Blue convergance on Hitachi 43FDX10B

Hello Techman,
This is a 2nd go round with this problem for me. Last time it was under Svc Agreement and covered. The tech explained it as a common problem. I'm rather experienced in electronics repair (25 yrs. avionics, CAT scanners & MRI's). I just need to know what parts to replace and what sort of calibration may be necessary. Would it be easier and better to replace the entire blue convergance PCB, or the discreet components. Please guide me with part numbers and where to access them.

Thanks,
Mike Vos

    I have blue shadows on screen. I have never repaired a T.V. Is this a simple fix? How much would this cost me?

Screen is bliry and has a few blue lines kind of like a outline


This is a common problem called convergence, I will attach a few photos of typical convergence problems.

In your set it is a fairly easy repair but does require being able to get at the two convergence chips.

Parts cost will be under twenty dollars (I can tell you best place to find them)

If you are able to solder let me know and I will assist you.

Hitachi Projection TV will not turn on just blinking power light


There is a board on the right side of the tv called the convergence bd

There are little connectors that are on the left of the board
the last one is the power to the convergence Ic's

That is the one that is closest to you. they are little black conectors with wires in them


Carefully lift it up

Then plug the tv back in and see if it fires up

If it does do not run it long

just enogh to see the tubes light
then shut if off

If it goes on

your convergence ic's are Shorted

They have a kit for this tv it is available through local parts distributors
If you can't find it locally just Google HITACHI CONVERGENCE KIT

If you are not good with de-soldering and soldering do not attempt this repair. Remember to replace all the resistors in the kit

If you are not sure about doing this repair you should have your local tv guy do it for you


If it does not go on then I would suspect the regulator in the power supply But
Most of the time it's the ics

Blue convergence


Thats the classisc sign that you need to replace both convergence ICs. You will need two Convergence ICs STK392-120 and then six resistors they are RK42 3.3 ohm 1watt, RK46 1.5 ohm 1watt, RK50 2.7 ohm 1watt, RK54 1.5 ohm 1watt, RK58 3.9 ohm 1watt, RK62 1.8 ohm 1watt. You can get replacement ICs and resistors at the following link and they provide free instalation instructions with pictures so you can repair the set yourself. Heres the link.

Chirping noise and flashing front power light.


Theres a short somewhere in the set. Most likly the HOT is shorted or the vertical IC has caused this in the past. In one case I had shorted convergence IC cause this symptom.. This set is solid state and there are no user serviceable parts inside so please call a trained tech to assist you with this problem Good Luck
