You need to replace both STK392-110 Ics and then you need two 2.2 ohm 1 watt resistors, two 1.5 ohm 1watt resistors and one 3.3 ohm 1watt, and one 1.8 ohm 1watt resistors. You can get replacement ICs and resistors at the following link with free instalation instructions with pictures. Heres the link.

    Those are the right ICs and resistors if your model is the 43FDX01B they dont have the kit for that paticular model. They are very easy if you get the desoldering iron that there instructions specify its 14.00 at radio shack and it makes doing the repair a snap. Plus they hook you up with free online instant messageing when you do the repair in case you have any questions.

Red and blue convergence wont line up. What should i do.


convergance can be tricky and you should follow a manufacturers proceedure from a manual.

most specificaly start with the green H and V Linearity and center , then the Red and Blue

Projection TV's and Component Video RGB have their Horizontal and Vertical Sync signals on the Green Component..

There may be other reasons for their specific order of operations within a calabration proceedure such as your 'RGB convergance alignment'

Hitachi 43FDX01B green is out of whack


The green is not adjustable in the customer menu because it is considered the 'master' color. It is adjustable in the technician mode however but if it is curved it won't even adjust properly that way either. The problem is the convergence ampifier responsible for green convergence has failed. The convergence output IC's need to be replaced.

Convergence lines are SLANTED. Red line is above


Your TV most likely a convergence failure. ( 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.
Here are some photos of convergence problems.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

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

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.

Re: 43FDX01B blue convergence issues


Ditto CTF1800's comment....Check RP-41 1.5 ohm 2 watt and
other low value resistors near IC's mounted on large heatsinks.

STK392-110 original convergence IC's can be upgraded to
Hitachi # CZ 01341 new number STK394-160E for greater reliability.......Hitachi also has an IC / resistor kit # X480295,
but I don't change good resistors, only the bad one(s).

Practice good visual acuity technique and ask questions!.....T.

Hitachi 43FDX01B rear projection TV


It is adjustable only in the technician menu. You will most likely need to replace the convergence IC's in the TV. This is a very common issue. The locations are IK04 & IK05 and are generic part numbers STK392-110's.
