53 FDX 20B Red Alignment

My red alignment is out and I was wondering if there was an adjustment for this. I have used the "Magic Focus" button, which did absolutly nothing for the picture. Any suggestions would be greatly appreciated.

I have a 53 inch hitachi ultravision #53UDX10B Its out of focus and when you press the magic focus button it trys then pops up with the # 4 in the corner is this a convergence problem or what ?

Yes, you have a convergence failure. Usually requires replacement of 2 X STK ICs and any burnt resistors associated with the function that is faulty.

Look at the user menu and compare with images on our Convergence Gallery. Try to adjust in the convergence adjust menu. Identify the functions that do not work and make note. When you replace the ICs, pay special attention to the low ohm resistors for the non-working function. They will be located near the colored plug associated with the non-working function. If red vertical will not adjust, check resistors near the red plug.

There are many posts and websites that offer "new and improved Convergence IC substitutes. My advice is to use the original part numbers and replace any burnt resistors with original values. Many ICs purchased on the Internet are very poor quality and do not work. Many users get substitute replacement ICs and never get their TVs working again.

If you have other electronics repair experience, this job may be done with some chance of success. If you have no experience, there are many secondary problems that can and usually do appear. Determining how to fix the secondary faults and how to correctly align the TV is difficult without prior convergence repair experience.

Some of the common problems encountered are:
1. Poor solder techniques, resulting in damaged PC boards or poor solder connections.
2. Poor quality or wrong parts installed and recognizing this problem.
3. Resistors open or burnt. Some resistors are weakened by the initial faulty IC. Replacing with a "good" IC and starting the TV causes the weakened resistors to burn up. IC may be ok but there are one or more open resistors that measured ok when ICs were being replaced.
4. Wrong ICs used, causing resistors to burn up.
5. Resistors that measure normal and become faulty when heated by current flow.
6. Recognizing that convergence circuit is repaired correctly and alignment is needed.
7. Major alignment in service menu required because data is corrupted by multiple tries of magic focus or manual adjustment while faulty circuit conditions exist.
8. Major alignment required because user adjusted centering rings or physically changed mechanical focus adjustment, then mis-adjusted convergence settings trying to correct mechanical alignment faults.
9. User has not connected plugs and connectors correctly and caused secondary damage or mis-alignment trying to correct secondary issue.

Physically replacing the ICs may appear simple but recognizing if a fault still exists or if correct repair is required causes many attempts at repair to fail. Keep it simple. Replace with good quality original part numbers, measure suspect resistors and adjust only what is necessary.

There are only 3 things to fix, IC failure, resistor failure and user induced secondary faults. Data processor and memory is bulletproof.

Hitachi 53FDX 20B: Convergence Sanyo IC's installed

You need to fix the convergence chips 1st.

This is a common problem. Its called a convergence failure.

Problem #1) Convergence


  • Screen Looks 3D
  • Colors wont align
  • Video may look distorted
Problem #2 CRT Fluid has clouded over. Symtoms

  • Dull looking video
  • White looking video
  • Halos around objects
  • Red/Orange looking video

You can see some examples and find a fix here...

Alignment Issue with model 53SDXBA Magic Focus doesn't correct.

A little hard to explain:there is a small micro switch on the front of the main circuit board(very small and usually button on it is blue) this will take the set into the CONVERGENCE MODE---DEPENDING on the number on the remote(CLU5722tsi etc) different buttons on the remote are then used to navigate and to adjust convergence; some buttons will allow you to change from red to blue; others will change the grid that will appear when you engage the micro-switch from fine to coarse---this set should have a remote with clu-615mp marked on the outside of it. If you need full information I can provide a detailed copy of instructions via email for this set and this remote-----after all convergence is aligned you have to use the remote to SAVE the adjustments---if you think this is beyond you---get a tech to do it---these sets are easy to align for convergence(presume you do not have a convergence problem) and it is easy to do after you know how.

Have a 53" Hitachi HDTV that bows at the top and the bottom. I was told one of the transitors or transformes blew. I also do not have the regular magic focus just the static focus now. I tried to alli

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.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

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. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems.



Here is a quick test....

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. And you should be able to get the grid straight.

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 fix


You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

Magic focus works briefly, then the tv is out of alignment

You need to replace the convergence chips and possibly some of the convergence resistors. You can buy the parts online from various sources or you can get a complete kit with instructions from

I have the exact same just explained it a hell of a lot better than me. In the magic focus was red broken up, blurred and flashing as well as only 3 bars???
If you solved your problem could you please get back to me.
Thank you

the convergence IC`s and associated resistors have to be replaced, do not repeatedly push magic focus or the alignment after the parts change out will take longer which of course means higher repair bill, good luck
