Not that bad to remove

As long as it is unpluged you won't get shocked

Look to the right of the boards Remove all the little screws from the convergence board
Make sure you mark or notate where the correctors go

Flip up the little connectors to the left of the board
Do not force the board up if you have to force it you missed a screw

use solder wick and remove the parts

make sure there are no shorts and you replace all the resistors in the kit

Good luck

Solution:
Your TV has a convergence problem. Here are some of the most common symptoms.

Screen looks 3D
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed in but stationary.
Here is a quick test....
Using your original remote go-to the tv settings then goto the convergence or magic focus 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 can get a repair kit that includes all the parts from www.TvRepairKits.com.
They have put together a kit for the Hitachi TV sets.
The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself. Its a fairly easy fix on the Hitachi sets.

Hitachi 43fdx20b Need capacitor but i dont know which to buy!!


Hello Soleftright,

I have CK24 as a 1000pf 50v cap. Look at CK25 it is the same value as CK20 - CK24. Were your convergence ICs STK392-110s? One side of the cap goes to pin 14 of the (IK-04) IC and the other to ground.

I hope this helps
Thank you,

Hitachi 61swx10B digital rear project


Yes it certainly sounds like you have the old convergence outpuyt IC's that have gone bad in this TV set. If you have the soldering skills, and know how to work on printed circuit boards, you can repolace both of the STK convergence IC's. If you do not, you can get the complete convergence board at http://www.ptscorp.com, and the Hitachi board number is JT22056. Good Luck
