Question about Hitachi 50UX57B 50" Rear Projection Television

3 Answers

Hitachi 60" rear projection, convergence

While watching our 11-year old TV, the convergence jumped out of setting. The red goes off-center and cannot be reset. Sometimes it works OK, but more not. I noticed that if you bump the cabinet, the picture jumps too, didn't before. Cold solder joint, or other?

    Yes I had the exact same problem. But also I have an inverted bowing the horizontal edges. I checked the board while it's on and found all of the green lights are on exempt for the one closet to the main power supply.

    For your convergence problem I've found that if your press the service mode button on the front of board and use the number buttons on the remote, you can adjust the position of the red and blue (green is stationary). I hope this helps you. Can someone help me with the bowing effect?

I have the 70" model. The convergence chips are failing. They aren't hard to replace if you have some soldering experience. Once you replace the chips, it's always good to follow the the "Service Mode" Convergence allignment and save.

Check your owner's manual and see if there are instructions for setting the convergence. This lines up the different color guns so that you don't need your 3D glasses. If setting the convergence doesn't work, you may need new IC chips. Good luck!

If the picture was good prior to the 3D images, I would fix it. The convergence ICs either have poor connections or are defective. The IC is an STK392-110. There may be 2 inside the set. If you have this repaired, expect a labor cost in the $200 range. Request that the ICs be replaced rather than the board changed. This will maintain all of the internal settings and require only part replacement not a complete re-convergence adjustment.

Keep us posted.

Convergence


You need to most likely replace the convergence output IC's probably STK392-110's and check associated resistors around it. HD is not mandated for 2009, only digital braodcast it is at that point all analog television broadcast must stop.
