I have a yellow swoosh (shape of the nike swoosh) on the top of my screen with a blue 2" inch line under it. I also have a blue spot on the bottom left of my screen. I hit the Magic Focus to see if that would help and it did nothing. Help!

Yes - You will need to either remove the circuit board or lift up the tray. If you are not sure how to do it yourself read the link below.

  • This is a very common failure on Projection TV sets.
  • 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.

Color sepatation

thats the convergence ICs and associated resistors your model is the DP14G chassis and the Hitachi DP14G convergence kit is available from and includes the two ICs associated resistors and the cd with repair instructions.

My tv has a bow in it every time a banner comes across

It is not unusual in these sets for things not to be perfectly straight---if the set has recently been repaired for a Convergence problem--someone may not have adjusted it correctly.

Understand: if it is a 43uwx10b Hitachi:

The green convergence is adjusted first for a grid of straight lines up and down and left/right---if the green grid is not straight you are going to see a bow when things scroll across the screen.

The other possible problem you may have is a convergence problem--if you go into the customer menu and try to adjust convergence--not the magic focus-- are the blue and red adjusting or not?

I know the HItachi sets very well--I own two of them and have repaired hundreds of them.

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.


As stated in your response to another person (Hitachi 43UWX10B)

Your post didn't get attached to the message in which you read the 'fix' for your set so the person who helped, will likely never see it.
You might try re-entering your brand/model info and sort through the results to find the original message.

The magic focus will stop if there is a bad sensor and or a problem in the convergence circuit.

This set uses two STK-392-110 convergence chips--both along with any of the resistors that protect them need to be replaced and the set adjusted--I have repaired hundreds of these sets----

Confirm model number----and if you go into the customer menu and either red or blue will not move in any or some direction--the chips have to be replaced---LET ME KNOW WHAT YOU FIND AND I CAN GIVE YOU FAIRLY DETAILED INSTRUCTIONS ON WHERE TO GET THE PARTS AND WHAT IS INVOLVED IN THIS REPAIR.

They are Big Black ICs will have STK on them they are startup and convergence ICs They control set to turn on and off and convergence. Look for board that has them on it.2 of them together. If they are 110s use 180s ,Let me know what # on STKs you have.

Color convergence

If your model is 43UWX10B you need two STK392-110 Convergence ICs. and one each of the following 1watt reseistors. 3.3 ohm, 1.8 ohm, 2.7 ohm, 1.5 ohm, 3.9 ohm, and 2.2 ohm they are in order RK42, 46, 50, 54, 58 and RK60.
