Your symptom sounds like at least one damaged convergence IC.

If you have a good low wattage soldering iron ~ 45W (available at radio shack) you can perform the repair yourself, and this will most likely take care of the entire issue.


I like to remove the board that the IC’s are on so that I can unsolder the connections and clean then up using solder wick (this is also available from radio shack). Removing the board is not a real issue as the connectors are all labeled with an alpha number, so that you can connect them back real easy. There are three in the middle towards the front that I like to mark with a sharpie as they are the red green and blue convergence coil connections (they are all the same size in a row). Just mark them with slashes, like I, II, III, or something like that. If you mix them up it is not a big issue, you can test swapping them around until the picture lines up.

Please be sure to remove the entire white heat sink compound on the heat sink and apply an even coating over the back of the new IC’s. You should also bolt them down before you solder them in so that you have them at the correct height.

There are two very large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink.

The IC’s are large and black, you cannot miss them. They will usually have an STKXXX-XXX number on them.

This repair from a good technician will normally run from $250.00 - $300.00, and sometimes more depending on your area.

There are several schools of thought on the replacement of parts and I firmly believe that you get what you pay for, so don’t buy the cheapest IC’s that you can find. One company I worked for tried this and it only caused more work for the technicians, as we had to replace them with the more expensive ones in the end. I would think that you should be able to find these for around $60.00 each. If you can find the exact
Hitachi part, or Sanyo, even though the numbers on the front are the same, and they look exactly like the $10.00 ones, they are better and more reliable.

I usually order my parts from Andrews Electronics in
California, they will have the OEM components that you will need.
Their site is http://www.andrewselectronics.com/welcome.aspx
And their phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the phone order so you can talk to the person about the different types of IC’s that are available.

You can also try http://www.tvrepairkits.com/ , I have not tried them yet, but they do carry OEM or better parts.

I hope this information allows you to resolve this issue.

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.

Tip

Hitiachi Convergence Circuit Resistor Values


This site has been very helpful in diagnosing and repairing my Hitachi 57XWX20B. I recently changed the IC's and a resistor to fixe a convergence problem and had to use the small button on the convergence circuit to get set to return from static mode and enter dynamic mode. I searched everywhere trying to locate the correct resistor values and noticed many other's needing the same information. Here are the results of my research. I obtained some from manuals and others from comparison of the different models. My main focus was finding the values for the 57XWX20B. The resistor values are given in ohms at 1 watt. This means RK42 is a 3.3 OHM 1 watt resistor. RK58 was the problem in my set. It was giving a value of 2.3 and needed to be 4.7. I first replaced the IC's and thought the resistors were all good, but I later noticed my convergence was off. I could manually align it but the magic focus initiation would not save. It gave an overflow error. I bought the sanyo brand of IC's, not the cheap inports and found that if you use a desoldering wick then the repair is easy. The new IC's restored the beautiful color the set had when new. Now it is brilliant as well as converged. My repair cost was:
STK-110 13.00 Bought from local electronic supplier
STK-150 15.00
RK58 3.00 Bought from a local TV repair shop

The elecronic supply store gave me 6 inches of desouldering wick
Total cost: 31.00 Dollars

How do you line up bulbs with remote


This set with front grill removed has a tiny blue button on front edge of chassis on left side that will manually take set to convergence mode but you must have the Hitachi working remote to do adjustments---different buttons on the remote adjust and save the adjustments, I have the Hitachi book that shows all remotes they use and which buttons do what---if convergence is real bad most likely the two chips for convergence need to be replaced if Magic focus will not help.

one of two things on this model==clean the lens on top of the chassis--the round large black ones.

Second: there is a resistor in the power supply that changes value and will cause this----also with set unplugged and back off since set was moved carefully look for any plugs not fully seated etc.

It sounds like a convergence failure. Often replacing the two Convergence ICs and the 6 associated resistors will repair that issue. You can get the convergence repair kits which contain the parts and the CD with instructions from www.tvrepairworld.com

Magic focus does not work. RGB projections do not line up.


That symptom is usually caused when the convergence ICs and associated resistors fail. You can get convergence repair kits for the various Hitachi models from www.tvrepairworld.com the kids contains both ICs and the associated resistors plus the CD with repair instructions.

The power source detects an overload on one of its exits and shuts down to protect itself. The tv must be opened and tested by a knowledgeable person who can identify and replace the failed part.

The Convergence IC's need to be replaced. They are located on the Board to the right, mounted on a large heat sink. They should be replaced with STK392-150's. The original IC's are probably STK392-110's.
The Stk392-150 is a updated replacement. Be sure to use Heat Sink Compound between the IC's and heatsink because these IC's do draw alot of current and heat up alot. Also look for any heat stressed Resisters.
I hope this helps,

Manual Convergence adjustment on Hitachi 43UWX10B


I would guess you missed a open resistor--there are only about 12 of them--how did you check them?

This set (43uwx10b) has a tiny blue micro switch on the front of the chassis---if you engage it from the front the set will go into the DECAM or convergence mode--let me know the CLU number on your original remote and I will scan and paste instructions---98% of the time if the set is wacked out and will not adjust one of the resistors is gone---ONE OF THE CHIPS GETS THEM.
