will be displayed.
15) Green dots will be displayed when operation is completed.
16) Press MUTE to return to convergence pattern, then confirm again convergence is acceptable.
17) Turn power OFF.
18) Wait a few seconds. Turn the TV on, and you should have your normal signal. Press Magic Focus button just to make sure the magic focus still works (and that you did the last few steps properly)

Hitachi rear projection


without knowing the model number, i can only give you some ideas on what to check.

If the tv was working fine, and started experiencing the problem after being moved, check your focus. you may or may not have an electronic focus pot on the rear of the tv, and you should have a manual focus located on the lens assembly, loosen the wingnut and rotate the lens to focus it.

also check the crt coolant level, if it has a bubble in it, it may be causing the red halo effect.

if the red is to the top or side of the characters and not completely surrounding them, it may be a convergence issue, check the manual for convergence procedures, if it does not have them, your best bet would be to take it to a service tech.
