Is there a way to manually adjust the convergence on a Hitachi HDTV modol #43FDX15B?


Hi James,

If Auto Focus (Auto Convergence) won't complete the set-up stop trying to adjust it. There is a fault in the convergence circuit!! ICs have to be replaced and maybe some burnt resistors.

If you access the service set-up menu and try to adjust the "defective" circuit the Auto-focus may not work correctly after the IC's, etc are replaced. Experienced technicians know that the service menu allow easy resetting to correct the misalignment, etc. "First Time" technician can be easily misled, waste a lot of effort and never get a correct picture.

If you want to attempt the repair, buy the correct parts from a service guy that does this type of work. I suggest having the repair done by a local competent technician that is experienced with Hitachi Convergence Problems. It is considerably more challenging than changing a fuse.

Our Convergence Gallery shows a variety of Convergence Faults. If you live in Toronto, ON., Calgary, AB., or Vancouver BC. it costs $257 for Hitachi in home convergence repair.

Good luck.

Red & green shadowing on the right side of picture


First thing to try is a convergence but with the red shadowing seems to me that you may have your color gun going. Convergence can be found in your video menu on your setup screen. Once in the menu you can adjust the colors to line up. This usually has to be done on a tv that has been moved.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the 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 wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms
  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

Color shadowing on white lettering


This is called convergence.
If the TV has auto convergence or 'Flash Focus', run it. All projection TVs have customer controls for minor adjustment. Give it a go with the menu or the remote convergence controls.
If not, this is a common adjustment made by a technician on a house call.
If the error is really big, say the colours are curved or you can see clear separate letters and things, you will need the convergence repaired. Get a quote - Usually about $300- $600 in home service.

This is what known as a convergence problem. First question is in your setup menu do you have a convergence option.. if you do then do you have any control in that mode does the crosshars move up and down and side to side... if you dont then you have a convergence power supply issue.. if you do it could be a setup issue. IF you do not have convergence in your setup menu then it possiblely be a special fuse.. and bad electrical connections. so let me know and ill see if we can narrow it down further

Hi did you check resistor protectors they are green pico fuses.

check your connections make sure all the wires are lined up with correct ones. I have done that lots of times.

In the menu you have to go to convergence and readjust the cross hatch each tv is a little differant to get to service menu you for adjustment..

keep me posted get me model number and i will get convergence code or the way to get into it for you .dont give up you will get it sometimes i go back to peoples houses a few times.
thanks doctor video.

If you have a problem with the convergence, believe me, going into the service menu and trying to correct it will only give you large headaches, DO NOT USE THR SERVICE MENU UNLESS YOU ARE A TRAINED TECH!!!! Doing so can result in a complete and total failure of this TV set. I service menu is not for any major changes in any adjustment. It is not the cure all. If your convergence all of a suddenly shifted, it is not a service menu issue. Your problem is the convergence amp IC's. Good Luck
