    Thanks, I was looking at the parts area, is there a repair kit or do the parts ned to be ordered individually... I noticed a few kits out there... Are the SDK's easy to see and should I chck the part number on them before ordering?



    Again, thanks for the help....

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.

Your Convergence ICs are likely failing. It is very common on rear projections. The solution is to replace the STK chips, check fuses and the resistors next to the STK chips. Replace as necessary and re-align via the service menu. It is about a $300 repair at a tv service center. You will need the service manual if you decide to do this yourself.

Try This:
When you notice the symptons Use this simple test to verify.
Go to the users menu on the tv.
Look for the converge option probably under setup or video setting. Converge is short for convergence to align the red and blue colors to the green color.

If you cannot move the red either horizontal or vertical, then the STK chip has failed for red section.
If you cannot move the blue either horizontal or vertical, then the STK chip has failed for the blue section.

If you can move both in each direction then the problem is something else.


Note if one STK chip fails, you replace both regardless. They will be right next to each other.

Red vert lines will not convergenge(sides) blue and green o.k.


your convergence output amps are done...
you have to do repair on the convergence output circuit, and inspect
the power supply for any damages.

Multi-point convergence -- Lower left quadrant of screen distorted. Red ok. Blue arched up and then done to normal in Lower right quadrant; left-right adj moves vertical gridline but is s-shaped. Blue...


Look in users manual or internet you should find how to access service mode, this is different from regular setup CONVERGENCE, this involves getting into changing parameters to tweek convergence, even after amps are changed. These projection tv's are known for loosing convergence if bumped, moved and amps go bad in time.

Hitachi convergence seems to be bad, but all resistors check in spec's can you check ic's the cross hach lines will move in all directions but some are bent


I know this set very well, have fixed hundreds of Hitachi sets with convergence problems--

first--did you just go into the customer menu?

There are two ways to get into the tech convergence mode on most of these sets---if the set has "MAGIC FOCUS" PRESS the button the front panel---while magic focus is running press magic focus again --if STOP is displayed on the screen press either RECALL OR STATUS BUTTON ON THE REMOTE--set will go to the tech convergence mode--take a good look there ---if red or blue is skewed most likely one or both of the 2 STK-392-110 CHIPS THIS SET USES IS BAD--NO WAY TO TEST THEM--IF RESISTORS ARE ALL GOOD--you have to replace BOTH chips to see if one is your problem.

You can also get into the tech convergence mode by removing the front speaker grill and inspection plate behind it----there is a tiny micro switch on the front of the board (little blue button) with something not metal--touch it with the set on and you will be in the convergence mode.


I presume you know how to navigate with the remote in this mode 2,4,6.8 to move--ant to select blue and 0 to select red---enter button will stop blinking cursor and you use the ARROW CURSORS to adjust---DO NOT TOUCH ANY OTHER BUTTONS---

What you are looking for is will the "bent" lines adjust.

If the answer is no--change the two chips and see what you have--The STK-392-110 chips can also be replaced with STK-392-150 chips---they are a longer life version of the original chip.

If you need help doing the repair ask me before you begin.

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.

Red Green Blue horizontal line at top of screen


Since both were replaced at one time, you now can't limit the problem properly. Should have been done one at a time.

Your vert height may be too short, causing you to be seeing things that should be off screen.

This can be remedied in the service mode.

Picture issues


It sounds like a convergence issue and possibly the amps themselves going out.. Cycling the unit off/on has me suspecting convergence amps first and possibly poor solder connections in the vert or convergence circuit. However, it could be one other thing, Vertical misadjusted. There is a methid for checking that in the service menu and I'll get to that in a second. The symptoms correcting themselves when you cycle on/off is very significant. I would first check for poor solder connections on the vert IC, and conv. amps. Then test the convergence amps themselves. If all else fails check the vertical adjustment. To adjust vertical enter service alignment mode by using 06-25-96 status, after entering service alignment mode it will be necessary to use the A/V button to get back to A/V4. When in the service alignment mode cursor down to GDE SAM. Cursor right and then cursor down to Geometry. Cursor right and then cursor down to VER. AMPL. then while watching the DVD in A/V4 cursor right or left to adjust the vertical amplitude until the white lines just disappear. Turn the set off to save the change. NOTE: Convergence may need to be touched up slightly after this adjustment has been made. Footnote: mnyce, this is one repair that I would not attempt unless you are fairly skilled at trace testing and knowing what to look for in a given circuit. As always, there are voltages in these areas that could harm you or further damage the unit. I would suggest contacting an honest qualified repair facility and explain your problem to them. Most will have no problem telling you exactly what I have here.. Goodluck. Bill

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.
